I am hoping the community might be able to help.
I have a late 2014 (?) iMac. Recently I have noticed some odd bits and bobs happening. The camera would fail in the middle of video call, programs would take a long time to open. This afternoon the whole system froze. I could move the mouse, but nothing else. It would restart/sleep etc, even after leaving it for more than 30 mins. I shut the thing down by pressing the on/off key (possibly a mistake).
When rebooting I get to the login screen, and while I can move the mouse around I can not get the login password box to reveal itself. I have tried zapping the PRAM, and safe booting but it hasn’t helped.
Any thoughts as to how to process would be really helpful.
