I just got an iBook from Craigslist.com I've been using Windows since the 90's,so this is my 1st encounter with Mac world.I have a few questions until I get used to it. I bought a OX Tiger 10.4 on Ebay so I could reformat the HD,only came with 1 DVD disc,is this right ? Just like in Windows what equals Crlt+Alt+Del in Macs ? How can I disable iDrive ? The are any free good app site for Macs ? Like games Word,games etc... Do I have to worry about spyware,malware etc.. with Macs ? Anti virus will be a good thing to get as well ? Any other suggestion will be welcome !!! Thank you.
