I typically put the machine to sleep each evening before retiring and, after checking the mail and news of a morning, before lurching off to the workplace. I note that with increasing frequency the computer restarts rather than reawkening, whether I begin by tickling the mouse or tapping a key—it seems to me that this has happened at least four times in the past seven days: I will begin keeping a log.
This would be vexing if the unit did not boot up so briskly (about thirty seconds vs. closer to three minutes for Old Blue, its predecessor), and it certainly serves as incentive not to leave works in progress unsaved overnight. At that, I appear thus far to have been lucky, given disturbing reports of brother iMacs lapsing into persistent vegetative states during sleep, reviving only after (figuratively) violent shaking or not at all. Clearly the phenomenon bears continued scrutiny and further research.
cordially,
