My macbook is using 100% of its CPU, all the time. The computer is not overheating, the fan speed isn't insane either (around 3400rpm when not doing much), but nevertheless the macbook needs to use all its CPU. I'm a total noob but sort of figured that this is not supposed to be like this. CPU user:70% system;29% nice:0% idle;1% Is this ok or bad? If bad, what can I do about it? I did look for this problem on the forum but that was always fan or heat related and I don't think that is the problem with my macbook. If it has been discussed before, sorry for asking again.
