Short description of error
When using 'GPU Compute' (in Cycles Render), the 'Render' and 'Preview' worked correctly, but when I bake the combined texture, the progress bar always stay 0% and the whole compute gets totally frozen. (Then I can only force restart it)
I also have tried baking some other kinds of texture:
Diffuse: same problem
Shadow: same problem
AO: No problem, worked correctly.
Exact steps for others to reproduce the error
Just create a simple test scene in Blender (with Cycles Render):

Does this still happen with latest builds from https://builder.blender.org/download/ ?
If so, are there any messages printed to the console? It also worth running Blender with
--debug-cycles
command line argument to make prints much more verbose to see where exactly things stuck.Hi Sergey,
I have tested the latest build you mentioned (Hash:
d852715
), but the problem is still there.Here are the console messages:

Please notice that since the computer got totally frozen when this problem happened, I can't directly copy and paste the console messages at that moment.
The above [Part 1/2] are what restored in the Terminal after the computer restart.
The Part 2/2 is the moment about 20 minutes after I clicking the 'Bake' button. You can see the time on the photo shows 3:44pm, but the real time I took this photo was about 4:09pm. (Because the compute got frozen after i clicking the 'Bake' )
Ok, so it still happens. Will try to reproduce here on mac in the studio. At the meantime, worth sharing .blend which you used. Even if it's trivial, so to be 100% sure we're configuring everything in same exact way.
Sure. See my .blend file here:

There is no solution yet? Am i the only one waiting?

I have the same Mac model and the same freeze, apparently baking causes the GPU to hang. In my case, after ~30 seconds OSX detects the freeze and then proceeds to restart the GPU and kill Blender.
Not sure if it helps, but here's the GPU crash file generated by OSX:
Kernel_2016-11-12-171733_MacBook-Pro-de-Nacho.gpuRestart
And the application crash:
blender_2016-11-12-171734_MacBook-Pro-de-Nacho.crash

please try a build from builder.blender.org/download
