So I have a pretty common issue with my 12,2 mid-2011 27" iMac. It shows the folder questionmark icon on startup.
At first I thought that my hard drive was faulty - which it was. So I bought a new one and inserted in the iMac. I then installed a copy of High Sierra on my 500GB external harddrive.
Now my problem is: The hard drive shows up in Disk Utility and is both healthy and able to be formatted. When I Install High Sierra on the hard drive it starts the process of installing and then restarts BUT the questionmark issue still remains. I've then tried replacing the SATA cable from another iMac that I know works but the issue still remains.
The weirdest part is that the hard drive seems to be fine and showing up in Disk Utility as a healthy drive but the computer simply won't recognize the OS.
Is there anyone who knows what my problem may be? Thank you for your help! I really do appreciate it!!
PS: I've already tried resetting PRAM and SMC without any luck.
