Update a Mac Operating System

For security of the computer and the University of Michigan, LSA Mac computers need to be updated to the most recent versions of 11 (Big Sur), 12 (Monterey), or 13 (Ventura). 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

 Note: macOS updates require an administrator account to upgrade.
In the past, macOS updates did not require administrator privileges, however, Apple has now added this requirement to all supported operating systems. How to determine if you have administrator privileges:
1. Open System Preferences
2. In the System Preferences window, click on the Users & Groups icon
3. On the left side of the window that opens, locate your account name in the list
- If the word Admin is immediately below your account name, then you are an administrator on this machine
​​​​​​​- If the word Standard is there, then you are not an administrator and your account cannot be used to install software or make administrative changes
If you do not have administrator privileges on your Mac device, please contact the LSA Technology Services support team when you are ready to upgrade to and they will be able to remotely enter administrator credentials to initiate the process.

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.
