The Apple ecosystem, in general, is notorious for this: If you update your OS, some 3rd party applications will suddenly no longer work, because Apple keeps introducing breaking changes. But, if you don't update your software, other 3rd party applications will quickly abandon you and block you from using their software until you update. So, you're damned if you do, and damned if you don't. Complicating this is: if your hardware is "too old" (as deemed by Apple), you can't update your software, so eventually you're left in the dust. You can't win.
