The new macOS is here; Catalina.
I didn’t know this, but “Catalina is the end of the road for all 32-bit applications and frameworks on the Mac.”
Take the advice of 512 Pixels:
Stop reading this and go download Go64, a free app that will show you how many 32-bit apps are on your system. If you’re like me, you’ll be surprised how many may be hanging out in your Applications folder.
I downloaded Go64 and I’m safe, but you should check it our for yourself. I’m going to wait until the weekend to upgrade, just in case anything breaks. Can’t have my work-flow messed up on a TUESDAY.
