List of macOS Terminal commands

This article lists out different macOS terminal commands you might encounter. You can use this list as a starting point in your search for a command to perform a specific task. This list is by no means exhaustive.

Basic terminal commands are not listed here. Some of them are listed in the following Terminal command articles.
Terminal Commands – Basic
Terminal Commands – Part 2
Terminal Commands – Part 3

Many of the commands have also been used in the article I wrote some time back. You can have a look at the scripts to see some of the commands being used.

To get more information about the commands simply run the following command from within Terminal Application. For example, to view the manual page for tmutil simply type:

man tmutil

For fdesetup

man fdesetup
Here is a nice command to quickly open the man page in the Preview App.
man -t tmutil | open -f -a /System/Applications/Preview.app

Note

  • This is not a complete list of commands
  • Some commands are available through the macOS Recovery Volume only
  • Some commands required other resources such as the OS installer
  • Some commands are available with certain versions of the OS only

Please read the documentation for more details. Use the commands with care. Improper use of commands may result in loss of data or damage to the computer.

Screen and Audio recording on macOS & iOS

In this article we are going to look at how we can use the built in Application: QuickTime to record a screen or a movie. In fact, the videos that you are about to see in the article below were created using QuickTime.

A good reason to record the activity on the screen would be to create a visual step by step guide which can be distributed to employees in the organisation. For example, you can create a video to show employees how they can sign into their company’s email account and access it from their iPhone or Mac.

Recording your Mac’s screen

Follow the steps given below to record your Mac’s screen:

  1. Open QuickTime Player
  2. Click on File > New Screen RecordingScreen Shot 2018-01-24 at 4.46.22 PM
  3. You should see the window popping up.
  4. From the drop down next to the Record button select the audio input & whether mouse clicks should be shown.Screen Shot 2018-01-24 at 4.47.29 PM
  5. Click on the Record Button. You should see a dialog asking you whether you want to record a small area or a full screen.Screen Shot 2018-01-24 at 4.47.52 PM
  6. The recording starts once the stop button in the menu bar becomes dark.
  7. Click on the stop button to stop the recording.

  8. Save the file that was created.

Recording your iPhone/iPad Screen

(Mirroring your iPhone Screen on the Projector)

The process of recording the iPhone/iPad screen is quite similar to recording your computer’s screen. The key thing to remember is to connect your iPhone/iPad to the Mac with the lightning cable.

Follow the steps given below to record your iPhone/iPad screen:

  1. Open QuickTime Player
  2. Click on File > New Movie Recording
  3. You should see the window popping up.
  4. From the drop down next to the Record button select the audio input & whether mouse clicks should be shown. The difference now is the fact that you get an extra option to choose the source.

Here is a quick video on how to perform the different tasks that we have seen above.

Buyers Guide for macOS & iOS in the Enterprise

This article is more of a productivity article aimed at getting first time users up and running quickly on their Mac, iPhones or iPads. Anyone looking to buy one of these products or Tech Support teams that help employees with their computers would find this article helpful. The thoughts shared here are personal, readers are welcome to share their own thoughts and experiences.

The article is not a comprehensive guide. Its aim is to give potential users some idea as to how the devices can be used in their work environment. Specifically from an Application perspective.

Macintosh

macFamily


Which one to buy?

This depends on how the device is going to be used. Here are 3 general classifications:

Basic Usage

Basic usage would mean simple day to day tasks. These are the tasks that would qualify for:

  • Checking emails
  • Browsing the web
  • Social Media
  • Listening to Music
  • Watching Movies
  • Composing letters
  • Preparing Presentations & running presentations
  • Note taking

In such a case you may want to consider buying a MacBook or a MacBook Air. If portability is not required then a Mac Mini would also do.

At entry level configurations these devices would do the job very well.

Intermediate Usage

If the tasks being performed are a little more demanding then you may want to consider higher configuration devices. Again in most cases the  MacBook or a MacBook Air would do. If portability is not required then a Mac Mini would also do. In all these cases consider one with slightly higher configuration.

For situations where the compute power is important you may even consider the MacBook Pro. For example, if there are programmers who need to work with a high configuration Mac and they need portability, then you can consider the MacBook Pro.

Pro Usage

This indicates that the tasks being performed are very compute intensive. These are some of the job profiles which may demand compute intensive resources:

  • Programmers
  • Video Editors
  • Audio Editors
  • Post Production Teams
  • Marketing & Creative Teams
  • Scientific Research

For such situations the higher end desktops & MacBook Pros would be required. So the iMac or the highest configuration Mac Mini, or the 15″ MacBook Pro would be best suited for such environments.

In some situations even more powerful computers would be required. The iMac Pro & Mac Pro should then be considered.


