Steps to Reproduce Bug:
Install Forge 9.11.1.965 (On OS X Mavericks if possible) > Install ComputerCraft 1.58 > Try to launch game > Crash.

You may want to try an earlier Forge build. Works fine for me on Mavericks on Build #953.

Your Mac will be unzipping on download. Get a better browser.

I'm having the same problem with the same version of Forge

Did you unzip the mod? If you did, don't do that. You should place the .zip directly into the mods folder.

Mokay. That was as simple as this. I misread the instructions on the website.

Thank you for your help, and sorry.
