Old Toad, I hope this shows Full Disc Access.  The Major Issue tab in this program shows that I have to do backups on this system.  I have a network drive that I can use for that.  The Minor Issues tab - and I don't know if this report shows any of this - says that my SSD is showing poor performance.  SSD I think pertains to the hard drive.  Numerous apps crashing; but I don't know which ones.  It is keeping track of unsigned files, which I guess means those that Apple does not recognize.  There is a warning that x86 apps might not always work on this system (What is it anyway, 64-Bit?)
