I updated from Yosemite to El Capitan GM, the day it was released and everything was fine until today, when I turned ON my iMac (iMac 11.1 - 27" late 2009).
It just stops loading when the grey screen with apple logo and thin loading bar appears. The bar is blank - no progress.
When I boot from recovery partition and check the disk, it says everything is fine. But it's not. Tried reset PRam ... Etc.
Please see attached photo of my screen. Any idea if it can be fixed? Thanks so much
