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:
Code:sudo -s
Code:cp -R /System/Library/Extensions/AppleThunderboltNHI.kext ~/Desktop
Code:rm -R /System/Library/Extensions/AppleThunderboltNHI.kext
Code:touch /System/Library/Extensions
3. Reboot system, and the delay is gone!
Thanks to Genzai in the Thunderbolt 2.0 Testing thread here.
I had the same problem of slow boot with z87x-ud5th but removing the kext "AppleThunderboltNHI.kext" I solved
