"Detected clock skew" messages on Mac desktop

Posted: Fri Mar 10, 2023 6:45 pm
by jonault
Switched to v8 on my Mac Studio yesterday. Things seem to be working fine until after I went to bed - apparently the Mac started trying to go into sleep mode because folding slowed down to a crawl & I started getting clock skew messages as if it was going to sleep & waking up repeatedly.

I can't find any setting to tell the Mac not to go to sleep; I have turned off the setting that puts the display to sleep after a certain amount of inactivity, maybe that will help. Not sure what else to try.

Open System Settings and search for sleep.

I don’t remember where it is on macos 13, and I’m away from my computers for a few hours.

Under Display settings, the Advanced button revealed an option for "Prevent automatic sleeping when the display is off"; I'll try enabling that. Nothing else that turned up when searching for "sleep" seemed relevant.

With macOS 12 or earlier, the setting is in Energy Saver.
Seems odd that Apple hid it.

Note, v8 does not disable sleep as v7 did. There is a request for it:
