Hi all, My wife’s Mac keeps going to sleep at random intervals its a MacBook5,1 Mac-F42D89C8 This can happen at any time including : Regardless of being plugged into the charger or running on battery If it’s writing a CD it will sometimes enter sleep mode When synchronising with an ipod - it will sometimes enter sleep mode I’ve even gone as far as using a spare hard-drive, formatting it and installing EL Capitan on it - after the install had finally finished - I had hoped that the sleep issue would disappear… Around 10 minutes later - it went into sleep mode again the only way to wake it would be from pressing the power button and waiting for a response.. Thanks Andy
We had same issue here. Somehow the powersettings got screwed up. Al though it showed go to sleep after 45 min it was ignored. I suggest you drag the slider some where else. Restart machine and try. you can always use the terminal to force: https://github.com/kevinSuttle/macOS-Def… Never go into computer sleep mode sudo systemsetup -setcomputersleep Off > /dev/null
