Check out a list of 235 apps and versions incompatible with macOS Catalina 10.15
O macOS Catalina It's still in its fifth beta version (or fourth public beta version, if you prefer) and it's officially being released there for September or October, but a lot of people are already kicking their wings to try out all the news of the new system even if it means instability and presence of bugs above normal.
Another aspect besides those inherent in a beta version, however, cannot be ignored: all the apps which are not compatible with the system at the moment. Fortunately, however, this can be easily checked.
Exploring the latest test version of macOS Catalina, developer Steve Moser put his hands into a file detailing 235 applications (or versions of them) that are not compatible with Apple's new operating system. The list in question used by Catalina herself in her installation process to inform the user which of her installed apps are incompatible with the new system.
Most occurrences in the list of very old versions of apps, but some presence are noteworthy: the item related to TextWrangler, for example, states that app development has ended and users must upgrade to BBEdit, by the same developer.
The full list can be viewed or downloaded at this GitHub link, but here are some highlights of apps not compatible with macOS Catalina so far:
iStats Menus 2.9
Box Sync 4.0
Default Folder X 4.3.10
VMware Fusion 3.1.4
Adobe Creative Cloud 188.8.131.522
As you see, these are usually older versions of the apps in question, and anyway, their developers can take advantage of Catalina's next two months of testing to expand support and change the list. Still, is the tip.
