Hello,
A somewhat unorthodox issue report. I encountered the error messages below
after building the 5.9.0RC QMacStyle against Qt 5.8.0 (hence also reporting via
the ML):

This is when building on OS X 10.9.5 using the 10.9 SDK (which always worked
better than using the 10.10 SDK). I'm not exactly certain when the
graphicsContextWithCGContext:flipped selector was introduced; apparently in
10.10 but apparently in a later 10.10 version than represented by the 10.10 SDK
on OS X 10.9 .
IOW, I needed to protect the new selector with `#if
QT_MACOS_PLATFORM_SDK_EQUAL_OR_ABOVE(__MAC_10_11)` and use the old version
otherwise.
HtH,
René
