GMod crash when joining DarkRP server

[joseph19645]

Hi, I just installed Garry's Mod on my new iMac, but when I join my favourite server it gets to 'Sending Client Info' and then it crashes.
Here are my specs:
Model Name: iMac
Model Identifier: iMac14,2
Processor Name: Intel Core i5
Processor Speed: 3.4 GHz
Number of Processors: 1
Total Number of Cores: 4
L2 Cache (per Core): 256 KB
L3 Cache: 6 MB
Memory: 8 GB

The error report I get from the crash (it's very long and I think it's got something to do with awesomium):

Common problem, no fix.

[CyanFlare]

It is the Mac. Get rid of it.

[Subject_Alpha]

Awesomium core is unstable on mac. Very common problem.

[Svenskunganka]

Robotboy I'm not sure if you can do this but maybe we should update to the latest OS X version of Awesomium SDK? GMod seems to be using 1.7.2 while the latest stable for OS X is 1.7.4. Same for Windows but 1.7.5 is available there. Might be worth a shot.
