I've seen strange problems with my unix command-line application when attempting to build for 10.6 though 10.10. After investigating another utility I noticed a hard break at 10.6.8. My app runs fine on 10.7 through 10.10 when building with Xcode 6 but is only partially functional on 10.6.8. It doesn't break completely, it simply fails to run to completion. The easy solution is to designate the older version for 10.6.8 and earlier and designate the new version for 10.7 through 10.10. There were a few OS calls that changed around 10.9 although I don't remember which ones so my guess is that these changes were the ones that broke operation on 10.6.8.

That way I can know if there's any point in splashing out a whole £14 to upgrade that macbook to Lion...
