xcode - Metal frame buffers on OSX -

soo, came problem after updating xcode 7.1 beta 2 ( well, didn't work before ). before had piece of metal shader took apple samples ( metaldeferredlighting ):

struct fragoutput {     float4 albedo [[color(0)]];     float4 normal [[color(1)]];     float  depth [[color(2)]];     float4 light [[color(3)]]; }; 

and when use color output/input doesn't work, after updating xcode 7.1 beta 2 got following error on os x:

fragment shader parameter attribute 'color' supported on ios (requires -std=ios-metal1.[0][1]) 

in xcode 7.0 beta didn't work, got black screen.

is there way make frame buffer ( render targets ) work on osx?
