Re: That's not very typical, I'd like to make that point.
Seems like par for the course to me. Apple has routinely only offered fixes in new versions, though this has usually been bug fixes and not security exploits. Catalina breaks a lot (if you're not 64-bit you're not coming in) and doesn't offer much for anyone who doesn't use IOS. I normally wait until January but am planning to skip this one entirely.
