Just bought a mac for first time..I have a few questions..I went to youtube and had to download flash..after I installed it , it put a flash icon on my desktop..I right click and clicked eject? what exactly did i do? why did it put it on my desktop..I was expecting to see a delete option or something..I guess I need to learn the mac file structure..where do I see a list of folders? when I download something where does it put the file? anything to get me going would help out..I'm familiar with linux and unix so I'm sure it will just take some getting used to, as like most I'm used to using windows as my personal..How do I force the mail icon to ask for a password so that someone that clicks on the mail icon is forced to enter a password?
