OSX sleep mode is quite annoying. I have 2 switches on my computer desk, one is for iMac, the other is for another peripheral such as printer, scanner, external HDDs and background lamp. But everytime I put my mac (on osx) .. The sleep mode is too sensitive. Any unplug/change could wake up my mac. I switch off second switch, my mac woken, maybe because all device switched off by doing so. Not to flamin here, but windows 7 sleep mode dont do this. Only when i press keyboard/mouse that it would be woken up. Any settings i can do to change this?
