It may be able to share some partitions with other Unix systems, but that's not covered here. At the very least you will need a dedicated partition for the Ubuntu root filesystem. Apple’s Mac computers have their own operating system, OS X. Most of the programs that are available for PCs are also available for Macs running under OS X, but these two types of computers cannot use the exact same programs: for example, you cannot install the Mac version of the Microsoft Office suite on a Windows computer.

This article is primarily for network administrators and other people who manage their own network. If you're trying to join a Wi-Fi network, one of these articles should help:

• Mac: Connect to Wi-Fi and resolve Wi-Fi issues.
• iPhone, iPad or iPod touch: Connect to Wi-Fi and resolve Wi-Fi issues.

About privacy and security warnings
If your Apple device displays a privacy warning or warning about the weak security of a Wi-Fi network, that network could expose information about your device. Apple recommends connecting to Wi-Fi networks that meet or exceed the security standards outlined in this article.

Before changing the settings on your router

1. Back up your router's settings, in case you need to restore them.
2. Update the software on your devices. This is critical for ensuring your devices have the latest security updates and work the best they can with each other.
   • First, install the latest firmware updates for your router.
   • Then, update the software on your other devices, such as on your Mac and on your iPhone or iPad.
3. On each device that had previously joined the network, you may need to forget the network to ensure the device uses the router's new settings when rejoining the network.

Router settings

To ensure that your devices can connect securely and reliably to your network, apply these settings consistently to each Wi-Fi router and access point, and to each band of a dual-band, tri-band or other multi-band router.

Security

Set to WPA3 Personal for better security
Set to WPA2/WPA3 Transitional for compatibility with older devices

The security setting defines the type of authentication and encryption used by your router, and the level of privacy protection for data transmitted over its network. Whichever setting you choose, always set a strong password for joining the network.

• WPA3 Personal is the newest, most secure protocol currently available for Wi-Fi devices. It works with all devices that support Wi-Fi 6 (802.11ax), and some older devices too.
• WPA2/WPA3 Transitional is a mixed mode that uses WPA3 Personal with devices that support that protocol, while allowing older devices to use WPA2 Personal (AES) instead.
• WPA2 Personal (AES) is appropriate when you can't use one of the more secure modes. In that case, also choose AES as the encryption or cipher type, if available.

Weak security settings to avoid on your router

Don't create or join networks that use older, deprecated security protocols. These are no longer secure, they reduce network reliability and performance, and they will cause your device to display a security warning:

• WPA/WPA2 mixed modes
• WPA Personal
• WEP, including WEP Open, WEP Shared, WEP Transitional Security Network or Dynamic WEP (WEP with 802.1X)
• TKIP, including any security setting with TKIP in the name

Settings that turn off security, such as None, Open or Unsecured, are also strongly discouraged. Turning off security disables authentication and encryption and allows anyone to join your network, access its shared resources (including printers, computers and smart devices), use your Internet connection, and monitor the websites you visit and other data that's transmitted over your network or Internet connection. This is a risk even if security has been turned off temporarily or for a guest network.

Network name (SSID)

Set to a single, unique name (case sensitive)

The Wi-Fi network name, or service set identifier (SSID), is the name your network uses to advertise its presence to other devices. It's also the name that nearby users will see on their device's list of available networks.

Use a name that's unique to your network, and make sure all routers on your network use the same name for every band they support. For example, don't use common names or default names, such as linksys, netgear, dlink, wireless or 2wire, and don't give your 2.4 GHz and 5 GHz bands different names.

If you don't follow this guidance, your devices may not connect reliably to your network, to all of the routers on your network or to all of the available bands of your routers. And devices that join your network are more likely to encounter other networks that have the same name, and then automatically try to connect to them.

Hidden network

Set to Disabled

A router can be configured to hide its network name, or SSID. Your router may incorrectly use 'closed' to mean hidden, and 'broadcast' to mean not hidden.

Hiding the network name doesn't conceal the network from being detected or secure it against unauthorised access. And because of the way devices search for and connect to Wi-Fi networks, using a hidden network may expose information that can be used to identify you and the hidden networks you use, such as your home network. When connected to a hidden network, your device may display a privacy warning due to this privacy risk.

To secure access to your network, use the appropriate security setting instead.

