Before upgrading to OS X Catalina, find out which apps will be disabled [View all]

If you're using OS X Mojave or an earlier version, have you been seeing alerts like this one?


Some application developers have created or are working on 64-bit versions of their apps, while others have no plans to go beyond the current 32-bit version -- or plan to charge customers to upgrade to a 64-bit version.

St. Clair Software's free app Go64 will check your system for 32-bit apps, none of which will work with OS X Catalina.

I just ran Go64 on my machine and found that I have 220(!) 32-bit apps installed! Now, many of these are already obsolete or never used, but some are apps I count on daily or weekly, like Adobe Photoshop Elements 16, Adobe Photoshop Lightroom 5, Adobe Acrobat Professional 8.1, and various Canon apps for my old inkjet printer, for example. Others are apps I don't use often, but really like to have, such as some video editing and conversion apps, utilities and productivity tools, etc.

I really really don't want to go to a subscription model (rent-to-never-own) for the Photoshop apps, for example, but I suppose I'll eventually have to. In the meantime, I think I'll stick with Mojave until I've had time to do more research.
