I have a common question. There is some app. I know it's compatible with Mac OS X Version 10.7.5 (Build 11G63). May I be sure if it's fully compatible with:

  • 10.7.5 (Build 11G63b)
  • 10.7.4 (Build 11E53)
  • 10.7.0
  • 10.6.8
  • 10.8.1
  • ...

etc. I suppose the answer is always "no", because every build has its special features, it needs special testing. Is it really so?

The answer is always no (one cannot assume compatibility backwards or ahead). Universal truth that applies to everything running on anything.