MAC address filtering, authentication and access control

Set to Disabled

When this feature is enabled, your router can be set up to only allow devices that have specified media access control (MAC) addresses to join the network. Reasons why you shouldn't rely on this feature to prevent unauthorised access to your network:

• It doesn't prevent network observers from monitoring or intercepting traffic on the network.
• MAC addresses can easily be copied, spoofed (impersonated) or changed.
• To help protect user privacy, some Apple devices use a different MAC address for each Wi-Fi network.

To secure access to your network, use the appropriate security setting instead.

Automatic firmware updates

Set to Enabled

If possible, set your router to install software and firmware updates automatically as they become available. Firmware updates can affect the security settings available to you, and they deliver other important improvements to the stability, performance and security of your router.

Radio mode

Set to All (preferred),or Wi-Fi 2 to Wi-Fi 6 (802.11a/g/n/ac/ax)

These settings, available separately for the 2.4 GHz and 5 GHz bands, control which versions of the Wi-Fi standard the router uses for wireless communication. Newer versions offer better performance and can support more devices concurrently.

It's usually best to enable every mode that's offered by your router, rather than a subset of these modes. All devices, including older devices, can then connect using the fastest radio mode they support. This also helps reduce interference from nearby legacy networks and devices.

Bands

Enable all bands that are supported by your router

A Wi-Fi band is like a road that data can flow down. More bands provide more data capacity and performance for your network.

Channel

Set to Auto

Each band of your router is divided into multiple, independent communication channels, like different lanes on a road. When channel selection is set to automatic, your router will select the best Wi-Fi channel for you.

If your router doesn't support automatic channel selection, choose whichever channel performs best in your network environment. That varies depending on the Wi-Fi interference in your network environment, which can include interference from any other routers and devices that are using the same channel. If you have multiple routers, configure each one to use a different channel, especially if they are close to each other.

Channel width

Set to 20 MHz for the 2.4 GHz band
Set to Auto orall widths (20 MHz, 40 MHz, 80 MHz) for the 5 GHz band

Channel width specifies the size of 'pipe' available to transfer data. Wider channels are faster but more susceptible to interference, and also more likely to interfere with other devices.

• 20 MHz for the 2.4 GHz band helps to avoid performance and reliability issues, especially near other Wi-Fi networks and 2.4 GHz devices, including Bluetooth devices.
• Auto or all channel widths for the 5 GHz band ensures the best performance and compatibility with all devices. Wireless interference is less of a concern in the 5 GHz band.

DHCP

Set to Enabled, if your router is the only DHCP server on the network

Dynamic host configuration protocol (DHCP) assigns IP addresses to devices on your network. Each IP address identifies a device on the network and enables it to communicate with other devices on the network and Internet. A network device needs an IP address, much like a phone needs a phone number.

Your network should only have one DHCP server. If DHCP is enabled on more than one device, such as on both your cable modem and router, address conflicts may prevent some devices from connecting to the Internet or using network resources.

DHCP lease time

Set to 8 hours for home or office networks; 1 hour for hotspots or guest networks

DHCP lease time is the length of time that an IP address assigned to a device is reserved for that device.

Wi-Fi routers usually have a limited number of IP addresses they can assign to devices on the network. If that number is depleted, the router can't assign IP addresses to new devices, and these devices can't communicate with other devices on the network and Internet. Reducing DHCP lease time allows the router to reclaim and reassign old IP addresses that are no longer being used faster.

NAT

Set to Enabled, if your router is the only device providing NAT on the network

Network address translation (NAT) translates between addresses on the Internet and addresses on your network. NAT can be understood by imagining a company's post room, where deliveries to employees at the company's address are directed to employee offices within the building.

You should generally only enable NAT on your router. If NAT is enabled on more than one device, such as on both your cable modem and router, the resulting ”double NAT” may cause devices to lose access to certain resources on the network or Internet.

WMM

Set to Enabled

WMM (Wi-Fi multimedia) prioritises network traffic to improve the performance of a variety of network applications, such as video and voice. All routers that support Wi-Fi 4 (802.11n) or later should have WMM enabled by default. Disabling WMM can affect the performance and reliability of devices on the network.

Device features that can affect Wi-Fi connections

These features may affect how you set up your router or the devices that connect to it.

