Got the following error
The path /System/Installation/Packages/OSInstall.mpkg appears to be missing or damaged
while upgrading Mac Mini (Late 2012) to High Sierra. The only option on the screen is to restart, after which the same error pops up. Tried some suggestions from google search and none of it is working
- Tried booting to recovery and using disk utility to repair/firstaid but disk utility is struck in discovering state spinner for one hour
- Using terminal in recovery mode to check the disk and repair permissions and SMART status all are reported fine
- Tried diagnostics and it reported all good
- Internet recovery stuck at globe 3:30 remaining time for past 5 hours
- Tried booting to safe mode which is stuck at apple logo for past 7 hours
What is the next setup in this case, I have Time Machine backup but it was 1 week old and there are some important unbacked files that I cannot afford to lose
