My users are reporting crashes with my macOS audiounit. The crash seems related to colorspaces (log at bottom).
Recently I added the following code to change the windows colorspace in 'viewDidMoveToWindow' like so...
						colorSpace = CGColorSpaceCreateWithName(kCGColorSpaceGenericRGBLinear);
						nsColorSpace = [[NSColorSpace alloc] initWithCGColorSpace:colorSpace];
						[window setColorSpace:nsColorSpace];
My intention with using a linear colorspace is to achieve nice gradients and alpha-blending with gamma-correct results.
I suspect that this colorspace might not be supported on the older versions of macOS? or maybe the problem is with particular graphics hardware? but I'm not sure. I don't mind too much if I have to fallback to a less nice option on older OS's.
Any suggestions on how to fix this appreciated.
