Updating mac os 10 4
Restarting my Air Port Extreme Base Station didn’t seem to help, so I restarted the Mac.Instead of booting normally, I ended up at a screen containing only an Installation Log window and an error dialog saying “The mac OS installation couldn’t be completed.” That was confusing since I hadn’t asked the App Store app to install mac OS 10.13.4.I know for certain that it was running 10.13.3, and I explicitly did not ask for 10.13.4 to be installed — I just wanted a quick restart to clear up the performance problems.Shockingly, when the Mac Book Air rebooted, it showed the same Installation Log screen and error.However, clicking the Restart button just brought up the screen and error dialog again.I looked through the log and saved a copy, but none of the errors looked all that problematic.Still no joy, and disk utility is now reporting lots of 'invalid internal_flags'. Finally I restored again and I'm sticking with 10.13.3. warning: inode_val: object (oid 0x5edb): invalid internal_flags (0x48000) warning: inode_val: object (oid 0x5edb): invalid pad2 (0x2a) .
Once First Aid completed the pass on the drive, I simply rebooted and the OS loaded successfully. I was able to boot to Safe Mode (hold Shift during power up) and then restart normally into 10.13.3. I had the same with the previous update, but didn't learn my lesson. However, regretfully my most recent time machine backup was 2 weeks old (I was traveling), meaning I lost 14 days of work.So, since my drive appears to be intact (I used Terminal to browse my data), is it possible to undo the update or reinstall mac OS High Sierra and have the system work as it was before the update (apps and data still accessible)?Note, I use Time Machine backups, and I have a 2TB drive with about 40% free space. Is there a way to recover the system to the Time Machine snapshot taken before each update? Since posting this, Apple called me back and they said that I should be able to reinstall mac OS Sierra without formatting the drive and I should be back to the state I was before the failure.Stack Exchange network consists of 175 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers.Visit Stack Exchange This morning I updated mac OS High Sierra from 10.13.3 to 10.13.4.
