Recently—a day or two ago—I noticed that my MacBook Air was emitting a low-pitched hissing sound, as if a fan were running. I first noticed this when I had been processing photos in Lightroom for a while. But I’m experiencing it now and all I have open are Safari and Mail.
I ran Activity Monitor and found two tasks that were using a high percentage of CPU. One was a kernel task. The other showed the web address of The Atlantic Magazine, which I had open at the time. The percent of CPU it was using ranged between the mid-50s and the mid-90s. I killed that process, the Atlantic page was reloaded, and the fan noise has stopped. Why would a web page use so much processor capacity?
