After downloading the new macOS for my MacBook pro (mid-2012) with HDD, the computer restarted but continues to fail during the installation. The error I keep getting is com.apple.DiskManagement error 0. I completed a disk repair but no errors popped up there, so I assume nothing is wrong with the drive. I tried to reinstall macOS from recovery mode, but I continue getting this same error. Does anybody know how to fix this problem?
yes, i had the same problem with a macbookpro8.2 early 2011. i finally installed it with a bootable usbstick. And i formated the ssd with the old os. here is a workaround from apple https://support.apple.com/en-us/HT201372
I had the same issue. It was two long days for me, but the solution was always there.
- You have to go to internet recovery mode with Alt + CMD + Shift + R (all of them).
- You reinstall the OS that came with your Mac (you won't lose your data)
- After you have installed the OS, delete everything related to the previous install (I had to go to the root folder and delete and installation folder)
- Download again Mac OS High Sierra and continue with the steps for the installation.
It took a couple of hours (I have a 10 mb bandwidth connection)
Hope it will help for some of you.
