Q: El Capitan Cannot start after upgrade
Dear all,
After my mac downloaded El Capitan and restarted itself, the loading page appeared and the loading line below the apple sign started to install, BUT stopped at about 90%, for hours! I left it go to bed. I woke and found same page still loading at 90%! So I force restarted the computer, a log in page appeared, once I type my log in details the loading line started load but stops at half way Now! Anyone knows what to do Please? I need at least to go back to previous OS X system so I won't lose my files.
look foward to hearing from your suggestions! many thanks!
MacBook Pro (Retina, 15-inch, Late 2013), OS X Yosemite (10.10.5)

Hi JustJanet,
I have tried safe mode and reboot, everything worked well in safe mode and the system shows OS X El Capitan as well. So It means the operation system is installed. But somehow it doesn't start up.
So I called Apple Support. That's what she advised me to do which solved the issue:
1) Log in safe mode -> System Preference -> Users & Groups -> unlock to make changes
2) Select the Admin user -> click "Login items" next to the password
3) Delete all the items in there
4) Open Finder -> on the top menu -> select Go while press ALT at the same time -> a new folder "Library" appears
5) Click Library -> delete all of the files in these folders: Caches; LaunchAgents; Saved Application State.
6) Click Go on the top menu again -> Go To Folder -> type: /Library/Caches -> click Go below ->delete all of the files inside
7) Repeat the above -> type: /Library/LaunchAgents, then delete things inside
8) Repeat the above -> type: /Library/StartUpItems, then delete things inside if there is any
9) Repeat the above ->type: /Library/LaunchDaemons, then delete things inside
10) Restart computer to normal mode
11) It should solved, the computer should now log into the El Capitan perfectly. Then you can empty the Trash.
Try it, and let me know if it solves your son's Macbook!
Best,
Michael
