Fix for Slow Boot on Thunderbolt 2.0 Motherboards

[tonymacx86]

Problem:
If you have a Thunderbolt 2.0 motherboard, such as the Gigabyte Z87X-UD7-TH, there is a boot time delay of 45 seconds or so when Thunderbolt peripherals are attached.

Solution:
For Chimera/Chameleon, delete /System/Library/Extensions/AppleThunderboltNHI.kext, rebuild cache and reboot.

1. Open Terminal
2. Type the following and enter password:

sudo -s

cp -R /System/Library/Extensions/AppleThunderboltNHI.kext ~/Desktop

rm -R /System/Library/Extensions/AppleThunderboltNHI.kext

touch /System/Library/Extensions

3. Reboot system, and the delay is gone!

Thanks to Genzai in the Thunderbolt 2.0 Testing thread here.

Is their a way to do this without removing thunderbolt support from OSX?

Would this really be a fix if it removed thunderbolt functionality? Thunderbolt support isn't being removed and I suggest you read the linked thread to understand it better.

Yes, is there any chance of this happening?

The board has been fully working since day one of it's release. Not sure what you're waiting for.

As I mentioned, a Golden Build

It is an inconsequential distinction. but if it makes you feel warm inside, keep waiting...
Oh, btw, the board is about to go EOL.
