    Hi Coolabah1au,
     

    Thank you for visiting Apple Support Communities. 
     

    If your Mac doesn't start up after upgrading to El Capitan, first try safe mode--Try safe mode if your Mac doesn't finish starting up.
     

    Follow these steps to start up into safe mode.

    1. Start or restart your Mac. 
    2. Immediately after you hear the startup sound, press and hold the Shift key.
    3. Release the Shift key when you see the Apple logo appear on the screen.

    After the Apple logo appears, it might take longer than usual to reach the login screen or your desktop. This is because your Mac performs a directory check of your startup disk as part of safe mode.

    To leave safe mode, restart your computer without pressing any keys during startup.

    If you don't hear a startup chime after pressing the power key, see what to do if your Mac won't turn on.


    If it doesn't start up in safe mode either, try starting up to OS X Recovery--OS X: About OS X Recovery.
     

    From OS X Recovery you can verify/repair your hard drive using the First Aid option in Disk Utility. If Disk Utility reports that your hard drive is ok, try reinstalling OS X next--How to reinstall OS X on your Mac.

     

    Sincerely.
