Can't seem to find anything online for this error. I've initiated an install of High Sierra Beta 1 and I get this:
"macOS could not be installed on your computer
The operation couldn't be completed (com.apple.DiskManagement error 0.)
Quit the installer to restart your computer and try again."
I have done the follow and all lead back to the same error:
- Restarted
- Reset PRAM & SMC
- Created a bootable USB Beta Install Drive and held "OPTION" on boot to select it as installer
- Opened Disk Utility and checked HDD with First Aid, zero problems and was given green tick
- Made sure no peripherals are connected besides keyboard (mouse is Bluetooth)
- Tried booting with BIOS visible but it refuses to display
This error occurs within 5 minutes of starting the install.
I'm upgrading from macOS Sierra. Valid developer account.
Computer: iMac, 32GB RAM, Late 2012 model (I think).
