+# Help wanted

+My MacBook Pro is 11 years old now and it does not run OSX Mojave or higher. Unfortunately, Apple deprecated `NSUserNotificationCenter` with OSX 10.14 and I suppose they want us to use the newer `UNUserNotificationCenter` API instead. I would kindly appreciate any contributions from folks that own a more modern Mac and are interested in implementing the OSX backend using the new API.
