Mac OS Applications

How do we install an application on a Mac OS?

  • DMG.  A DMG is a mountable disk image.  Once you have the DMG, double-click on it to mount it.  The image will show an App icon.  You can click on the App to run it.  You can also drag the App to your Applications folder.

  • PKG.  A PKG file is a package.  You can run the package file to install the program.

  • APP.  An APP file is a package bundle.  You can double-click on the APP file to run the program (without installing it).

  • App Store.  You can open the App store and search for the app that you want.  You must be logged in with your Apple ID.  When you find the app that you want, choose to install it.  The App store will automatically download it and install it on your computer.

You can uninstall any application by going to the Applications folder and deleting the application.

Apple ID and Corporate Restrictions

A business can issue corporate Apple IDs to its employees.  When you sign in to a device with your corporate Apple ID, your administrator will have some control over your device. 

Apple devices and IDs are not as easy to manage as Windows devices and IDs.  I do not recommend using Apple devices in your organization. 

You can link an Apple ID to Microsoft Azure Active Directory, but this is a difficult process.  When you establish the link, a user can sign in to their Mac or iPad with their Microsoft account.

An administrator can automatically deploy applications on any managed device.  When a user is signed in with a corporate Apple ID, they can’t use any of the following

  • App Store

  • iTunes Store

  • Apple Pay

  • Home Kit

  • iCloud Mail

  • FaceTime

  • iMessage

Best Practices for a Mac
