    Hi Rusty_III, 
     

    Thanks for participating in the Apple Support Communities. 
     

    If your MacBook Air doesn't start up after upgrading to El Capitan, try these steps first:
     

    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 El Capitan doesn't start up in safe mode, try starting from OS X Recovery and verifying your hard drive using Disk Utility. 


    OS X: About OS X Recovery
     

    To start your computer from Recovery, restart your Mac and hold down the Command and R keys at startup.

     


    Best Regards.
