macOS update failed, can't boot into macOS anymore












1















I tried to update macOS Mojaveto. The update seems to have failed and messed up the boot loader.
When I start with option pressed, I can only select the bootcamp partition and two drives that are just called efi. They all start windows though.



bless --info


shows



... Blessed System File is .../com.apple.installer/boot.efi
... Blessed System Folder is .../com.apple.installer


(... omitted by me). I can't change the startup disk to macOS though, it fails with:



Running bless to place boot files failed


the system.log ends with



Installer Progress: Status is "Restarting"
...
com.apple.xpc.launchd.domain.system: committing to system shutdown
assertion failed: 18A391: launchd + 142080 ...: 0x16


How can I fix this, or get more information on what happened?

  • The bless command is useless when it comes to APFS booting.

  • @DavidAnderson as a way to fix it or useless in the boot process? To me it looks like it is stuck in the update, pointing to .../com.apple.installer/boot.efi

  • It looks to me that you have run out of space in the APFS container. From your posted output, disk3 is 1.8 TB in size, but this is composed of disk0s2 and disk1s2. The sum of these two is 1.72111 TB which probably means the displayed size of disk3 was rounded up to get to 1.8 TB. The "Macintosh HD" volume (disk3s1) is 1.7 TB which could mean you are out of space. So, if you did get the installer up and running again, the result would probably be another crash.

  • FYI, @Geoff Nixon pointed out in a comment to a different question that systemsetup is a replacement for the bless command. Some useful flags would be -getstartupdisk, -liststartupdisks and -setstartupdisk.

  • It looks to me that you have run out of space in the APFS container. From your posted output, disk3 is 1.8 TB in size, but this is composed of disk0s2 and disk1s2. The sum of these two is 1.72111 TB which probably means the displayed size of disk3 was rounded up to get to 1.8 TB. The "Macintosh HD" volume (disk3s1) is 1.7 TB which could mean you are out of space. So, if you did get the installer up and running again, the result would probably be another crash.

You might try to reinstall OSX. To do that power off mac and power on, then click ⌘+R for reinstall current installed version of OSX or Option+⌘+R latest macOS compatible with your Mac just after power on and click it until Apple logo appears.

  • Did you tried to fix disk with Disk Utility? If you can enter into Recovery mode then enter to Disk utility and try to fix disk. Here is a detailed guide: osxdaily.com/2012/02/08/repair-boot-disk-mac-os-x-disk-utilit

  • Did you tried to fix disk with Disk Utility? If you can enter into Recovery mode then enter to Disk utility and try to fix disk. Here is a detailed guide: osxdaily.com/2012/02/08/repair-boot-disk-mac-os-x-disk-utilit
