so this has happened twice in 2 days. where randomly i noticed my fans were cranking and looked up at my top bar and saw 85%/100% cpu usage. popped open activity monitor and it was safari. the first time this happened it was safari but even when i closed it the cpu usage continued. i had to reboot to stop it.

any idea why this is happening? im thinking i might need to reset pram, and whats the other one?

another thought is i have had the same safari open for a couple days. i just shut my macbook and left safari open.
