Can any MAC users offer advice on "Kernel Tasking" ...i'm sooooo not a hardware person. I have a first generation MacBook Air and have never had a single problem with it in 4 years... until the past couple of months. This issue started after a FireFox update, but that might just be coincidental, because the problem seems to occur no matter what browser i use. What happens is, my system gets bogged down, starts running like it's been dropped in quicksand and then starts to heat up. I know the bogging down isn't a result of overheated, because the temp doesn't rise till AFTER the bog-down. Ever time this happens, checking the activity monitor, i can see the problem is Kernel_Task! I can watch it go from taking up 5% of my CPU to.... GET THIS... 175% of the CPU!!!! 175% how is that even possible? All the information i've found has been too techie for me. While i'd like dumbed- down answer to: do i even need Kernel Task? if not, can i somehow trash it? is it causing damage to my system? (or just my temperment) and 175% what's up with that? (some kinda fuzzy math) But all i really need to know is, HOW DO I MAKE IT STOP? this screen shot may not tell you anymore than what i've already mentioned, but just in case, here it is.
