This is probably very basic but I don't know how to do it... I have an iMac (2007) running Leopard. I have an iBook (2004) running Tiger. They both share my home wireless network. How can I best share documents between them? Eg how can I browse the hard drive of each machine from the other- ideally without entering passwords etc every time? Additionally, the iMac is connected to the printer (because it is also a scanner); can the iBook share the printer too? Thanks in advance!
