Leopard will not install directly on a Titanium Powerbook less than 867Mhz. However, you CAN install it if you have access to any other Mac which will take a direct install of Leopard. You simpley connect the TiBook to the other Mac in firewire disk mode, load the install disk on the auxiliary Mac and specify the install go onto the TiBook disk. When you restart the TiBook, voila, OS X Leopard will boot and initialize. You can then migrate your home directory from a backup. I have Leopard running on a 667Mhz TiBook and used my Aluminum PowerBook to install it. -- Dennis Fazio dfz at mac.com -------------- next part -------------- An HTML attachment was scrubbed...
