I just found this too. socket_vmnet/cli.c appears to be using the macro __MAC_OS_X_VERSION_MAX_ALLOWED. Searching the MacOS14.sdk for that macro, I found it defined in “/usr/include/Availability.h” (note the capital A).

I suppose the solution here is to patch it in the Port to inlclude “Availability.h” instead?
