Just in case any Apple Metal engineer is wondering if anyone is super excited about getting the Metal system trace tool in Instruments working for OS X Metal work, the answer is a emphatic yes! It's really all I want with the next Xcode 7 update.
I am also looking forward to an Instruments Metal System Trace tool for OS X. It's really the one missing piece devs need for porting/creating high performance apps on OS X. Hopefully we will see an unveiling of a new tool at WWDC '16.
I have Xcode Beta 8 and I can't use it (Metal System Trace). It says "This device is lacking the Metal capability" in fine print on the right side of the Instruments screen. Do I have to install OS X Sierra Beta, too? And yeah, that would be pretty cool tool to use.
