MP 1,1-5,1 Mac Pro 5,1 wakes from sleep every minute

[rm5]

Hello,

Just wondering why this is happening to my 5,1. I have the machine booted into Big Sur via OpenCore Legacy Patcher, and when I put it to sleep via Apple Menu > Sleep, it goes to sleep, then wakes up every minute, then goes back to sleep again. Anyone know why this is happening?

What does activity monitor show?

This—everything below it was "no," too.

Oh! I also have the following settings for "Energy Saver"

Remove all USB stuff you can for a test ride.

I had the same problem with a Mac Pro 5,1. I could never figure it out. So I would always shut it down when not in use. I discovered the cause of the problem when setting up a Mac Pro 2013. It was a defective mouse, which caused much more serious problems with that computer -- it would overheat while in sleep mode. I never realized that a defective mouse (which still seemed to work properly) could cause such a serious issue. It would be worthwhile to check the mouse.
