well it did and vie been using tekkit/technic for a month or two now and have all the things installed into it. what i did was I checked out this server to play it but it didn't end up being a running server and it said for me to advance to the manual build and i did. but since it didn't work i decided to backtrack to the development build so i could play on the not as good other tekkie servers i had so it installed all the mods and when i start up minecraft I for ome reason have all the files from my original minecraft and it put in the mods when i checked in /application support/ /minecraft/ it had a mod folder in it with reis minimal so i decided to leave my minecraft alone so i didn't make my minecraft incompatible if i can remove the mods without having to delete my whole minecraft folder and restart at building my first house (in a cave by the way) because it took me days of real time to make it and id be really angry if i have to delete it.
And if you can tell me how i can copy my screen i could show you what happened cause i have a macbook pro.
