iMac constantly wakes up from sleep after Catalina update
Mac wakes up continuously when sleeping. However, the night after a SMC reset, it sleeps without waking up. Just for one day. The following days it resumes the wakeup-party, maybe once every 10-30 minutes. The screen does not light up, and it goes back to sleep by itself.
I have no conscious setting that would trigger this.
- Everything in energy saver is checked off (besides put hard disks to sleep when possible)
- No sleep/wake schedule
- Bluetooth is not allowed to wake this computer
- Notification center > Do not disturb when display is sleeping is checked
- I turned wi-fi off, didn't help
- SMC reset works just for one night (lol?)

This always starts with <private> then it enlists RTC (real time clock?). I understand SMC is supposed to fix this RTC issue (didn't) but can someone enlighten me on what a <private> reason could be?
I never had a problem with Sierra. (my previous ancient OS)
USBs are a backup drive and a wacom tablet connected via USB and thunderbolt.
I did disable the backup but the wacom is turned off and cannot start without its power button.
I hate to load my big files everyday after having to shut it down so it wouldn't wake me up.
Any help is much appreciated. :(
