Hello everyone,
Yesterday I went to an acquaintance of mine as he asked for my help after this iMac wouldn't boot up. He already had tried several solutions, such as booting in Safe Mode, performing a recovery installation. I tried the same myself, and did some other things as well. For example, resetting the NVRAM of the system etc.
Now, the thing is, the iMac shows that it is booting. But at around half of the loading bar, it starts to get extremely slow. And when it finally reaches the end, it won't get past to the login screen.
He told me he did do an upgrade after the problem occurred first, so that doesn't seem to be the reason for all this.
I'm not sure what exact model iMac he has, but it's definitely quite an 'old' one: it's one of those non-Retina thicker versions, probably five years old or something. It worked fine for a long time (I can know, because I've seen it work just a couple of weeks ago).
Does anyone have an idea of what might be the issue and more importantly: a solution that might help? I'm no expert in Mac troubleshooting, so I really only used Google to find some possible solutions. But that's all I got. I would honestly not be surprised if it turned out to be any hardware failure, but that's also one issue here: we couldn't get to Hardware Test/Diagnostics. We did hear the harddisk making kind of strange sounds upon the boot process, but that's it.
In summary: iMac of possibly around 5 years old not booting, tried basically every 'basic' troubleshooting method. Could be hardware failure, however unable to test that.
