Please help. Anyone else get this? I did have to update this again after the update bombed in the middle of the download, and I had to manually download the .dmg file from the dev portal. After wiping the machine clean of anything related to Xcode, I reinstalled from the App Store. Giving me this every time, even after a restart.

Take out the ColorSenseRainbow plugin from:

~/Library/Application Support/Developer/Shared/Xcode/Plugin-ins

I'm looking into why it's causing Xcode to crash.

When it's fixed I'll post a note up at the GitHub site at https://github.com/NorthernRealities/ColorSenseRainbow
