I read online that I needed to upgrade to Big Sur to transfer data from my Pro to my Air. I slowly began to rebuild access to the websites. I deleted LassPass and installed Dashlane.
In addition about 2 months ago I realized that for some unknown reason (maybe I was hacked separately?) all the passwords in my password manager, LassPass, had changed without my permission. It deleted multiple important data files.
About 4 months ago I used Clean My Mac on the MacBook Pro. Multiple serious problems with the two laptops I use for my medical practice.
