After installing the latest Macbook Air *update* I discovered that my CPU stucks at 800MHz all the time. The only way to get around this issue is to actually use Coolbook. If I use coolbook to set the CPU for example to 1.6GHz and 1 Volt it will easily go up to 107 Degrees and this is not the way its supposed to be. I heard from people without any issue so I asked the local Apple Store to check on it and then they replaced my logical board and everything around it. Still the same. Any idea?
