it semi-works on mac:

 #ifdef Q_OS_UNIX

is indeed true. But /etc/os-release does not exist and thus the fstat on it fails and only the osName is correctly set as “Darwin” while the osType is incorrectly set as “Linux” and the version and otherDetails are the empty string.

Apparently the way to get the OS X version is to run sw_vers which in my case returns

th-nb-tmpmbp02:subsurface Robert.Helling$ sw_vers 
ProductName:	Mac OS X
ProductVersion:	10.9.2
BuildVersion:	13C64

The three lines can be obtained by themselves with command line switches like -productVersion

Best
Robert
