At night I shutdown my Macs, switch my surge protector/power strip off (which fully cuts power to computer). When I switch it back on in the morning my Macs auto-boot without me pressing the power button. This seems to only happen if the power has been off overnight. If I simply cut power and in an hour turn back on, it probably won't auto-boot. This is extremely annoying and I can't figure out how to fix it. I'm using latest firmwares and I don't think 10.8.5 is going to fix it. This happens with with Mountain Lion on MBA mid-2012 & iMac 2007. Any ideas?
