My circa 2012 MacBook Pro is still great, and will still run Catalina. Maybe a more apt description is 'abandoned, and left on the sidewalk to die.') (Well not really, the software and computer still work fine. I could likely hack it to run 64-bit software, but the odds of it running Catalina are probably remote, and most of the software that's on it is 'obsolete' anyway. The days are numbered for my beloved cheese grater desktop Mac, which is now as endangered a species as the snow leopard for which its operating system is named.
