Engine Error : Could Not Load Library Client

Whenever I launch Garry’s Mod, it has a black screen for a second, then it goes to a blue screen that says “Loading…” in the bottom right corner. Then it says “Engine error : Could not load library client” And crashes. Anyone have solutions ? ? ! ! I have a mac 10.5.8.

You don’t need to keep making threads. Someone will help you eventually. All I can say to help is update your OS.

Sorry but it just pisses me off I’ve had this problem for a year and Garry’s Mod support doesn’t reply.
