12.4 Update Help!!!

[JG602]

Hello, just got a new to me 2019 16" i9 MacBook Pro. It had 12.0.1 installed when I got it. Downloaded some apps, office, pages, etc. When I went to update to 12.4 it would download the 5GB file, start preparing the update, then soon after give an error saying the updated failed to prepare and to try again. I tried a few more times with the same results. I then booted in safe mode and tried installing it that way but same issue arose.

Please help! Not sure what to do next.

Thank you

Forgot to add. Base model i9 MacBook. Has 1TB drive basically free minus a few apps.

Reboot, Command+R and see if re-installing will pull the 12.4

Sorry I forgot to mention, I did reboot and tried again, same issue.

Did you format everything?

 

[JG602]

I did not format anything.

Sorry I think I misunderstood. You're saying to erase everything and do a clean install in Disk Utility?

Yeah, I'd give it a try.

Do you have another system that is working correctly on 12.4?

 

[JG602]

I do.

 

[MarineBand5524]

I do.

The only thing else I'd say to try would be to Target mode that mac and install it?

Unfamiliar with that. I’ll have to look into it

I'd try the format option first and really do a clean install, it should work.

I would create a bootable 12.4 USB drive and reformat and do a clean install of 12.4 off the USB drive.

Boot from an external drive with 12.4 and just do a "Reinstall" of Monterey. It will install an updated copy of macOS over the previous version without actually affecting any of your apps, settings, accounts, or files.

I erased the drive and reInstalled and that worked!

I erased the drive and reInstalled and that worked!

OUTSTANDING!

Glad to hear it.

I'm glad it worked out for you. This method has always worked for me when all else fails.
