Apple released macOS 10.15 Catalina this week. All current versions of my paid apps are compatible with it, as far as I can tell.1 Please let me know if you run in to any difficulties.

If you use the Alfred, Fantastical, TaskPaper, Messages, Notes or ReadingList extensions, you’ll need to download updated versions of those extensions (by clicking the links in this sentence).2

Personally, I’m holding off on the upgrade on my main machine. I think it could do with a couple of point releases to iron things out.3

  1. My free app, Scroll Reverser, has some difficuties and is in need of an update. 

  2. Updated 16 Oct 2019 to add more extensions to the list. 

  3. By contrast, I found Mojave very stable through the beta period and upgraded immediately on release.
