Hi Daxill: Thank you very much for joining the Intel® Graphics communities.
In this case, since you are using an Apple product, in order to get the proper technical assistance, please get in contact directly with Apple:
Any further questions, please let me know.
Yes, i am using imac, but in instaled last driver frome this page Downloads for Intel® Iris™ Pro Graphics 6200 . And previously drive from intell work fiine. I think last driver has a bug. Do i have to install old driver?
Daxill: In regard to your question, yes, as an option you can always try to install an older version of the graphics driver, but in this case the best thing to do will be to contact apple for the proper support.
Any questions, please let me know.
Why i must write in apple support about bug in INTEL driver? I think that i should write intel support about bug in intell driver.
