Right here in the screen capture:

If the fan on my MacBook Pro starts kicking in… or if it gets slow… or if I look at the CPU monitor and see it jacked to near 100%… all I have to do is open my Activity Monitor and…
99% of the time it’s an issue with Flash!
Now, granted, it’s probably not “Flash”, per se, but rather “a website that isn’t using Flash properly”. Or “a website that has a poorly written Flash app.”
But that’s perhaps the point… so many websites out there have poorly written Flash apps!
The good news is – and THE reason I use Google Chrome – is that I simply kill off that process and my Mac goes back to being snappy again. Still, it’s annoying.
How about you? If you’re on a Mac do you find Flash sites jack up your CPU?
If you found this post interesting or useful, please consider either:
Since 99% of the Flash on the web is useless distractions, I used AdBlock to block all Flash by default.
I’m like Moshe (but with a different browser). I use Camino’s Flash blocker. I open sites and see a little squiggly (ƒ) in a circle. It’s very calming (and no change to the CPU/fan).
Can’t say I’ve noticed it. My MacBook Pro fan comes on very rarely — and only when I process video.
