Hi I left my 2012 imac over night to install Mojave. Came in this morning now it wont start up.
I keep getting the initial start up bar which gets toward the end then gives up and switches the computer off.
Any ideas? thanks

Try booting into the Recovery volume (boot with the Command + R keys held down). If you can select Disk Utility and run First Aid on the boot drive. Try to reboot normally.
If that fails, again boot into the Recovery volume and reinstall the system.
