I bought a new 15" C2D MBP 2.33Ghz a couple of weeks ago, and I'm mostly satisfied with it. It had a G5 iMac 20" before that and I was happy with it too. However, I have two little annoying problems now with the MBP and I'd like to know if i'm the only one having these issues, and/or if anyone manage to solve them. Googling didn't help so far... 1) Even though I unchecked the box for: Automatically reduce the brightness of the display before display sleep", the display still reduce it's brightness after something like 10 min of inactivity. 2) Every time I make a video call with iChat, the (buildin) microphone is setting itself to something like ~75% "gain", which is WAY too low for anyone to hear in iChat (although it's fine for Skype). I see the change "live" by leaving the sound pref pane open with the mic at 100% and when I start an iChat call, it goes to ~75%. Pretty annoying! I did "repair permissions" several times, rebooted (yeah, an old reflex...) and tried to run my account with admin power (something I don't do normally) and it's all the same. Anyone has a suggestion, apart form getting used to the dimming of the display and using Skype instead of iChat for video calls? Thanks.
