Seeing how Technic Launcher no longer has an app, I made one in AppleScript to launch it. If you rename the app it will cut your face off and stop working, so don't rename it.
Anyways, here is the download link: -snip-
You can put the app anywhere, it doesn't matter, but if you rename the app it won't work. Make an alias and rename that if you want.
Note: It will create a terminal window to execute the app. You can close this.
