> However Microsoft's APIs are not "more stable" than Apple's
You can pretty much always run apps for Windows XP (released 2001) on Windows 10. You can't run any apps from OS X 10.0 (released the same year) on modern macOS. Yes, there was a processor architechture change in there (and a subsequently dropped compatibility layer), but the APIs have changed enough that that isnt the main issue.
