I picked up Borderlands 2 for OS X in the recent Steam sale because friends of mine would NOT shut up about the game. So I fired it up only to find out that I needed to use a keyboard (lots of keys) + a mouse (carpal tunnel = no) to play. That sucks. I was hoping that I could use a borrowed Xbox 360 controller to play through, but Aspyr doesn't support that. Grr.
So after some research I found a way to use both a wireless Xbox 360 controller as well as a wired third-party Xbox 360 controller. This worked for Borderlands 2 and other games I've tried so far. The cost for this is $5 for the wired controller and $20 for the wireless. Here are the two setups that worked for me.
Step 1: Wireless Xbox 360 Controller
To connect the wireless 360 Controller to my Macbook Pro I got this wireless gaming receiver for $15 (incl. tax) on Amazon.
The computer still wasn't recognizing it, so I installed Tattiebogle 0.11 which you can download here. Follow the instructions for installing and then open up the "Xbox 360 Controllers" icon in your System Preferences.
Link up your controller to the receiver and you should now be able to see reactions to you messing around with buttons and analogs on the 360 controller.
This is great, but many games will still not recognize your controller. So now you need to map your buttons to keyboard commands. To do that you will need to get Joystick Mapper in the App Store.
Once you're in Joystick Mapper you can assign all of the buttons and analogs to keyboard and mouse controls. This will take some trial and error to find out what works best for you, but it does work.
Step 2: Wired (third-party) 360 Controller
There are many many different 360 controllers out there. Fortunately, there are people out there who can help you out. Once you have Tattiebogle installed you can add support for more controllers.
After installing Tattiebogle like described in the last step for the wireless controller, download this link and run the command script to update Tattiebogle. This comes from Shoryuken forum member EddDeDuck. The forum post I found this is here.
(Note: found out the link for the command script is now broken. File attached to this step)
You will also need the Joystick Mapper app from the App Store to make this work.
OK, that's it. Have fun.
Step 3: FAQ
Why play games on a Mac?
It's what I have. For my work, the Mac works really well. If I was gonna be serious about games, I'd build a desktop machine. Fortunately, the Mac gets a few games thrown its way as well.
Why are you playing on windowed mode?
I'm not. I play on full-screen. It's windowed here to emphasize that it's OS X and not Boot Camp or Parallels.
Why not use keyboard + mouse?
I've had lots of problems with mice in the past with some carpal tunnel issues. They hurt my wrists after using them intensely for 10+ years.
