Hello everyone. I'm new in Mac, and new in this forum.

I got a MacBook, builded in 2007. It have Tiger, but I want a leopard desktop. What can I do?

Thanks, and sorry for my Inglish. I'm from Cape Verde (Portugues)

Your English is ok. We can understand it.

You have to get the root password from your friend. I think you can install leopard and that will let you set a new password.

Regardless of the password situation, you need to buy Leopard install discs in order to install Leopard.

Buy the retail version of Leopard and do a completely fresh install (erase and install) and you get to reset the admin password too.
