Hello,
I’ve got a A1311 iMac with few problems!
First, when I power it on it gives me a question mark (I’ve erased the partition), before this it got stuck on around 50% progress bar, and I couldn’t do anything, I tried to repair on another mac using disk utility with no luck, so I decided to erase everything, so I could try to start the boot option which I could not do.
Now, I’ve got a dead mac which doesn’t let me choose the boot options or transfer mode or any mode.
Can it be the mainboard? usb connections are working but the boot menu or the controls are not working.
I tried almost everything, SMC reset, PRAM reset, nothing seems to work, tried usb keyboard, old one new one, tried pc keyboard, nothing seems to work
Please help.