Private Wi-Fi Address

If you're connecting to a Wi-Fi network from an iPhone, iPad, iPod touch or Apple Watch, find out more about using private Wi-Fi addresses in iOS 14, iPadOS 14 and watchOS 7.

Location Services

Make sure your device has Location Services turned on for Wi-Fi networking, because regulations in each country or region define the Wi-Fi channels and wireless signal strength allowed there. Location Services helps to ensure your device can reliably see and connect to nearby devices, and that it performs well when using Wi-Fi or features that rely on Wi-Fi, such as AirPlay or AirDrop.

On your Mac:

1. Choose Apple menu  > System Preferences, then click Security & Privacy.
2. Click the lock in the corner of the window, then enter your administrator password.
3. In the Privacy tab, select Location Services, then select Enable Location Services.
4. Scroll to the bottom of the list of apps and services, then click the Details button next to System Services.
5. Select Wi-Fi Networking, then click Done.

On your iPhone, iPad or iPod touch:

1. Go to Settings > Privacy > Location Services.
2. Turn on Location Services.
3. Scroll to the bottom of the list, then tap System Services.
4. Turn on Networking & Wireless (or Wi-Fi Networking).
   

Auto-Join when used with wireless network provider Wi-Fi networks

Wireless network provider Wi-Fi networks are public networks set up by your wireless network provider and their partners. Your iPhone or other Apple mobile device treats them as known networks and connects to them automatically.

If you see a ”Privacy Warning” under the name of your network provider's network in Wi-Fi settings, your mobile identity could be exposed if your device were to join a malicious hotspot impersonating your network provider's Wi-Fi network. To avoid this possibility, you can prevent your iPhone or iPad from automatically rejoining your network provider's Wi-Fi network:

1. Go to Settings > Wi-Fi.
2. Tap next to the wireless network provider's network.
3. Turn off Auto-Join.

In recent years, I’ve had the opportunity to experience the Apple Mac OS X platform on a 13″ Macbook Pro Retina as my “daily driver.” I’ve been using the Macbook Pro, instead of my Dell Latitude E6430, on a daily basis, and wanted to share my findings with the world. To offer you some background, I’ve been working in the IT field since 2004. I work heavily with technologies such as Windows Server, Linux, Python, PowerShell, Amazon Web Services (AWS), Microsoft Azure, and System Center.

Under this section, we’ll talk about some of the essential software packages that you should have for your Mac. You might find that some of these tools are useful for you, while other tools may not be applicable to you. Since I work heavily with enterprise cloud and automation, some of these software packages will be specific to software developers.

TeamSQL

If you’re working with relational databases, such as MySQL, Postgres, or Microsoft SQL Server, there’s a free, cross-platform GUI tool called TeamSQL. The app has a nicely polished user interface, and is pleasant to use.

Authy

If you need a two-factor application that is synchronized across desktop and mobile devices, check out Authy. You can use Authy for two-factor authentication (2FA / MFA) for services like Coinbase, Amazon Web Services (AWS), and others. There’s a Mac, Windows, Android, and iOS version of the application.

DB Browser for SQLite

If you need a program to manipulate SQLite databases, you can download the free, open source package called SQLite Browser (DB4S).

dbKoda

If you’re a software developer, working with MongoDB, you might want to check out this free, open source tool to help manage MongoDB databases. It’s a tool called dbKoda, that runs on Mac OS, that’s developed by an Australian software company called Southbank Software.

Disk Inventory X

Is your disk getting full on your Mac? Check out the Disk Inventory X utility, similar to the WinDirStat application for Windows. This utility will help you identify applications and files that are using up a large portion of your disk space, so that you can delete them and free up some storage space for new files. Boxes, shaded with different colors, represent individual files on the filesystem, and will draw your visual attention to them. Larger boxes indicate larger files, while small boxes indicates smaller file sizes.

Hyper

A company called Zeit has create an alternate terminal interface for Mac OS X named Hyper. Hyper is based on GitHub’s Electron user interface API and is built on web standards. The source code for the Hyper project is available on GitHub.

Royal TSX

If you’re working with the Microsoft Windows platform, you’ll frequently need to use Remote Desktop Protocol (RDP) to connect to remote systems. The same thing applies if you are managing Linux systems remotely, where you’ll typically use SSH to connect to them. The software package called Royal TSX provides a plugin-based architecture, whereby you can perform many different types of remote management tasks from a centralized interface.

iTerm2

If you’re a heavy command line user, iTerm2 is an essential package. While Mac OS X has a built-in terminal application, it leaves a lot to be desired.

