I wonder if this behavior is normal?!Įnvironment Mac Mac Pro macOS 10.15 Catalina Power Sleep a bug, clearly, but a bug nonetheless. It’s barely audible but you can feel the air flow.

Mine turns on the rear blower after about 90 minutes of sleep. Sharingd and powerd were preventing sleep even though no one was connected? Turned screen/file sharing off and then back on again, and now after about a minute the fans spin down all the way. Use the pmset command-line tool to find out what’s keeping your Mac from sleeping. You can absolutely get a 2019 Mac Pro to sleep and spin down all its fans.

iMac is 1W, even trashcan Mac Pro was 4W. Wow, power usage in “sleep” is 15W, that’s really high. And if you tap the keyboard to wake it feels like only the display is sleeping. But it doesn’t sleep like other Macs where the fan turns off and the machine is on standby. I don’t know if it has its own version of sleep that isn’t deep sleep. But the machine itself will not support deep sleep and the fans will always run. It can do display sleep, and the sleep command in the Apple Menu will trigger display sleep. One weird thing about the Mac Pro I haven’t seen mentioned… It does not support sleep.
