My 27-inch iMac (late 2013) running in High Sierra has been stuck since this evening.
After booting up, I tried logging in as usual, but it does not let me in. Right after entering the correct password and hitting enter, all I could see is a spinning beach ball along with a white wheel. I waited for hours… but to no avail.
After going through several forums, I tried to start the system in safe mode, but the problem is still the same. Using Cmd + R, I also tried repairing the disk using Disk Utility’s First Aid option but the problem still persists. I have thought to try reinstalling the OS but have not done.
How can I resolve the problem?
