Garry's Mod on Mac not mounting CS:S content

So, no matter how many times I’ve rechecked and unchecked the CS:S extensions button, restarted, etc., Garry’s Mod for my Macbook isn’t mounting my CS:S content.

All of the other games are working fine, Ep. 1, 2, TF2, etc.

Anyone have any solutions?

Fixed it, looked at console and had to verify cache of Counter-Strike and Gmod