Built In Applications that might be useful

Productivity Tools

There are 3 applications which are a part of the suite called iWork that are very useful in organisations.

  • PAGES: Built in word processing application. You can easily created documents, letters, reports and even have them exported in Microsoft Office compatible format.
  • KEYNOTE: Built in presentation applications. Enables you to create powerful presentations from scratch. Like Pages it is possible to create presentations that are compatible with PowerPoint.
  • NUMBERS: Built in spreadsheet application. Enables you to quickly create spreadsheets and export them to Excel if needed.

The other advantage is the fact that these applications are also accessible from the cloud. Tight integration with iCloud means that you can make changes to documents from your Mac, iPhone, iPad, or iCloud.com.

Creative Tools

There are 2 applications which are available for creative purpose. These might be handy for people working in the creative departments.

  • IMOVIE: Quick create movies using videos, audios and photos that you have.
  • GARAGEBAND: A simple Music creation application that comes with a library of different instruments.

Popular Third Party Applications

These are just some of the applications.

  • Record a quick movie using QuickTime
  • Automate Tasks & create workflows using Automator
  • Encrypt Data using FileVault
  • Show your iPhone/iPad screen on a projector using QuickTime on Mac
  • Backup data using Time Machine

iPhone/iPad

iosFamily


Which one to buy?

The decision on whether to buy the iPhone &/or the iPad depends a lot on what you intend to use it for. As such the major differences between the 2 devices are:

  • iPads tend to have larger screens
  • iPhone has cellular communication capability
  • iPhones are more portable as compared to iPads
  • iPads are better suited for long duration usage
  • iPads tend to be higher powered devices

While it appears that iPads are better than iPhones, that is not necessarily the case. iPhones being smaller and more compact have many advantages too.

Ideally speaking having both, an iPhone and an iPad, is the best thing to do.

To make a decision use the task list below to help find out if you need an iPhone or an iPad or both.

Note, even though I mention that the tasks can be performed easily on an iPhone, many of the tasks can also be done very easily on the iPad. The point is to illustrate ease of use in situations where you have to perform tasks with a single hand or when you are on the move.

Tasks easily performed on an iPhone

  • Making calls
  • Messaging
  • Scheduling activities such as: Reminders, Appointments, Events
  • Taking Photos & Videos
  • Emails
  • Banking Transactions
  • Finding Transit Directions
  • Finding a Taxi
  • Making E-Payments

Tasks easily performed on the iPad

  • Writing letters & blogs
  • Creating Presentations
  • Working with spreadsheets
  • Creating posters, flyers
  • Working with business applications
  • Content creation

If you do a mixture of tasks from both the lists then getting both an iPhone as well as an iPad is a good idea.

A thing to keep in mind is that the Pro version of the iPad also has a nice keyboard accessory as well as the  Pencil available. These 2 products make the whole experience so much better.

Screen size consideration

iPhone and iPad screen sizes vary quite a bit. Here are some tips on the tasks which can be best performed on specific screen sizes.

Creative Work

Generally speaking, creative tasks require a large screensize. So for an iPhone the smallest screen you should have is 4.7″. Similarly for the iPad the smallest screen you should have is the  9.7″.

Documents, letters, spreadsheets

These tasks are better performed on the iPads as such you can go for any screen size in them. Of the lot, its a lot easier to create documents and letters on the phone than spreadsheets. Again, for phones one should the larger the screen size the better.

Presentations

Like documents and spreadsheets presentations are a lot easier to create on the iPad. They can also be created from the phones. The larger the phone the better.

Messaging & Communication

This is one aspect where the screen size is not so much of an issue. In fact, some users may find the smaller screen size a lot better. Typically, the iPhone is a much better device than the iPad for this.

Productivity & General Tasks

This includes calling taxis, ordering food, taking notes, control keynote presentations, setting up appointments and reminders. These tasks are also best performed on iPhones. They can be done well with the iPad too.


Built In Applications that might be useful

Productivity Tools

There are 3 applications which are a part of the suite called iWork that are very useful in organisations.

Some tasks that can be done with built in Applications

  • Scanning Documents using Notes
  • Recording Voice Memos
  • Control HomeKit devices
  • Edit PDFs through iBooks
  • Create PDF documents through pages & then edit the PDFs either through iBooks or markup utilities
  • Record and Edit videos using the camera & iMovie

Useful iPad Accessories

 TV

There are a few things that can be done with the  TV. It can be used to mirror both macOS & iOS Devices. In which case apps such as Reflector are not really required.

It is very easy to setup and use. This can make projecting both the iPad screen as well as the iOS Screen very easy & it allows you to move across the room as you are not physically wired to the projector.

Final Word

As we can see there are a wide variety of apps available both for macOS & iOS. These include built in apps as well as Third party apps. The community of developers creating these apps is strong and growing. There are many more apps which can be used for a wide variety of purposes.

