If you run cov-configure on Mac OSX 10.6 you will get an error be: Platform info:Sysname = DarwinRelease = 10.4.0Machine = i386 [ERROR] This platform is not supported by Coverity. There is potential for confusion as the release number 10.4.0 refers to Darwin (the kernel version) and not to Mac OSX (the OS version). The supported Mac OS 10.5 uses Darwin 9.x and Mac OSX 10.2 actually used Darwin version 6! Darwin 10.2, 10.3, 10.4 are all versions of Snow Leopard which Coverity SA does not yet support.
Exporting the variable COVERITY_UNSUPPORTED with a value of 1, and cov-configure helped to trick the executable to be supported on the latest OS.
