just yesterday i tried to downgrade my minecraft to what this server runs on and i ended up messing up my minecraft and spending 7 hours trying to fix it. i have now come to terms with the fact that i will probably have to wipe my macs harddrive. i have two problems. 1 i need to wipe my computer with out losing my operating system and all the important files my computer needs to run with(i no longer have my os x cd).2 i cant wipe windows 7 which i am running through boot camp. any help on how to do that would be much appreciated.
