any suggestions?

yeah i'm stupid. i figured that out a second after i posted that last comment. now, because im stupid, how do i use mc patcher. WHat i did was i clicked on the vanilla 1.5.2 jar, clicked patch, duplicated the folder, modded the jar. Still not working. Any other tips?

I tried both, but i'm on a mac.
