Sudden unexplained shutdowns - unrelated to Sleep
My imac is not one of the ones covered under the repair extension programmes for power and video issues. And I've already tried resetting the PMU.
It's difficult to point to anything specific that might be causing it, but below is the system.log from the most recent incidence. As you can, things suddenly seem to get intensely busy... Any thoughts or speculation as to what is causing this.