Tmux

If you’re looking for an alternative to the screen command, which allows you to open multiple terminals in a single window, check out tmux instead.

Atom Editor

The Atom Editor is a great, graphical text editor that’s useful for programming tasks, anywhere from Bash, to Python, Ruby, JavaScript, CSS and HTML. What’s really neat about Atom is that it’s being developed by the team at GitHub. Similar to the well-known, but infrequently released, Sublime Text tool, Atom offers a framework for extensibility, and a package repository containing many useful add-ons.

Another great feature of the Atom Editor, if nothing else, is that it has built-in Markdown rendering. If you’re looking for a simple, free tool to view and edit your Markdown, Atom might be just the tool you need!

Microsoft Remote Desktop Client

The Microsoft Remote Desktop Client for Mac enables you to access your Windows systems remotely. For those who are unfamiliar with RDP (Remote Desktop Protocol), it essentially allows you to remotely connect to your Windows computer and treat it as if it were running locally. If you’re using a Mac, and need access to a Windows-specific application, such as PowerShell, this quickly becomes extremely useful.

You can connect to Windows virtual machines that are running in the Microsoft Azure public cloud, which allows you to rapidly spin up, or spin down, Windows-based virtual machines on-demand. You only pay for what you use, and as long as you shutdown (deallocate) your VMs when you’re not using them, you’ll keep your monthly bill pretty small!

Microsoft Office

Although Apple includes their own document editor, spreadsheet program, and presentation software, if you’re already familiar with Microsoft Office, then you’ll probably want to keep using it. The Mac version of Microsoft Office has some shortcomings, that the Windows version doesn’t have, but for the most part, it is going to get done about 90% of what you’re looking for.

As a heavy user of Microsoft PowerPoint, one of the things that I noticed was missing out of the Mac version is the Selection Pane. On a Windows system, with Microsoft Office, the PowerPoint Selection Pane allowed you to quickly rename objects on your slides, and toggle their visibility. For me, this was a great workflow enhancement, but I’ve been able to get by without it. I’m hopeful that Microsoft will add this back in a future version.

Google Chrome

There isn’t a lot to say here, for users who are already familiar with Google Chrome. However, if you haven’t heard about Google Chrome yet, it is pretty much the best web browser in existence. Tight integration with your Google accounts, high performance, and. This browser is well-known for using a lot of memory, but that’s actually a good thing. Barring any major software bugs / memory leaks, the more memory a program uses is a reasonably good indication that it will be able to more quickly respond to user input.

VirtualBox

On Mac OS X, there are a variety of virtualization solutions that can help you run Linux or Windows on a localized Virtual Machine. Although you can easily deploy virtual machines in cloud platforms, such as Microsoft Azure or Amazon Web Services (AWS), in situations where you aren’t connected to the Internet, you might need to run a Virtual Machine locally on your Mac. That’s where Oracle’s VirtualBox solution comes into play. VirtualBox is a free and open source (FOSS) software package that enables you to create virtual machines in a matter of seconds.

I was able to successfully use VirtualBox to install a Windows 10 Enterprise Build 1152 using the ISO file from MSDN. I plan on using this VM for software testing, particularly with PowerShell.

Visual Studio Code

Although I’ve mentioned the Atom Editor, another project you’ll want to keep an eye on is Visual Studio Code. Although Microsoft’s premier software development tool, the full version of Visual Studio, only runs on the Windows platform, Microsoft is making a huge investment into cross-platform software. The Visual Studio Code editor provides revision control integration with Git, syntax highlighting, and it even supports debugging through a debug adapter.

Projects in VS Code can be simply opened as folders on the filesystem, so there’s no need to go through the process of creating a project in the same way you’re used to in the full version of Visual Studio.

Sonos

For those of you who are new to Sonos, you have to buy Sonos proprietary hardware. Essentially, they’re an intelligent, wireless (proprietary, not WiFi) speaker system that enables you to play audio from nearly any source, including Pandora and online radio stations. I’ve owned two of the Sonos Play:5 speakers, and a Sonos Bridge since about 2012, and absolutely love the audio quality, and flexibility that this system offers. One of the things I really love about the Sonos audio system is that it provides perfectly synchronized audio within a group of units, so when you walk from one room to another, there is no difference in what’s playing.

