Upgraded to Catalina several hours ago. iMac has gone to "sleep" 4 times and each time failed to "wake". Had to do "hard reboot". Anyone else?
Same here. After update to Catalina my Mac will not wake from sleep following inactivity or forced sleep. Ran first aid with no problems detected, and energy saver settings are set to default. Not good.
MB Pro Retina Early 2013.
Thank you for the help. Resetting the NVRAM/PRAM fixed my issue. iMac (21.5-inch, Late 2013)
Have you installed any third party drivers?
as of today this is still working. this is the fix!
Thank you very much. That appears to have fixed it!
This worked!!! Thanks
(Should point out that it's a completely free tool that's been around for ages, so not trying to plug some paid or freemium product here)
Yes i noticed it is happening to me also, going to try the (answered fix by den.thed)

Nothin has worked for me. this is ridiculous!
I tried and didn't work. My Mac with Catalina doesn't wake up every time it goes for sleep after closing the lid.
To be honest this is the most bugged MacOS Apple has released in a long time.
I tried this as well, and still have the same issue.
It's happened again, so can no longer recommend the OnyX tool to solve this issue.
Go to folder /library/extensions and if there is a file in that folder "Trigger5Core.kext", move it to the trash and empty the trash.
This did the trick for me!
I get back the laptop from Apple with resetted EFI and 10.14.6, now (of course) all working properly. The problem is solved.
I am having this same issue. Called support spent 2 hours on the phone and still continues to do the same! It's very annoying and I need it fixed NOW!!! Or can I just revert back to Mojave?
