Hello all,I really need help.I have 2 iBook Clamshells both with 10.1 on them and I can't get 10.3 on them for the life of me.I really need 10.3 to use them as my main laptops for internet.Anyone know and tips or secrets on how to get them working and installed. The specs are:iBook Clamshell Graphite,466MHz PPC,320MB Ram,80GB HD,airport. iBook Clamshell Blueberry,300Mhz PPC,288MB Ram,40GB HD,airport. So I know that both have the right specs but it won't get past the screen after you restart with the apple logo and spinning wheel. Any help appreciated.
