Does anyone know of a good, helpful, forum to get help and advice about an old iMac that is playing up?
I know there are the official Apple forums, but from years back I found the peeps there are more annoying than helpful!
In case there are any experts here…
Mid 2010 27in iMac running High Sierra.
Internals are mostly as standard, expect I removed the optical and replaced with with a ssd. I did this years ago, and everything worked fine. Until now.
The machine itself hasn’t been used for some time, although it has been switched on and woken up from time to time. I was just getting it ready to give a friend, and that’s where the issues started.
Initially I added the friend was added as a new user and I removed my user account. The issue is that sometimes it won’t wake from sleep, instead going to a black screen with a white line alone the top. if you let it sleep again it normally wakes up fine. Although sometimes, when away, the screen just goes white. Again, letting it sleep and woken seems to fix things. Sometimes you have to reboot.
I figured it was best to just wipe and re-install the OS, so did that but the issue still persists. I thiouth maybe it was the ssd I added causing the issues, so installed the OS on the old HDD, same issue.
At this point you’d nornally be saying “do an SMC reset”. And this is there it get’s interesting. I can’t! The reason I cna’t is that as soon as it’s plugged in, it boots. It doesn’t wait for the power button to be pushed. And this is with the “wake after power failure” option off.
Anyone any ideas, or know of a good forum to try for advice?
