Osx yosemite macbook retina 1st gen, hd4000 opencl crash

[Drakhain]

Hello,

I own a 1st gen retina mb pro with 16gb ram and an 3615qm HT Quad core I7
Each time i want to use my hd4000 in the opencl tab it crashes. I tried everything i though, like:
 - disabling all cpu cores and gt650m cores leaving the hd4000 alone
 -disabling automatic graphics switching in osx preferences
 -both gpu alone
 -HD4000 with different CPU core settings.

I would like to know if someone as the same problem and has found a solution or if it is normal and why.

I'll send the log when i'll get to my mac if you need it.

Thank you very much, have a nice day.

Hello Drakhain,

We suggest to uncheck HD4000 in OpenCL tab and do not use it for processing, as integrated graphic cards do not usually result in any considerable processing boost.
