"Putting back items currently in trash Yesterday I moved a bunch of files to the trash. Unfortunately, I trashed some files that the OS seems to need, but I don't know which ones. So I want to put back from the Trash all the files I moved to trash yesterday. I can't run a restore from Time Mach because Time Machine restore needs one or more of the files I moved to Trash. Please help."

Reinstall the macOS:
You couldn't have moved system required files without having any ability to do so (which is something to stay away from). As for fixing all of this, you need to reinstall the macOS.
Reinstalling the macOS:
Reinstalling the macOS will place moved items back to where they should be, and will replace damaged system files.
1. First, Back up your Mac:
Create a Time Machine backup of your Mac, so that you can have something to restore your Mac from, should anything go wrong with the reinstall. Use an external Hard Drive of at least 1.5 times the size of your internal hard drive.
2. Then, Reinstall the macOS:
Nothing would be deleted. It's just that items that have become corrupted or deleted, would be replaced or reinstalled back to where they should be. Go Here: How to reinstall macOS from macOS Recovery - Apple Support
