>Might be worth checking if you have any external hardware causing issues? I have no external drives at all. Well I do but , because they are usb and turns out for this brand new Mac that should be 'everything I ever need' apparently I need to buy a huge adapter sizing like 'half of this Mac' to make it work with peripherals.
