Hi everyone, i have received two days ago my nMP and i am experiencing some strange "lag" and "jumps" with mouse and also the keyboard sometimes misses one or two keys when typing fast. My peripheals are razer deathstalker ultimate (keyb hooked with usb) and a logitech g700s (usb wireless receiver). Keep in mind that i have absolutely no issues when bootcamping in windows 8.1 . I run mac osx 10.9.2 . Any suggestions ? Thanks in advance.
