N-1 OS Version Support Change

Beginning January 1, 2023, Izzy will only provide packages and app updates for Macs running the current and one previous operating system version. This is a change from our previous ā€œn-2ā€ support policy.

What this means: Macs running macOS 11 or under will not be able to download packages from Managed Software Center, including updates to already-installed apps.

  • We already do not deliver packages to Mac OS X 10.14 or older.

  • Apple OS updates, in addition to OS upgraders, will continue to be delivered.

  • Unit IT can see which systems in their inventory are unable to upgrade to macOS 12 (or other versions of macOS) using the ā€œDownload CSVā€ button on their organizationā€™s page in Izzy.

Why this change now: In October 2022, Apple formally announced that they do not patch every security issue in any version of macOS other than the most current. We recognize that moving to an ā€œnā€ support model would be onerous, but we believe going to n-1 will not be a significant problem for most units.

By the numbers: 89% of managed Macs are already running macOS 13 or 12, 25 days after macOS 13 was released to them.
