In Jamf School, We have a Restriction Policy with Software and App updates deferred for 30 days but our staff still has the ability to download Monterey.
I tried creating a Profile Named Block Monterey and in the Safest and Blocklist I added /Applications/Install macOS Monterey.app/Contents/MacOS/InstallAssistant to the Paths to disallowed applications which did not work.
Has anyone had success blocking Monterey using Jamf School?
On macOS Big Sur you can use the new "com.apple.applicationaccess" preference keys to delaying major OS updates for 90 days: set "forceDelayedMajorSoftwareUpdates" to true, set "enforcedSoftwareUpdateMajorOSDeferredInstallDelay" to 90. This works Specifically for 11.3 and onwards clients
Interesting. I checked on our end with a different device than last time and it blocked it successfully. Not sure what else to suggest other than ensuring the profile was installed correctly.
Same here, except set to 90 days. Looking at what vinu posted earlier, software updates must be organized in different categories with different settings. Meaning "major updates" are not managed with that setting.
Just for the sake of clarification. With the Blocklist you're still able to launch the Install macOS Monterey app? The download will not be blocked by it, but running the installer is blocked.
I'm double checking myself and downloading the update on a different device to see if the automatic launch after download is blocked... Previously I was copying the installer to other devices.
I actually tried this workflow on a few more Macs and I was able to download and install Monterey. I do have the Profile to Block Monterey installed on each. I believe the Mac I received there error on was just a problem during the download process since I was able to go back and download and install on the second time. I appreciate your help though but I'll need to find another solution.
