Ran into a bit of trouble,,,,,I updated my OnyX for each Mac, downloaded the proper ones for each OS.
When I started it on this one, it unexpectedly quit, and acted strange.
So I deleted it.
Then on the other Mac, it hung it up badly, sounded like the poor hard drive was in overdrive, wouldn't let me force quit anything. so I had to hold down the power button. Restarted it OK, its happy now.
So I guess I wont mess with OnyX any more, surprising, as it always used to work just fine.
Wonder what was going on with it.
