Mac starting up again after SD shuts it down

[ben428]

Hello,

I have my nightly SD backup set to shut the computer down when it's done. Occasionally it has seemed like it didn't shut down, because there was evidence that the computer was on all night, but the log never had any errors and ended with "shutting computer down."

Then last night I was in the room when it shut down and saw that it _did_ shut down properly -- but then it immediately started up again. Any idea why this would be?

I'm running OS X 10.6.6 and SD 2.6.2 (v.87). I don't have this problem if I shut down the Mac manually or using the scheduler, as far as I can tell.

Thanks

Ben

I don't know whether you set SD! to restart your Mac, but perhaps you have a "Wake" Event set in the energy saver preference pane?

I do have it set to wake at 6:30 a.m. in the Energy Saver preference pane. Could that be causing this, even though it happens at 9:30 p.m.?

[dnanian]

No, it shouldn't. But we also can't 'wake' the Mac. When we ask it to shut down, that's all we do, and I can't see how a shut down could be followed by a restart unless, perhaps, something crashed in the system during shutdown... but even then, it's not something I've seen.

Ok, thanks. Maybe it is an OS X problem that is intermittent and it just happened to occur with the SD shutdown.

p.s. Looks like other people have problems with restart happening instead of shut down. http://discussions.apple.com/thread.jspa?threadID=2291072&start=0&tstart=0

Peculiar, Ben. It's not something I've ever seen before, but it always seems that no matter what the problem, someone else on the 'net is having it too. Hopefully their solutions can help.
