You can use semas on OSX, you'll need to use sem_open API instead of sem_init. Using here: sem_open, sem_post/sem_wait, sem_unlink/sem_close with success (In Faust Work Stealing Scheduler code). And semas are actually a slight wrapper over Mach semas. You can check that in XNU source (here for instance http://opensource.apple.com/release/mac-os-x-1068/)
