@rkelegha1 If you have a deferral in place for minor updates you may be running into the problem where Macs are seeing the special build of the 13.4.1 update that's only for the mid-2023 Macs. Remove the deferral and they should get the correct update.

Thanks @sdagley  .. We did have a deferral in place for 13.4.0 upgrade but we are no doing anything for 13.4.1 .. The mac that are seeing the issues are 14" M1 2021

On the chance you aren't doing the same we always recommend users restart immediately prior to attempting a macOS update because our experience has been the longer it's been since a restart the less likely it is the update will be successful.

In general, we have had a lot of problems with OS upgrades via Jamf. In short, they're unreliable. They work for a number of machines but not all. We have tried to do it via Software Upgrade, but the most consistent way for us has been to create a group with the machines we want to target. Then we use the Action function > Send Remote Commands > Update OS version. It gives you the option to specify a version of the OS, as well as whether or not you want the update package to just download to the endpoint, or download & install. If your users are anything like ours I recommend the latter, with plenty of forewarning. 

Also, I'm not sure if this method works for machines that have been manually enrolled. 

Thanks for coming back to me ! I think I have a game plan now ...

One Last questions -- I cant remember but... If there a terminal command or a way that I can just download the 13.4.1 patch on a system? Instead of caching the full installer? ..

I'm not sure you can grab a patch, I don't think macOS works that way. This is the command to grab the full installer for that version:
