Time Machine is showing a couple of hundred GBs more than it should.
suggests that TM may not be the way to go.
Update on Time Machine. It's on a 1TB drive and indicates only 73 GBs left, so it has clearly added 100's of GBs. Prior to the upgrade, my drive had less than 400 GBs on it.
By way of clarification...this is not my newer machine. This is still the old one, so a complete wipe becomes a dicey proposition. I had upgraded to Big Sur only to see if the new Quicken would work for me.
Just a thought. This machine is capable of going to Ventura. Would a Ventura install, using the System Preferences link, clean things up?
