I just got my MacBook last week and I really like it - great design, great OS, fast, etc. However, there are some flaws which are annoying me. The first problems are the already heavily discussed mooing and whining - my MacBook is mooing after a few hours working on it (not immediately after I turn on the computer) and sometimes whining when it is charging the battery. I really hope that a Firmware update will solve these problems with mooing and whining. What I am more concerned about is that my MacBook looses the WLAN connection frequently, although I have full reception and the Router is properly working (other computers in the network don't have this kind of problem). Does anyone know something about issues with the airport in the MacBook? Perphaps one important observation is that the airport can't even connect to the WLAN after I ran windows xp (via bootcamp) and restart the computer to run OS X. If I want to connect to the WLAN in OS X after I had windows running, I have to shut down the computer and restart it to OS X. But also when I run OS X in the first place and the MacBook is connected to the WLAN it may work for one or two hours and after that it often looses the connection. Does anyone have the same problems?
