Hey all this is my first time posting.

I have Tremulous installed on my PowerBook G4 (a Mac laptop). I downloaded Trem from the apple website just fine, and I can play and all that great stuff. I just have a problem with downloading maps and other items.
When I download a map (as a .pk3 file, i think), my Mac gives me the message that "the BASE folder cannot be modified.... you do not hae sufficient priviliges...." and blah blah blah. So basically I can't download maps. Is this my computer, or is it because I'm running Trem on a Mac?

Another problem that I have is creating a server. I go into the game, click on "create server," get all of my stuff set up and then I start it up.... and it crashes. Every time. I figured out another way that doesn't crash, typing /devmap atcs or whatever in the console, and I can play online with others, but then I have to reset all of the BPs and stuff every game.
What is happening with the maps and downloads? I would appreciate any help you guys could give my on this.
Thanks.
