I'm a recent convert back to the Mac just this past February. Before that I had slipped away after System 7.

Anyway, when I got my G4 iBook 8 months ago w/ Panther, the prevailing logic was that Panther ran a bunch of housecleaning tasks as cron jobs. But they were scheduled at night.

So if you turned your machine off at night, or used a laptop that would likely be off, you had a few choices. Let the tasks rarely get run, run them manually as desired (or use a utility like Cocktail), or change the defaulty run times scheduled.

In a thread in the Applications forum someone mentioned that this limitation/problem is no longer true in Tiger. Can anyone point me to more info on this? Or explain it further? I'm curious to know how this works under Tiger.


What do you make of this?:

Thanks in advance!

Same as Panther. Run at night unless the machine is off or sleeping. Then they run first thing when you wake it up.

That's not what happened in Panther. If your machine was off or asleep, the tasks wouldn't run at all.

They run when the machine was woken up. Read more carefully please.

I'm possitive that Panther did not run the jobs when it woke up!

The link you posted above to thexlab in which it mentioned a bug in Tiger that prevents maintenance scripts from being run, is a bit out of date perhaps. When the 10.4.2 update came out, it was announced that this "bug" had been fixed. I was watching this on my daughter's new iMac G5, which came with 10.4.0, and indeed with that OS the scripts did not run. Her computer sleeps at night and hence the scripts did not run in the early morning hours, nor did they run when her machine woke up. After updating to 10.4.2, when I have checked the /log directory, I see the daily.out files updated on a daily basis now, and weekly.out also gets updated, but the monthly.out seems to be a bit erratic in whether it gets updated in a given month. It's hard to really tell since it hasn't been lots of months since 10.4.2 came out, and after the computer wakes up, I can't figure out when it actually runs these scripts if they should have been run overnight and weren't. I can't see a clear pattern, but it seems to check now and then and simply run them in the background if they are overdue. Once in a while, I simply get on her computer (easier said than done with all the AIM and other internet stuff she does endlessly) and run Cocktail, which runs them all immediately. Even harder is to get the 15-min I need to run CCC to back up her disk now and then.
