Is there any proven_Socket 1150 with M.2x4 support and EFI boot available?

[SERGE2013]

Hello,

Is there any _proven_ Socket 1150 with M.2x4 support and EFI boot available except ASRock Z97 Extreme6?

I have ASRock Z97 Extreme6 with SAMSUNG m.2x4 256GB / YOSEMITE. OSX works, but it only boots from regular SATA HD or USB 2.0.

This motherboard acts so weird when a) booting into BIOS and b) setting up EFI booting so I gave up spending time for what is obviously not working properly and not even consistently. Used BIOS v 1.70 - 2.30 with same results.

Need to keep all my hardware, so looking for the new working motherboard only.

Serge
