Is there any way too install a Mac OS with out a bootable flash drive or dvd disk? I have one macbook with 10.4 tiger installed and another one with 10.5.8 leopard. I want too install the Mac OS leopard into the Mac OS tiger...is there a way too do that if I connect the two macbooks together with some sort of cable? I remember someone saying on here that this is one alternative way of installing a OS on another macbook if you do not have a dvd or bootable flash drive....If you can what cable is needed so I can buy it and what are the steps too do this. thanks!
