Hey, So my 2007 iMac running 10.7.3 with 4 GB of RAM will not stay asleep any longer. I have it set to sleep automatically every night at 11pm and it hasn't been lately, but it will wake up sometime later between then and 7am. The only apps I have running in the background are DropBox, Arq, and F.lux. I also always leave Chrome and Excel running at all times. One thing I noticed is that there are a lot of messages regarding the 1Password Helper respawning among other things throughout the night. This issue has been going on for months now and I have not installed any applications recently that would cause this behavior. This is the App Store version of 1Password. Also noticed this a few times as well: Code: 3/4/12 12:10:10.000 AM kernel: Wake reason: RTC (Alarm) 3/4/12 12:10:10.000 AM kernel: RTC: maintenance alarm 2012/3/4 05:10:10, sleep 2012/3/4 04:10:20 3/4/12 12:10:10.000 AM kernel: Previous Sleep Cause: 0 Any help would be greatly appreciated.
