Mac users CAN'T... that's one of the down on all Macs, besides the Mac Pro which is monstruously costly, you can not customize anything on a Mac... that's why i bought the Mac-mini (mini-mac for me) as it's only the computer box... i have my old monitor, my prefered keyboard and mouse, speakers etc... but i can't change a thing on that computer but the size of the HD or the RAM...

i prefer PC for the instance of customization... i may have a 500Gigs solid-state HD on my computer, i'd like to have two.. lol no place for it. i could do it with a Mac Pro, but the box is way bigger, and that's why i actually sold my older Mac Pro... too big, it was heating my entire living room just by being open.

what i like about Windows though is the way some functions are built: if you select to shutdown the computer, it is not asking you to approve the action, as on the Mac... the logic is solid... if you reach the shutdown option in the menu, it is because you really want to shutdown, no error.
