This is my first experience with a mac freezing, truthfully. I'm not sure what the issue is, it may have existed from the start but we never turn the iMac off, only asleep. This only happened when it stopped communicating with the bluetooth keyboard after changing batteries. I did it to clear the PRAM in case that may have been the issue with bluetooth. I only suspect it may involve wifi and/or bluetooth because it makes it all the way to the desktop, then it freezes when it looks for bluetooth devices or a wifi signal. The wifi was used before to connect to a wireless printer.
However I do notice the dock never shows up before it freezes.
I tried booting into single user mode and disabling bluetooth on startup. I wrote a small perl script and interestingly it fails to move bluetooth related .kext and .plist files somewhere else (I got the idea from apple.stackexchange). the script itself doesn't throw any errors.
Furthermore, I can't seem to either turn on networking for ssh or mount a simple usb drive. I'm currently looking for a thunderbolt to firewire adaptor so I can try that.
Is there any particular reason why in single user mode I can move and create files via bash but not with a script? I'll try to set the UID bit see if its a permissions issue.
If push comes to shove and I can't do anything about this, is there a safe way to downgrade to the factory OS without losing data? we went from 10.6 to 10.10. Yeah we missed quite a few intermediary OS's. sue me.
