I Have downloaded sierra and attempted a restart. however, I have a screen up now which states macOS could not install. " File statement verify or repair failed. Quit the installer to restart your computer and try again." I have done thisand it comes back to the same screen. What can I do?
G5, Mac OS X (10.4.11)
Try looking in Applications for Sierra and if it's there double click it. If the problem persists you should first check to see if your computer meets the minimum system requirements. If it meets the minimum system requirements, then it is possible you got corrupt download or you have hardware issues.
UUnfortunately, I can't get to Applications as I appear to be stuck in a loop. I can'restart my computer without installing Sierra which won't install for the reasons above. Does this indicate a hardware problem?
I have no idea what happened, shut it down and try to restart in the Recovery Partition and then reinstall OS X . You do that by holding down Command + R
I Have the same problem. I tried to reinstall OS X and there is an error. I tried to get into safe mode as well by pressing shift at start up and it just shuts off.
I have exactly the same issue. Apple support have just said my disc is probably broken as apparently there may be things that were not being used before the update that now are and the update has merely highlighted failing areas on the computer.
In other words you're bricked
I followed the advice about pressing command R and the computer eventually rebooted Sierra has no installed. Thanks for all of your help.
I will try that then. Thanks
I had the same problem but resolved it...I could never get out of the reboot loop without doing a full restore from a TimeMachine backup.
1) Booted into Recovery mode (Command+R)
2) Restored from TimeMachine backup back to El Capitain.
3) I did disk check with DiskUtil and fsck but neither found any problems.
4) Redownloaded Sierra install files and the install went fine after that.
I had the same problem also - fortunately I did time machine today! I may forget Sierra
You obviously did something very very wrong and destroyed the logic board. I suspect the entire machine is now worthless. Get a new Mac and try the installation the correct way.
That's quite likely an over-reaction. What is more likely is this is what happens when the Sierra download is corrupted and there is just no way to recover without restoring from back up first and redownloading.
Sierra won't install: " file system verify or repair failed". What can I do to restart my computer?
