This also has the advantage of being able to run inside a virtual machine without hardware acceleration. I find it nice to be able to develop and test without needing to run the full games on listen servers. # My primary motivation for this was to make testing easier (for Metamod:Source and SourceMod). I have been able to do so but not without a lot of hacks. This binary is what handles the logic for dedicated servers so I hoped I could do something with them. # I noticed that there are binaries named 'dedicated.dylib' available for each Source engine currently available. # Since Valve has not yet released SrcDS for OS X (and it seems it won't be any time soon), I decided to take things into my own hands.
