I have an old 2007 Macbook. I tried to boot from a usb. Turning on the laptop while holding down 'alt' to get the boot menu. The usb prepared with Rufus/dd/cat when plugged in, makes the laptop stay in a white screen. If I hold down 'alt' without a usb attached then the boot menu appears and gives only the hdd to boot from.

Issuing sudo in the terminal makes it to ask for a password I don't have. So my only guess (first time ever working with Linux on a Mac; regular user of TC) is that the laptop is 'account-locked' and that makes it impossible to boot from usb drives/cd/dvd (optical disc tried as well). The account the laptop boots into is a guest account.

Any ideas on how to make this laptop run Tiny Core? or is it just paper weight at this point?
