There seems to be quite a few apps that just won't work at all. And I'm not talking about Yosemite support, but Mavericks almost one year in and no upgrades. Developers should just loose their accounts if they do things like this. And Apple seem to be just as bad. They release new Operating Systems every year and want us to buy apps from the App Store and not on the web yet they let dev's get away with apps that just don't work on the current OS. Games like GTA San Andreas (where all the reviews on the Mac App Store after Mavericks came out say that it doesn't run). Is it just me or is this a serious problem with both lazy developers (Rockstar...) and Apple having to make OS updates every year.
