Do all gamemodes/addons for GMOD work for GMAC?

Since they are same game do the popular ones work for GMAC or do the devs have to release a mac version of the add on?

If the addon does not use binary modules, then it should work with mac. If the addon uses a binary module, that module will need to be compiled for mac.

so can you name a few popular addons that use binary modules?

That’s all I can think of. Wire and PHX should be fine.
