No offense, but why should the software developers just pour money and resources into maintaining ever changing OS requirements and hop through Apple loops for no visible customer benefit (e.g., better and additional capabilities)? Why do software developers have to spend money because Apple keeps changing the stuff constantly? UX retina are non-trivial changes. In the case of Qt, I recall that this meant changing the version this dropping other OS versions that were previously supported unless you duplicate all development effort. Apple has NO incentive to not keep changing everything and breaking stuff thus forcing people to constantly upgrade and buy new hardware. For me, there weren’t any material changes in the OS I was happy and started using.
