n2nn2n Posted December 5, 2014 Share Posted December 5, 2014 Thought I'd share this. I upgraded from Mavericks to Yosemite on my system with a Gigabyte Z87x-UD5 TH (F5-beta firmware) and was tinkering around and saw that my USB3 ports were not working well. There was about a 2 minute delay on keyboard and mouse (if plugged into USB3 port, it was fine with USB2) at the Mac OSX Login screen. It was fine at bios and fine at the clover boot screen. USB3 was never that stable under Mavericks to begin with. Took a while and after several re-install. I decided to reset my CMOS (pulled out the battery). The Bios was simply set at with Optimized Default setting. Seems to have fixed the problem. USB3 stable and no lag with keyboard and mouse. Logitech Webcam not crashing anymore Added boot-args= -gux_defer_usb2 , NOT using GenericUSBXHCI.kext. Also, Audio, Wi-Fi, Bluetooth and Ethernet all now work off motherboard! Trim Enable: Clover config > Kernel and Kext Patch > IOAHCIBlockStorage > Find : 004150504C452053534400 Replace : 0000000000000000000000 Audio : toleda/audio_CloverALC WiFI : Clover /kext/10.10/WifiInjector.kext Ethernet: Clover /kext/10.10/AppleIntelE1000e.kext Bluetooth : BTFirmwareUploader.kext using Pokenguyen Hackintosh Vietnam Tool 1.8 NOTE: Bluetooth detects Magic Trackpad but won't detect the Magic Mouse. I don't use the magic mouse, but was just testing. Hope this helps someone. And thanks to all who made this possible Link to comment Share on other sites More sharing options...
