Q: Sign in hangs for Apple ID login after El Capitan install
After installing El Capitan on my iMac, the sign in hangs for Apple ID sign in on iCloud, App Store, and iTunes. Everything basically freezes at the sign in and the only option is to force quit. I cannot use iCloud, App Store and iTunes at this point. I attempted restarting the iMac and signing in again, but the same issue arrises.
iMac, OS X El Capitan (10.11)

I Had the same issues, turned out that in upgrading to el capitan, my imac lost the serial number that was stored on the logic board. You can check whether your machine has lost the serial no or not by going to the "about this mac" under the apple logo. If the serial number is listed as unavailable, then that likely is your problem.
The issue can be fixed on your own- by going to rogersm.net- how to set your mac os serial number to use icloud. I followed the instructions and after 2 hours got my imac back to working order.
However as the site says, no guarantees. If you still have apple care, you may feel more comfortable having a apple service person do the job.
Just to let everyone know what could be the issue , and a solution that worked for me.
