How can I decrease the OS update duration to be below 10h?
With my Mac Studio M1 Max it is always like this.
- Apple suggests an update of the operation system.
- Download works fine, it installs something then asks for a restart
- The computer does not boot properly
- Unlike windows it does not roll back with the intention to restore the system as it was
- Booting always ends in the recovery frontend (or however it is called in English):
- It says something like "The recovery system has been started as there was an error during installation"
- In this state:
- Restoring from the time machine (Option 1) does not work: It claims that the OS is not installed properly
- Installing the OS (Option 2) does not work, as it will end with exacly the same error message: Just a waste of time
- So the procedure is
- I have to delete the container on the hdd
- Then I have to freshly install Montery (with the image the Mac Studio comes with)
- Then I have to freshly install Ventura on top
- Then I have to restore my system from time machine with the help of the migration assistant (which take a long time)
- The I have to fix various things, e.g. RME Soundcard Setup, Dropbox, ...
- ... ie it takes more than 10 hours.
This happended to me twice
- First time was a minor update of Monterey, I lost some data due to an outdated timemachine backup
- It was my fault to trust the minor update procedure without proper backup
- Second time was just now: The Update from Monterey to Ventura 13.3.1 (a) (22E772610a)
Questions
- Any ideas what's so special about my system, that it always fails to update properly, see system spec below?
- Am I the only one with this issue?
- Into which files should try to take a look prior to wiping the internal ssd, to obtain information helping Apple to make updates executable on my system?
