Jun 14, 2013 Such boot drives are easy to create on your own, here are instructions for making boot disks for OS X 10.9, OS X 10.8, and OS X 10.7. For older Macs running prior versions of Mac OS X, typically anything running OS X 10.6 or earlier will have a SuperDrive, and thus shipped with a bootable DVD that can serve this same purpose.

I've successfully installed the High Sierra GM candidate on my MacBook Pro.

I've spent the past few hours trying to get it to install onto my Mac Mini (Late 2014). Currently running Sierra.
Chevrolet optra magnum 2016 service manual. When I run the installer, it reboots, starts to install, then says 'Unable to unmount volume for repair'.
If I boot into Recovery, then run disk utility, I get a similar error. If I bring up a terminal, then 'diskutil unmount' the drive, it says 'Volume Macintosh HD on diskX failed to unmount: dissented by PID=0 (kernel)'. This is from the Recovery partition, so I'm not actively booted from 'Macintosh HD'.

I ran 'diskutil unmount force' on the partition, then I was able to run Disk Utility's 'First Aid'. Everything seemed OK. I still couldn't install High Sierra (same error).
I then created a High Sierra installer on an SD card, and booted from it (held Option while booting). Again, when installing macOS, I get the 'Unable to unmount the volume for repair' error.
If (while booted from the SD card) I bring up a terminal and 'diskutil unmount force', the installer doesn't show 'Macintosh HD' as an option (expected).
If I run 'diskutil mount readOnly ..', then run the installer, it sees the disk - but fails (because it's readonly). When it's mounted readonly, 'diskutil unmount' (without force) works fine.
If I run 'diskutil mount ..', then immediately try 'diskutil unmount' (without 'force'), it fails with the same 'dissented by PID=0 (kernel)' error.
Why is the kernel mounting 'Macintosh HD' (even when I'm booted from external media) and keeping it 'locked'? Is there any way to fix this?
I've also tried 'csrutil disable' to disable the System Integrety protection stuff. No difference.
