Hello, Someone press try to help me or find a good workaround. Since updating to OS X 10.10 Yosemite, my iMac wakes up roughly every two hours. I am aware of the "wake for network access" feature, but its turned off. I took a quick look in Console and I found the following message: Kernel: Wake reason: RTC (Alarm) I believe this is the "wake for network access" kicking in, but the feature is switched off in settings. Please, can some expert try to help me switch off the feature? Im unable to sleep at night and its also irritating during the day. Please don't comment "switch off your mac" because I am aware I can do this . Thanks in advance for any help!
