OSX Installer broken, can't boot from latest image

[partap]

I just got my rpi 2, and I'm trying to install xbian on it.

Unfortunately, the installer fails to run now... I'm getting a weird /bin/sh error, although the installer doesn't appear to be a shell script: Screenshot


I'm running OSX Yosemite 10.10.3.

Then I figured I could just try directly loading the latest img file form the website, but that's not working either.

Maybe I'm just doing it wrong... I used dd to write the img file directly to my SD card, but it doesn't boot. Also, I noticed that it only partitioned about 1 GB of my 16 GB SD card, which makes sense, since that's the size of the img file... obviously I need a different method for writing the img to an SD card...I guess that's what the installer is good for...or would be, if it worked...
