IMac Pro Sleep Mode: A Better Substitute?


Several people have reported problems when attempting to re-awake their IMac Pro
from sleep mode, eg:

I’ve had these problems too with overnight sleeps, requiring power-off and reboots. On two occasions the machine (a midrange IMP with 10 core, 16gig graphics, 64 gig memory) was hot when checked in the morning, and the fan came on LOUD on reboot, as reported in the link above.

Here’s my better substitute for sleep mode. First go into sleep mode, then immediately tap the mouse and/or spacebar to bring up the password box and muted screen. That’s it! After a few seconds of no password entry, the screen will go blank, and—as far as I can tell—it’s now in a state very like sleep mode (eg, any extra monitors attached go into a minimal power state, and any attached disk drives function normally after re-awakening). Also the machine will reliably wake from this sleep-plus state in just a few seconds, after any normal period of time (checked up to 12 hours).

Any explanations of what is going on here, including whether there are any downsides?
But it’s so convenient for fast, safe startups that all of my sleeps are now sleep-pluses!

Hi,

I'm experiencing the same thing. Have gone through all Apple support options who, although have not found a solution, have been really helpful I must say.

I stumbled on this post yesterday and tried it last night. It worked! At least this is a short term fix. Not sure what is going on here but I've relayed this to Apple support who may be able to see what the trigger is.

I'll keep you posted.

Thanks!

Have you tried just logging out?

I also experienced the fans spinning crazy fast when it was in sleep mode. This just happened one time only. Must have been a glitch.

Two other weird things: Once, the Magic Keyboard would not respond - I had to turn off, then back on for it to reconnect. Also once, the Magic Trackpad was non-responsive after sleep. There was no "click", it was like it was turned off. I just flipped the switch and it reconnected. Both had >35% battery life.

These are a bit concerning, but since each one has only happened once, it's not too frustrating. I am hopefully macOS updates fix these things going forward.
