This is a simple Mac utility that I made today that allows you to set the offline username associated with the minecraft launcher.
This updates the launcher_profiles.json file to run the launcher in offline mode. (Config hack from UXRI)
Screenshots are attached. I couldn't figure out how to post them.
Virus Scan links are also in an attached text document (can't post links for some reason).
How to use:
1. Download the minecraft launcher from minecraft.net
2. Run the offline utility and enter the username you want.
3. Run the minecraft launcher
4. Click offline mode and everything should work!
Again, this hack is Mac only, I could possibly write a windows version if anyone wants me too.
Hope I posted this correctly, not sure what is wrong with my ability to post links (this is my first hack release).
Hopefully this works well!

EDIT: Also if it was unclear before, this is a way to play the latest 1.6.1 update without a cracked launcher.
