I am not sure wheter I have ARD installed or not, but I have not installed it myself so if it does not come with iLife, iWork or Leopard then I dont have it.
I tried to keep my Time Machine off but still have the external HD plugged in, and my computer *DID NOT* start in the middle of the night!
So for me, this bug was because of Time Machine I strongly believe, I am sorry that I do not have any times for when the computer starts but it is turned on when I wake up.
I'll give that a go… fingers crossed.
I've been unplugging my iMac each night, which is a pain to remember to do, and when I plug it in each morning it automatically starts up. That suggests to me that if I hadn't unplugged it it would still be starting itself up each night. Let's hope the PRAM reset works.
Resetting PRAM has worked for me, and now that everyone mentions it I have used to auto-start functions once or twice, and set it to the night. I set it to shut-down around 2-3 AM.
So I think that MY problem has got something to do with the auto-shut-down function gets into a conflict with Time Machine or something. I'm just glad that everything is worked out.
I have found a solution that cured my spontaneous reboots during early morning hours.
I removed the EyeTV software and reinstalled it from disc along with the two up grades.
Apparently when I upgraded to Leopard the HD directory structure got screwed up. The ..../Library/Application Support folder now looks like this:
The Application folder is as follows:
If you don't have EyeTV installed you will have to look else where for the cause. I would remove and reinstall any software that could possible cause the problem. If all other possible causes are ruled out I suppose it would be safe to conclude that the problem is with Leopard.
I have the same problem and it is driving me nuts. If I forget to turn the volume down before I go to bed the Powerbook G4 starts up and Eyetv launches and I amwoken up to voices in the middle of the night. Even if I shut it down it will start up again a few hours later.
It is not a Leopard problem as my Powerbook is running Tiger!
I hae spoken to several techs at Applestores and no-one has heard of the problem. They suggested PMU reset which I have done to no avail.
Same problem here:
MacBook CD (1. Gen) OS 10.5.1 wakes up at 1am
- no external Hardware attached in any way besides power adaptor
- no ARD
- no TV software
- Leopard only (no Windows)
- Time Machine not activated
Temporary fix: I set the wakeup time to Monday at 6pm then it won't start at night, well only Mondays at 6pm.
Where is the wakeup time stored?
Apple, please look into this.
Symptom: Mac wakes up every night at 1am
History: once upon a time...a wakeup/fall asleep preference has been set and since removed
Consequence: a valid Library/Preferences/SystemConfiguration/com.apple.AutoWake.plist file was created. Upon removing the wakup time from the preferences it was changed.
The file then had the Tag for a wakeup time that did not contain a time. The system upun shutdown interpreted this as 1am/everyday and wrote that information into PRAM.
1. deleted com.apple.AutoWake.plist - this left the information in PRAM
2. PRAM-Reset on next startup (cmd-opt-P-R)
Needed fix by Apple: Change the program that misinterprets an existing com.apple.AutoWake.plist with no time
