Many Tricks:

Moom 4 is only available directly from Many Tricks; it is not available on the Mac App Store. If it were our choice, it would also be in the Mac App Store, but it’s not our choice.

Why isn’t it in the Mac App Store? Because the Mac App Store does not allow apps that aren’t sandboxed. And Moom 4 cannot be sandboxed, as its use of the Accessibility API makes that impossible. So how was Moom 3, which also uses the Accessibility API, on the Mac App Store? Simple: Moom 3 was in the store before Apple required all Mac App Store apps to be sandboxed, so it was allowed to remain in the store, as long as we never added new features.

If Apple ever changes the rules, we will submit Moom 4 for Mac App Store review, but until/unless those rules change, you can only get Moom 4 directly from us.

What a perfect example of the shortcomings of the Mac App Store. MacOS 15 Sequoia adds new window-tiling features that, on the surface, you might think Sherlock Moom — a longstanding Mac utility that automates window resizing/arranging. But Moom does so much more than Sequoia’s tiling features. It’s a fabulous utility from a great developer, but Many Tricks isn’t allowed to offer it through the Mac App Store.
