I cannot find the announcements section. However, I went to the downloads section and downloaded the new Warlocks 099c that was released on February 25, and started up a single player game and it seems to be working and the 099b also is working. Some of the older versions like 099 are not working, just as EroticSideburns mentioned.
Edit: Warlock 099 and all 099b and 099c test versions are NOT Mac compatible.
You MUST play the release version of Warlock to be able to play it on Mac.
When I go to Battle.net and look for Warlocks servers, I see ones that say they are hosting warlocks 099c and when I join it begins a download even tho I already have warlocks 099c downloaded from this website! I am kicked from the game on B.net at 99%, and when I try to open the Warlock 99c test file that was downloaded from B.net I get an error saying it is corrupted.
You cannot open any Warlock map with the editor (that is how it is supposed to be).
Are you sure you put the map in the right folder by the right name "Warlock099c" in the "maps/download" folder ?
RGC client is incompatible with Mac and Bnet seems to be hosting versions that are incompatible with mac, so is there any way I can actually play this with others?
I should be able to make Warlock work on Mac, but I cannot do the same for RGC.
There must be some kind of emulator, which can run the RGC client (I'm not the guy to help you with that though).
You could also use garena, but our main player base is on RGC.
