I have a few questions: 1.) Is there an option to 'force' backup right now in time machine cause my ext. backup drive isn't always connected. 2.) I have that ^ ext drive, and a printer that I would like to hookup wirelessly. Does anyone know of a usb hub that hooks up via bluetooth??? that way I don't have a dongle off my macbook and still have everything I need hooked up. Thanks in advance!
