To quote a current much overused phrase we've all heard lately: we're all in this together.....
Apple has a history of adding late changes to a release that are not in the Betas.....I really wish they would stop doing that.
I am testing the CCC beta now. Will let you know how it goes.....
EDIT: Before I posted this, last night, I tried SuperDuper, in hopes it was an issue only with CCC. It wasn't and it isn't. SuperDuper backups produced the same issue....so this issue is more widespread than CCC (I don't have a license for SuperDuper, so I'm going with the beta of CCC as that is my long time licensed backup software).
