Can't Get Doom Legacy or TC's To Work Help!

How do I get Doom Legacy or any other TC such as the Twilight Warrior to work on my Mac?

Last time I checked, Doom Legacy isn't a TC. Unless, of course, there happens to be a TC named "Doom Legacy", that I've never heard of before.

Did you get the MAC version of Legacy from the download page? I'm not sure how long it's been since the mac version was updated. You may be out of luck.

I did download a Mac version but it is asking for DOOM.WAD, DOOM2.WAD
,TNT.WAD, PLUTONIA.WAD and the only file I have is the DOOM2.WAD, even so when I click on the Doom Legacy Icon it still says I need these folders?

You should ask this on the legacy forums at newdoom. There should be someone around there who can help.
