Hello

For those of you using super as any comes across this issue.
We currently rolling out MacOS 15 to our Mac estate


I have seen this message in the logs it doesnt seem to be all machines just some.


Sun Apr 27 06:44:10 M-5ce91eb4f537 super[94775]: Disallowed: The following "over-the-air" macOS major upgrades are available but not allowed:
Sun Apr 27 06:44:10 M-5ce91eb4f537 super[94775]: Disallowed: macOS major upgrade 1 of 1 is: Title:macOS Sequoia 15.4.1,Build:24E263,Version:15.4.1


Depsite my config profile having the write settings for major upgrades



            <key>InstallMacOSMajorUpgrades</key>

	<true/>

	<key>InstallMacOSMajorVersionTarget</key>

	<string>15</string>


The profile seems to be working on 100 of machines just some seem to be having issues. In some cases it seems to resolve itself.

Any idea?

@tdenton A couple of questions come to mind: Do you have any update deferral Configuration Profiles deployed? Do any of these Macs reporting the error have an older full version of the macOS Sequoia installer app downloaded?


Some Macs show a super log error stating macOS 15.4.1 is "disallowed" despite an MDM profile allowing major upgrades to macOS 15.


Possible Causes:



  • MDM profile misapplied or conflicting.

  • MDM deferral policies or restrictions.

  • super bug or misconfiguration.

  • Device-specific issues (disk space, M1/M2, etc.).

  • Network or Apple server issues.


Solutions:



  1. Verify MDM profile: sudo profiles -P -o stdout.

  2. Check for MDM deferral/restriction policies.

  3. Review super logs and update the tool.

  4. Test update availability: softwareupdate -l.

  5. Check disk space and integrity.

  6. Try updating in Safe Mode or manually via installer.

  7. Test Apple server connectivity: ping swscan.apple.com.

  8. Verify bootstrap token: sudo profiles status -type bootstraptoken.


Recommendations:



  • Prioritize macOS 15.4.1 for security fixes.

  • Test on a few affected devices.

  • Contact MDM support if unresolved.

  • Check MacAdmins forums for similar issues.


Provide more details (MDM, super version, Mac models) for tailored help.


Couple of thoughts, only because I ran into this while we are in the early stages other testing and deploying SUPER.


- You don't mention which version of SUPER you're using, but v 5.1.0 (still in beta) specifically calls out support for macOS 15.


- Apple recently released macOS 15.4.1 that resolved a macOS 15.4 update issues (https://support.apple.com/en-us/121011) that "Improves reliability when installing macOS updates".  On the SUPER Slack channel, reports are this fixed an issue some SUPER managed devices were having.

@pbenware1 

We aere using version 5 which I belive is compatablie with macOS 15 I saw the info about the fixes for macOS 15.4.1.
Intrestingly I removed the below from our config profile


   <key>InstallMacOSMajorUpgrades</key>

	<true/>


I then added it to our policy which installs the script it doesnt seem to be doing on the machine I had issues with.

Might look to do some testing with beta if the issues continues.

Have you seen the issues with your own super setup?

@tdenton A couple of questions come to mind: Do you have any update deferral Configuration Profiles deployed? Do any of these Macs reporting the error have an older full version of the macOS Sequoia installer app downloaded?


No update deferral Configuration Profiles deployed and no sign of  older full version of the macOS Sequoia installer either.

I moved  this out of the config profile and into the policy that installs the super script and it doesnt seem to be doing it now.


  <key>InstallMacOSMajorUpgrades</key>

	<true/>
