Minimum supported version of macOS

Tags macOS Apple

Starting December 19, 2020, all Mac computers on the Michigan Tech network must be running High Sierra (10.13.6) or newer as their operating system. The following models are compatible with High Sierra:

  • MacBook (Late 2009 or newer)
  • MacBook Pro (Mid 2010 or newer)
  • MacBook Air (Late 2010 or newer)
  • Mac mini (Mid 2010 or newer)
  • iMac (Late 2009 or newer)
  • Mac Pro (Mid 2010 or newer)

How to determine your Mac’s hardware model

From the Apple Menu, select About This Mac. A window will appear with the name of your operating system, along with a numerical designation. In the example shown below, this computer is running Catalina, version 10.15.6.

If your Mac is not listed above, you will not be able to upgrade it to the minimum requirements. Our procurement staff can help you explore other options. Due to COVID-related delays in purchase times, we recommend that you begin exploring alternatives well before the December date. Call us at 7-1111 or email

If your computer is listed above and has an operating system that is lower than 10.13.6, use the following instructions to upgrade.

Part One: before you upgrade, backup your information

In order to ensure the integrity of any information on your computer prior to upgrades and make sure your important information is kept safe, we recommend that you perform regular backups of your computer and files. 

We recommend the following backup options:

  • Time Machine: This macOS built-in tool takes a complete capture of your computer and copies it to an external drive of your choice. Refer to Apple’s Instructions how to back up your Mac with Time Machine.
  • Google Backup and Sync: With this tool, you can specify which files you’d like copied from your computer to your Google Drive. Learn more at Back up & sync files with Google Drive.
  • File Stream: Google Drive’s File Stream creates a link between folders on your computer and Google Drive, creating a continuous backup of those files. Instructions for use are in the article Use Drive File Stream with work or school.

Part Two: check for 64-bit application compatibility

Before you upgrade, you’ll need to make sure your applications are 64-bit compatible, as 32-bit apps are no longer compatible with macOS. Refer to Apple’s support article on 32-bit app compatibility with macOS High Sierra 10.13.4 and later. If all of your applications are compatible, you may proceed with the Catalina update. 

Part Three: upgrade your OS

You have two options to upgrade. You can either upgrade on your own or have us upgrade it for you.

Do it yourself

  1. Start the Tech Apps application from Launchpad or by selecting from your applications folder.
  2. Under Bookmarks, select Operating System Bases, then choose Install macOS Catalina. *You may see macOS High Sierra or macOS Mojave based on your Mac's hardware.

Have us walk you through the upgrade

Call IT at 7-1111 during normal business hours or email An IT staff member can walk you through the upgrade process. 

Have IT perform the upgrade

If you prefer, you can drop off your computer and we will update it for you. If you choose this option, make sure you’ve first completed parts one and two (backing up files and checking for application compatibility).


If you have any questions about macOS, we can help. Contact IT at or call 7-1111.
