I'm sorry for the delay in responding. I have a day job and I don't get to check and respond to emails as quickly as I would like. Thank you everyone for your generous help!
Cletus answered to your questions:
(1) Macintosh HD has about 1.7 TB of FREE space
(2) I often attach an External HD to the Mac, it has my photo archive on the archive photos are kept in the LR Classic catalog. It's a 1 TB Drive close to full
with about 0.2 TB remaining.
(3) There is no entry for Lightroom in Security & Privacy/Privacy tab. It has entries for PS and LR Classic and all are checked.
