Help: USB works only without kernel caches


USB not working with caches.

Using clover. HP Compaq dc7900 cmt

OSX: 10.9.3

It started when i updated to 10.9.3.

I also have this problem with the 10.10 installation but because it only boot to the caches, i can't install.

I have tried: USBBusFix, the legacy flag, using clover usb fix.


Please help, I don't have any problems with my mac right now, but the boot time is long and i really need 10.10.

Thanks :)

I'm happy to let you know i have found the solution for this problem.

1. Remove AppleHPET.kext

2. In Terminal

sudo rm -r /System/Library/Caches/com.apple.kext.caches

3. Use kext wizzard to rebuild cache / repair permissions

4. Reboot


It should work now.
