10.13.2 upgrade failure

Hi Crabby,

macOS High Sierra 10.13.2. update has been a headache for many of us...

On my side either I couldn't install and when I eventually managed to install it, it was not with the App Store updates but with the combo update, maybe you should try this:

• Reboot with the option key and get out of the macOS install drive and restart with your normal Mac drive
• Check on App Store update if the 10.13.2 update has been installed
• If not and the update is not present on the available update download then download the combo update 10.13.2
• 10.13.2 Combo Update
• Make sure you have a full backup, ideally time machine, as if there is anything going wrong it is the safest way to reinstall it from the recovery!
• Update

And maybe with a bit of luck half an hour you should be back on track...

Let me know if it worked...

Good luck!

Any way to find out what is causing it to fail?

The only practicable way is to revert your system to a known supported configuration. Samsung SSDs (for example) are notoriously problematic. SSDs from OWC / MacSales (for example) are known to work.

Apple does not support replacing a Mini's internal storage, and 16 GB may not be a supported configuration. To determine the memory specifications for your particular model, please refer to the Memory Upgrade Instructions in About This Mac > Memory.

Or should I do a complete recovery from the time machine and run the upgrade again and hope it works?

Short of replacing the suspect components that's what I'd do.
