Hi guys! I am not a mac-savvy person yet, switched from pc several months ago and would like to share my experience which barely can be named successful. My specs are as follows: Mac Pro 2.66 Quad-Core Intel 3Gb RAM NVIDIA GeForce GT 120 Mac OS X v.10.5.7 This machine was bought in March. Since then Kernel Panic happened 3(!) times. Some apps (mostly Safari 4.0.1) crash frequently and almost after every restart Trash contains recovered files. Some apps don't crash but freeze e.g. iMovie when exporting a project. Luxology Modo (3D software) doesn't start on this mac at all - it crashes at start. I widely used this app on pc and it's a bitter pill to swallow not having it worked. Recently I found out the latch is broken so I can't open a lid, and one of the usb ports stopped working. Is it enough to give one nightmares? I am under AppleCare and is sure going to make an appointment very soon. However I am under strict contract obligations now and can't afford to let this machine be repaired for days. I wonder if anyone had similar experience with his/her mac? When I eventually speak with a genius should I insist on complete replacement? Does Apple provide money back policy? Given all these circumstances I seriously question this shift to Apple platform because it turned out to a mess. I can't fully concentrate on my work. p.s. The only hardware which worked perfectly for me was Apple Cinema Display '24. This monitor is second to none.
