Is it a know issue? I've never heard about it before.
It's a Rev 2, 2.0GHz iMac.
The error code in the log is
AppleSMU -- shutdown cause = -122
But I can't find any reference to this anywhere else.
My iMac is about 14 months old, but I had a new power supply about 6 months ago as it was making a high pitched whine.
Anything else I can do, or do I have to get it repaired??
