Exact steps for others to reproduce the error
just use the .blend file attached with the settings as saved using all populated layers and render with GPU.error test blender 2.77.blend

below messages were output in a console window.
Is the cause not this?
Added subscriber: @Blendify
I don't think that would cause this error. This is I believe because of a tdr time out. However, I do not know how to fix this on OSX
Probably they may not inspect it with the attached blend file.
Data are missing.
And a file is too big.
I think that you should show a concise sample file to inspect a problem.

This is an intrinsic limitation of CUDA which puts a timelimit on the kernels when using display device for compute. Workaround could be to use smaller tiles, but with increased scene complexity the issue will happen again, Real fix would be to use dedicated card for compute.
Thanks for the report, but it's how CUDA works and nothing we can solve from Blender side.

I just got this same timeout error in OSX using a dedicated Titan X GPU (no monitors or devices connected to the card). Im using 2.77a and OSX 10.10.4
