When I play mac I get this error

That's not a Mac-specific thing. It's simply because the version you have is meant to be played on B26. I'll upload my B27-compatible version, functional loadouts and all. Let me just go set that up.

EDIT: Here it is. I know there was another B27 version earlier, but it sounded like it was a bit patchy, where as this one isn't. Well, not terribly, anyway.

You used Weegee's version right? Not the really old version in the 2nd post. If yes, then it's something you're doing wrong because it works perfectly for me.

Thanks, it works perfect. Also are there only 3 actors or is that my problem

There are actually only supposed to be two actors; I just felt like making a Crobo-brainbot. Which is to say, it's a Light classified as a brain.

looks amazeing downloading

EDIT: Played it amazeing can you make maybe a special ops model that has no explosin on death and maybe a lazer sniper

I used the version Nocifer uploaded, and when I use them on the meta game, the game crashes... Oh, it is probably the other faction, that I did not tested yet, Wehrmatch.

Im going to list a few bugs here for some reason when there in your bunker they sit down and dont move but can still shoot and when you select them for use they stand up and outside they stand up fine know why?

They probably detect the ceiling as being too close, so they duck, they are kind of tall.

Noticed another bug the robots range is small and they dont shoot when being shot at when for exampel a coalation guy will shoot back this severly limits the use of the robots greatly

For one thing, the mod's creator is no longer active; this is a version of the mod from a long damn time ago. So, no, no new content, especially if you can't ask for it with correct spelling, punctuation, and grammar.

As for them just kinda chilling in bunkers, if I recall correctly, it's a matter of the fact that the script that specializes them to match their guns also overrides any AI setting that they have, so instead of the default patrol mode, they just kinda chill there. MidnightMuffin may also be right about the ceiling, though I don't actually know how that works in CC.
Long story short, you have to manually set them up to do what you want.

Since each replaced model is different based on its assigned weapon, how hard would it be to make the sniper-types spawn in sentry mode, assault-types in brain hunt mode, etc?

Probably not very, but you would have to manually edit all of the relevant scripts, which, of course, requires a functional knowledge of lua. So, feel free, but I know it's a bit beyond me.

do tell me that this is applicable to 1.05.

It should be compatible with 1.05, but you should go first test it, then ask.
