Hello Juce Community,&nbsp;  
  
I'm on OSX 10.9.5 (Mavericks)&nbsp;and having&nbsp;trouble opening the Projucer, I have the same probelem as here:&nbsp;http://www.juce.com/forum/topic/crash-mavericks-1095

// Projucer is not supported on Mavericks.&nbsp;

I wonder what the best OSX and Xcode is at the moment to work with JUCE?&nbsp;  
Yosemite or El Capitan  
  
Many thanks,&nbsp;

Kris

What works for me:

OS X 10.10 (Using 10.10 SDK in Xcode, with Target Deployment of OS X 10.10).

XCode 6

&nbsp;

I've also compiled the same projects with 10.11 SDK, and on Xcode 7.

Cheers,

Actually, I'd highly recommend Xcode 7 instead of Xcode 6, because that's what we will use to test/fix bugs and add new features.
