A very Slow Asrock Fatality H97 Hackintosh Hi! I've installed Yosemite (and without any customization) from the yosemite zone dvd, without any problem on my pc. Configuration is this: CPU i5 4690 RAM 12GB MB asrock fatality h97 HDD 500 GB Western Digital Sata Radeon r9 270 GPU What's the matter? My Yosemite is very slow and the graphic seems to have some glitches. The mouse pointer itself is very laggy. What can i do? Perhaps i need some drivers? Thank you in advance!!
