5. Actually, I'm running it now. But Catalina only supports a LTS version of Firefox, not the latest version(s).

Firefox is painfully slow on this machine -- so slow that I prefer to launch Safari just for speed, but Safari has other misfeatures I can barely tolerate.

I think I'm about to retire this iMac and install Open Core on an i3 iMac to patch-install a later version of OSX. This one (Core2 Duo) will be diverted to background jobs all day.

What I really need to do is get my Linux boxes up and running again (long story). I've largely abandoned Apple for many purposes in favor of LInux, but I still like to do my email, Web browsing, and most file handling in OSX. Programming and math/science got to Linux.

Thanks for suggestions though.
