Every macOS release breaks a few things, but to be honest it's not much of an issue. Here are some recent things that required code changes from developers: - disabling user interaction when trying to request items from the keychain - views no longer clipping to bounds by default - installing login items and background services The latter two were understandable, because they were caused by new features, but some are just caused by a lack of testing. It's not a big deal, and I'm sure Electron apps have similar issues, but app developers do have to put in some work to make sure their apps keep working properly on macOS.
