What the?
Apple or the developer should not install apps that aren’t compatible with the currently running OS. I happened to update this last night along with other updates and now it doesn’t work because I haven’t upgraded to El Capitan.
Unlike some Apple apps, it doesn’t even give the option to download the older version that’s compatible with Yosemite.
Fortunately, I have a time machine backup, but it’s still leaves a bad feeling that an update only supports El Capitan and would download without warning.
The app was good before. We’ll see how things are once I rebuild my system with El Cap.
