ACTUALLY help him, then stfu.
infestor1, use the MG client described
hereThe file you need that will replace the Tremulous.dmg that runs tremulous for the mac can be found
hereMore documentation than you will probably care to look at can be found
hereAs I understand it, you will need to download the
Tremulous.dmg and replace the Tremulous.dmg that came with your tremulous install. Don't delete the original though, just in case the downloaded one doesn't work for you.
Keep in mind that not all servers have http downloads set up, so it doesn't always make downloads faster for every server. But for any server that does have it set up, the downloads will be MUCH MUCH faster.
If this client works for you and you learn a little more about it all, then you can consider trying out more experimental clients. But I wouldn't recommend it at first

edit: There's a pretty strong likelihood that if you post to this thread and are not actually helping him, that I will just delete your post outright. You have been warned.