This article should give the user a fair idea as to the capabilities of devices such as iPads, MacBooks and the rest of the line up. The good thing is that for enterprise environments its easily possible to create apps that are tailored to the needs of that organisation and this makes the devices much more attractive.

macOS & iOS IT Tool List

This list is based on questions that I have been asked by various IT admins.

It is more of a collection of tools (mainly software, but a few hardware tools too) that Enterprise IT Teams might find useful while supporting/managing Macs & iPhones in the enterprise. Some of the tools are free, while others are paid. Also, it is not necessary that all the tools will be required. Of course, some tools are not meant for troubleshooting but provide a service themselves.

The below list is not an endorsement or recommendation of any of the products mentioned. These are just some of the products I have come across. You may have to do your own research to see which tool fits your organisation’s needs. The author is not responsible for any damages or loss of data that might occur from usage of these tools.

*This list is not a complete list but an ongoing project. Feel free to share your comments on tools that you may have used & I will add them to this list.

Creating multi-OS Install Disk

In this article we are going to look at how to create a multi-OS Install Disk. We are going to look at the example of creating a multi-OS Install Disk for the following versions of the OS:

  • 10.9.1
  • 10.10
  • 10.10.4
  • 10.11.5
  • 10.12
  • 10.12.1
  • 10.12.2
  • 10.12.3

The idea is to have a single disk with multiple versions of the Install Disk on it. The versions should reflect the need of the organisation.

REQUIREMENTS

  1. USB Drive at least 75GB in Size. This depends on the number of Install drives you wish to have. At the very least there should be enough space to create 2 partitions of 8 GB each. 
    While I have mentioned USB drive, it need not be restricted to that interface. You can use Thunderbolt, FireWire or even an SDXC slot for this. Ideally the port should be one that is supported on maximum possible computers.
  2. Install setup for each version of the OS for which you want to create the install disk. The setup must match the version desired.
  3. A Mac running the same major version of the OS. You can only create an install disk for 10.9.x on a Mac running OS X 10.9.x, the same applies for the other versions of the OS.

The process is the same. It’s just that it needs to be repeated.

STEPS

  1. Create 8 partitions on a USB Drive. Assume that the USB Drive is called Recovery Drive. Give the partitions names Partition 1, Partition 2,….
  2. Connect the USB Drive to a Mac running 10.9.1 or later.
  3. Make sure that the OS Installer setup is located in the Applications folder.
  4. Run the following command in the command line.
    sudo /Applications/Install\ OS\ X\ Mavericks.app/Contents/Resources/createinstallmedia --volume /Volumes/Partition\ 1 --applicationpath  /Applications/Install\ OS\ X\ Mavericks.app
  5. Rename the partition as Install disk for OS X 10.9.1, if necessary.
  6. Once completed eject the USB Drive & connect it to a Mac running 10.10
  7. Make sure that the OS Installer setup is located in the Applications folder.
  8. Run the following command in the command line.
    sudo /Applications/Install\ OS\ X\ Yosemite.app/Contents/Resources/createinstallmedia --volume /Volumes/Partition\ 2 --applicationpath  /Applications/Install\ OS\ X\ Yosemite.app
  9. Rename the partition as Install disk for OS X 10.10, if necessary.
  10. Once completed eject the USB Drive & connect it to a Mac running 10.10.4
  11. Make sure that the OS Installer setup is located in the Applications folder.
  12. Run the following command in the command line.
    sudo /Applications/Install\ OS\ X\ Yosemite.app/Contents/Resources/createinstallmedia --volume /Volumes/Partition\ 3 --applicationpath  /Applications/Install\ OS\ X\ Yosemite.app
  13. Rename the partition as Install disk for OS X 10.10.4, if necessary.
  14. Once completed eject the USB Drive & connect it to a Mac running 10.11.5 or later.
  15. Make sure that the OS Installer setup is located in the Applications folder.
  16. Run the following command in the command line.
    sudo /Applications/Install\ OS\ X\ El\ Capitan.app/Contents/Resources/createinstallmedia --volume /Volumes/Partition\ 4 --applicationpath  /Applications/Install\ OS\ X\ El\ Capitan.app
  17. Rename the partition as Install disk for OS X 10.11.5, if necessary.
  18. Once completed eject the USB Drive & connect it to a Mac running 10.12 or later.
  19. Make sure that the OS Installer setup is located in the Applications folder.
  20. Run the following command in the command line.
    sudo /Applications/Install\ macOS\ Sierra.app/Contents/Resources/createinstallmedia --volume /Volumes/Partition\ 5 --applicationpath  /Applications/Install\ macOS\ Sierra.app
  21. Rename the partition as Install disk for OS X 10.12., if necessary.
  22. Once completed eject the USB Drive & connect it to a Mac running 10.12.1 or later.
  23. Make sure that the OS Installer setup is located in the Applications folder.
  24. Run the following command in the command line.
    sudo /Applications/Install\ macOS\ Sierra.app/Contents/Resources/createinstallmedia --volume /Volumes/Partition\ 6 --applicationpath  /Applications/Install\ macOS\ Sierra.app
  25. Rename the partition as Install disk for OS X 10.12.1., if necessary.
  26. Once completed eject the USB Drive & connect it to a Mac running 10.12.2 or later.
  27. Make sure that the OS Installer setup is located in the Applications folder.
  28. Run the following command in the command line.
    sudo /Applications/Install\ macOS\ Sierra.app/Contents/Resources/createinstallmedia --volume /Volumes/Partition\ 7 --applicationpath  /Applications/Install\ macOS\ Sierra.app
  29. Rename the partition as Install disk for OS X 10.12.2, if necessary.
  30. Once completed eject the USB Drive & connect it to a Mac running 10.12.3 or later.
  31. Make sure that the OS Installer setup is located in the Applications folder.
  32. Run the following command in the command line.
    sudo /Applications/Install\ macOS\ Sierra.app/Contents/Resources/createinstallmedia --volume /Volumes/Partition\ 8 --applicationpath  /Applications/Install\ macOS\ Sierra.app
  33. Rename the partition as Install disk for OS X 10.12.3, if necessary.

