@mjtsai @grynspan Do it the other way around: if isOperatingSystemAtLeastVersion: exists then use it, otherwise use the old thing.

@gparker @grynspan calls to -mjtIsYosemiteOrBetter so it is very clear when I can eventually remove the check.

@mjtsai @gparker @grynspan I can confirm that -isOperatingSystemAtLeastVersion: existed as SPI in Mavericks.

@ameaijou @gparker @grynspan Yes, I just checked 10.9.5 and the method seems to be there (and work).

@mjtsai @ameaijou @gparker Can you please share some sample code that demonstrates this?

@grynspan @ameaijou @gparker python -c "from Foundation import *; print NSProcessInfo.processInfo().isOperatingSystemAtLeastVersion_"

@mjtsai Also better future-proofed, as you don't have to wait for new constants to be defined.

@mjtsai @grynspan I’ve been using the /System/Library/CoreServices/SystemVersion.plist hack since Gestalt deprecated. New API sounds good!
