Ive been having the same problem also but when i run the TechnicRun.command it says this:
/Users/nosirrbro/Desktop/Technic/TechnicRun.command: line 1: {rtf1ansiansicpg1252cocoartf1187cocoasubrtf390: command not found
/Users/nosirrbro/Desktop/Technic/TechnicRun.command: line 2: syntax error near unexpected token `}'
/Users/nosirrbro/Desktop/Technic/TechnicRun.command: line 2: `{fonttblf0fnilfcharset0 Consolas;}'
logout
[Process completed]
As the title says, java 7 won't let me launch technic and I'm on mac,i even uninstalled java 7, and my friend has never had java at all and it works for me. im guessing what the problem is the fact i had it and there are trace files of it.
Please help!