There’s a Sonos “controller” application that you can install on any platform (Android, iOS, Mac OS X, Windows), that allows you to group units together, and play different audio sources on different groups of speakers. The Sonos application for Mac OS X looks really great, and is a consistent look and feel with the Windows and Android versions of the app. If you’re an owner of Sonos devices, then I’d strongly encourage you to check out the Mac OS X version of the app.

One of the great things about the Mac OS X platform is the ability to use gestures on the built-in trackpad, or if you’re on a desktop, the external Magic Trackpad 2.

Three Fingers Swipe Up

If you swipe up with three fingers, on the trackpad, you can easily access Mission Control, which gives you an overview of all the windows that are currently open on your computer.

Three Finger + Thumb Swipe Out

If you take three or four fingers, and place them onto the trackpad, and then swipe your thumb towards them, or away from them, you can reveal the desktop or open Launchpad.

Invoke Mac OS X Spotlight

The most commonly used keyboard shortcut in my Mac OS X experience is the COMMAND + SPACE shortcut. This shortcut launches Spotlight, which helps you find pretty much anything on your Mac, including applications, files, folders, websites, preferences, and so on. I use this shortcut primarily to: launch applications, switch between running applications, and find files. There are some useful filters, such as the “kind” filter, which allows you to search for a specific type of item in Spotlight.

If you’re diligent about tagging your files, you can use the tag:<tagname> filter to find relevant files! Using this technique can really help you filter down to exactly what you’re looking for.

Spotlight’s other supported “kinds” are:

• email
• presentations

• contacts

Menu Option Search

One of the most useful keyboard shortcuts I have come across in Mac OS X is the COMMAND + ? shortcut. You really have to press COMMAND + SHIFT + ? in order to invoke it, since the forward slash key requires the SHIFT key to activate the question mark. What this shortcut does is awesome though. It immediately jumps you to the Help menu in the current application. You can simply start typing a menu option in any of the menus, and when you use the arrow keys to navigate to the one you want, it shows you: 1) where in the menu the option is, 2) the keyboard shortcut for the menu option (if applicable), and 3) an arrow that points to the menu option. How freaking awesome is that?

Check out the following example of how this shortcut works. In the screenshot below, I’m currently using Google Chrome. I want to know how to open the Google Chrome Bookmark Manager using a keyboard shortcut. So I resort to my trusty COMMAND + ? shortcut, start typing a few letters of the menu option I’m looking for, use the down arrow key a few times, to find the correct one, and voila! Mac OS X points me to the menu option that I want.

The key thing to remember about this keyboard shortcut is the element of discoverability. I know what I want, but I don’t know where it is. This shortcut avoids the need to “hunt and peck” through the menus until you find what you want. It doesn’t matter how obscure the menu option is, or how deep it is buried in the menu system. All you need to remember is a few, key letters of the option that you’re looking for!

If you want to truly harness the power of your system, regardless of whether it’s Windows, Mac, or Linux, you will need to learn the command line. On the Windows platform, PowerShell is the go-to automation language, but on Mac, the Bourne Again SHell (Bash) is the default shell. Unlike PowerShell’s integration with .NET and ability to expose modules, Bash relies on external utilities to gain its power.

Command Line Utilities

Homebrew

The Homebrew project is a Mac OS X command line tool that enables you to easily install command line utilities. It is an essential tool to enable rapid installation of other common tools. Each application package is called a formula which is essentially a wrapper around a Ruby script that automates the installation of the package. There are a few thousand packages available in the repository currently. If you want to browse the repository via a graphical interface, you can visit the website Braumeister.org.

To search for packages, simply type brew search <searchterm>.

ScreenResolution

Although the ScreenResolution project doesn’t have a fancy name, it is certainly self-descriptive. This utility enables you to manipulate your Mac’s screen configuration from the command line. Best of all, this project is easily available via Homebrew. Once you’ve got Homebrew installed, simply type brew install screenresolution to grab it!

This utility has three, simple commands: get, list, and set.

