The iMac will not shutdown as normal, the spinning loader is visible and it stays in that state if I don't interrupt it using the power button.
I want to be able to shutdown as normal, at present I'm having to use the power button on the back to interrupt.
I've noticed a few posts on here with the same problem, unfortunately i dont have enough 'reputation points' to comment on their thread. My workflow has stalled to a halt since upgrading to OS X 10.11, El Capitan. Adobe InDesign is terrible and I am really disheartened with Apple for the first time since 1988.
I checked the filesystem with Disk Utility