The commands shown above might be different from what appears on your screen. A lot will depend on what you have named your partitions as, the name you may have given to the OS Installer file, and the location of the OS Installer.

The process of renaming the partitions post creation of the install disk is not necessary, but very useful because that will help you identify the appropriate partition when using the drive.

The above process is very scalable & can be done for even more versions of the OS if required.

OS X and iOS troubleshooters toolkit

This article covers some of the things troubleshooters would need during their everyday work. I’ve also listed links to some products and applications as an example. It is by no means an endorsement of the same.

OS X Install Disk: This is probably one of the most important tool that a troubleshooter must carry around with him/her. Ideally it would be one disk with multiple versions, each corresponding to a specific version of the OS. Exactly how many versions depends on the situation, for example one can have all instances of the present and previous 2 versions of the OS (For example OS X Mavericks 10.9, 10.9.1, 10.9.2, 10.9.3, 10.9.4, 10.9.5 OS X Yosemite 10.10, 10.10.1, 10.10.2, 10.10.3, 10.10.4, 10.10.5 OS X El Capitan 10.11, 10.11.1)

Thunderbolt & FireWire Cables: These come in handy when it comes to transferring data. These cables  are necessary when you wish to  perform target disk mode troubleshooting. Make sure you have the correct version of the cable.

http://www.apple.com/shop/product/MD862LL/A/apple-thunderbolt-cable-05-m

Portable Storage Device: Along with the cables mentioned earlier having a portable storage device with a large capacity is useful. Mainly when it comes to taking a back up. The user may or may not have a storage device available for this. (Ideally, taking a backup of the data should be done by the user on his/her own storage device.)

http://www.lacie.com/as/en/products/mobile-storage/rugged-thunderbolt/

http://www.apple.com/shop/product/HE154VC/A/promise-pegasus2-r8-24tb-8-by-3tb-thunderbolt-2-raid-system

http://www.promise.com/Products/Pegasus

Internet access via USB Dongle: Yet another important tool. Application & OS upgrades require internet access. This will also come in handy when you are trying to perform network troubleshooting. Make sure there is sufficient data available for upload/download. Optionally one can carry multiple Internet dongles from different vendors.

Portable Power Bank: This is more useful for portable devices. Carry one with a large capacity, enough for multiple recharges or charging multiple devices.

Display adapters: Necessary to troubleshoot when the main display isn’t working or to heck the display ports. Carry all combinations HDMI to VGA, MiniDisplay to VGA, MiniDisplay to HDMI, HDMI to HDMI and any others depending on the device to be connected to.

http://www.apple.com/shop/product/MB572Z/B/mini-displayport-to-vga-adapter

Secondary Display: This might not be practical as displays tend to be very large and not necessarily portable. However, one can carry a small pocket projector. A secondary display is always handy as it reduces dependency on the user/client to provide one.

Power adapters: Not strictly required but can come in handy. Useful for checking if the user’s power cord is functioning properly. Make sure you carry all the different versions of the power cords.

Lightning & 30 pin cables: Again not strictly necessary but would be useful for checking if the user’s power cord is functioning properly. Make sure you carry all the different versions of the power cords.

MacBook Pro &/or iPad: Carrying your own Mac & iPhone/iPad is very important. Load these devices with various tools required to diagnose and/or fix issues.
