Hello Zhero, thanks for joining the Intel Community.
At this moment there are no video drivers released for Windows 10 preview. The only drivers available are the inbox drivers.
The graphics drivers version 4156 are valid for Windows 7 (64-bit)*, Windows 8, 64-bit*, Windows 8.1, 64-bit* only.
If you were able to install the previous version, even though you are using W10, I would suggest you to keep using version 4080 in the mean time.
Please check the following article: Graphics Drivers — Supported Operating Systems
It is important to mention that Apple has requested us, that all questions regarding Apple systems and software be addressed directly with Apple support. I recommend checking the link below for troubleshooting assistance on your Apple computer:
