This MacBook is the first Mac I've owned (Mac user as of June 4) and I love this thing. I've discovered most of the mac-equivalents of the windows freeware I use are much nicer too (Adium, Onyx, etc). Anyway... my questions: 1) Is there any software that adds extra settings to the trackpad preferences? My PC laptop's synaptics driver had a whole bunch of sensitivity controls which were very nice. 2) My MacBook has the "mooing" issue rarely, and when it does it's very faint and it sounds like many others have it much worse. To me it sounds a lot more like light breathing. Has Apple fixed issues like this in the past with firmware updates? Can they do something in 10.4.7? If I took this computer into the store I probably wont be able to make it "moo" so I'm not sure if they would recognize it as an issue. Also in a silent room I hear a somewhat high-pitched whining noise coming from the area around the hinge. Check by going into a silent room and pressing your ear up against the rear vent. Normal? 3) Assuming nothing happens with the genius bar, what if I re-applied thermal paste myself? I know technically it would void my factory warranty but how would Apple know? I have yet to look into AppleCare. If Apple is able to tell if their hardware has been tampered with would it void applecare? Thanks.
