Updating macOS with Managed Software Center

LSA Mac computers on an Operating System 10.13 and older need to be updated to 10.14 (Mojave), 10.15 (Catalina), or 11.0 (Big Sur) for security of the computer and the University of Michigan. Keeping operating systems and software up to date is a shared security responsibility that all faculty, researchers, staff, and students using U-M computers are responsible to comply with per the U-M Information Security SPG 601.27 and Responsibilities & Expectations for Self-Managing U-M Devices.

Procedure

Prior to installing the new OS

• Install all pending updates available in the Managed Software Center.
   Tip: Verify that you have opened the Managed Software Center and not the App Store.
• Plug in your computer to a power source.
• Connect your computer to a wired Internet network (recommended).
• Verify your hard drive has 50GB of free space available. To view the available free space on your computer, click the Apple menu (top-left) and select About this Mac. Then, click the Storage tab in the window that displays.
• Allow enough time for the update. It is recommended you set aside at least one hour for the installation to run.
• Backup your data! With any update, there is a small risk of data loss so please verify you have a backup of your data. Check our File Storage web page for a list of supported storage solutions available to you. For help with this, contact LSA Technology Services.
