Lately I've had nothing but trouble with Safari and YouTube! Videos play but my CPU usage has spiked anywhere from 80-100% during even a 240p video! Its crazy! :/ I have the latest software updates too. Also I can't go full screen, only standard or large player in YouTube...not cool...anyways I posted my activity monitor screenshots of when it was happening a few minutes ago again...its just frustrating...my computer gets really slow...I mean I can encode a BluRay and work fine but YouTube makes my MBP crawl! :O Help?
