I just want to say hi to everyone on the forum. Your advice has been great leading up to getting my pb. The adjustment has been a little weird, but i have had my pb for 3 days, and i can say safely i do know how to navigate through most of the OS. One thing that is pretty impressive about the mac is that you really need no formal training. I had no clue what advanced features MS had until i got my MCSE last year. I can really see now why people switch and really enjoy working and surfing on the Mac. Everything has worked as it should, and no dead pixels. I do have 2 issues that are kind of throwing me for a loop........... Maybe someone can point me in the right direction. Can anyone point me in the right direction in finding some info on how the mac file system works. I know its something along the lines of mounting and dismounting drives to use them............. I went ahead and bought the OSX missing manual........ i cant find anything on file structure or file systems....... any help would be great...............other than that im a happy camper!!!!!!
