Hi guys, just received my 6-core today! i'm installing everything on it, Adobe...etc but i have a few questions and hope you fine people could help me out: - i did all the software updates and when i look at "About this mac" it says Mac OSX 10.6.4, is this the latest and greatest osx version? - I have my stereo connected to the back of the MacPro are the following settings correct "system performances- sound: output = Line out - Audio line out port input = none Reason i ask this is all the sound is playing ok except while installing Adobe there was this loud "POF" trough my speaker set ? after about 50Min again this loud POF? is this some kind of faulty hardware problem or ...? - Final question: when i install VLC player ot anny other software there is this file that shows up on the desktop ...after installation can i just remove this? because after i remove it and try to use VLC it says it can't find the player. sorry if my questions seem a bit stupid, the most i'm concerned with this weird loud PAF trough the speakers or is this nothing to worrie about?