If you need to automate switching between screen resolutions, this tool might just help you out!

jsawk

If you’re a systems administrator or software developer who frequently works with REST APIs, you might benefit from using the jsawk utility. This allows you to take JSON output from a command line utility, and parse / manipulate it using in-line JavaScript. There’s a very similar utility out there called jq, which I’ve discovered is actually much easier to use, and offers more comprehensive functionality than jsawk.

Oneroom Mac Os Update

Autojump

If you’re a heavy command line user, you will definitely want to be familiar with Autojump. It is awesome. To install Autojump on Mac OS X, you can easily use the popular package manager Homebrew.

Autojump keeps a history of your most commonly used directory paths, and allows you to rapidly jump between them, without having to type the full path to them. That last bit is absolutely golden. Making human-computer interaction simple and friction-free is essential to enabling productivity.

As long as you can remember a small, unique part of a directory path that you want to navigate to, Autojump will find it for you, and navigate to it in your terminal session. Another great feature of Autojump is that you can open a Mac OS X Finder window, with the specified path open, instead of jumping to the path in your terminal. To do this, use the jo <partialpath> shortcut.

Underscore

If you’re accustomed to working with JSON data, you might want to take a look at Underscore.

Defaults

Yes, although it has a generic name, defaults is actually a Mac OS X command line utility. This utility allows you to read and change settings within Mac OS X that are sometimes hidden from obvious end user view, which is especially very helpful for configuration automation.

Inside the defaults system, there are domains. Each domain corresponds to an application, more or less, and contains a series of keys and their corresponding values. The key-value pairs are read and updated by Mac OS X applications, as you use them. That’s pretty much all there is to it, from an architectural perspective.

That’s all great, but how do you know what domains and keys to use? You can use the defaults domains command, to enumerate a list of all the supported domains on your system. This list could change as you install and remove applications from your Mac. If you want to parse the output and get one domain / application per line, then you can use this command:

Once you’ve found a domain that you want to read or write a setting (key) to, you can use the defaults read <domain> command to read the entire list of settings. For example, run this command to view the stored settings for the build-in PhotoBooth application.

Although the output might look a bit cryptic, try to ignore the syntactical details, and focus on the key-value pairs. There is a setting called NSNavLastRootDirectory, which stores the last location that the filesystem browser was in. Now, open up Photo Booth, take a photo, then export it to a different directory, and then re-run the above command. You’ll notice that the value of the NSNavLastRootDirectory has changed. Armed with this knowledge, we now understand that we can change the default directory that the PhotoBooth application points to, when you export a file. Although this may not seem very useful initially, just think about all the different settings in your other programs that you might want to update, using this simple defaults command.

Operating System

Default Programs

Sometimes your computer will have more than one program installed on it, that can interpret a particular type of file. For example, an image file (JPEG, PNG, etc.) might open with both Photos and Photoscape. If you want to change the default program that a file opens with, you can follow these steps:

Oneroom Mac Os X

1. Locate the file in Finder.
2. Select the file by clicking on it.
3. Press COMMAND + I to invoke Get Info.
4. Find and expand the Open With section.
5. Select a different app from the drop-down combo box.
6. Click the Change All button.

Security – Firewall

In today’s day and age, information security is critical to keeping your personal information safe and away from malicious attackers. There have been many notable hacks on large companies, reported in the news, who have dedicated security teams. Individuals are no exception to the rule. If you haven’t properly secured your systems, then you are at risk for data leakage, which could be catastrophic on your finances, your relationships, and much more.

Mac OS X has a built-in software firewall that, for me, was disabled out of the box. You can easily enable the software firewall using these steps:

1. Open Spotlight by pressing COMMAND + SPACEBAR.
2. Type “security” and launch the Security & Privacy application.
3. Click on the Firewall tab.
4. Click the Lock icon on the lower-left, and type your password.
5. Click the Turn On Firewall button.

Once you’ve switched on the Mac OS X Firewall, you can click the Firewall Options button and enable connectivity for each application that’s installed on your system. Check out the screenshot below for details. If you want to disable other people from “pinging” your system, you can check the box called Enable Stealth Mode.

Security – Disk Encryption

Mac OS X supports native disk encryption, so you don’t need to necessarily purchase a third-party solution for this! Essentially what this means is that, if someone steals your Macbook Pro, they won’t be able to detach the internal disk, connect it to their system, and read the data off of it.
