If you have EVERYONE's CPU on the guild that COULD be a lot of hashing power if combined.
No it wouldn't. Please check your numbers. 10,000 of the most powerful CPUs today amount to about one S3 which is 440GH. For a pool with 13,000,000 GH, do you honestly think the pool operator would risk his reputation for that much more?
Hell, I would hope not.
Just didn't make since to me
Stil don't understand WHY it would take up 99% of my CPU and send my cooling fans to blazing?
The reason they would turn on is to cool the CPU or GPU.
I looked at the "Activity Monitor" and sure enough, it was the CPU.
I wish NOW I had taken a picture of my activity monitor with my iPhone to prove it to you.
