Mac keyboard and mouse not working while other thing seems ok
I've been using Macbook air for a while, and recently I ran into this problem.
sometimes when I'm watching videos on VLC, suddenly my keyboard, mousepad or plunged in mouse all stop working, the cursor doesn't move. But the video is still playing, the clock is working, even the messages that plug or unplug USB is normal. I've tried to clear PRAM, the problem still remains.
Please help, thanks
MacBook Air, OS X Yosemite (10.10.5)
