Hey I need some advice on intalling Leopard. I have a PowerBook currently running Tiger, but what Option do I choose when installing Leopard? Upgrade Mac OS X Archive & Install Erase & Install I would really like to do Erase & Install... however I am 180miles away from home. this is where my Microsoft Office, iWorks06, iLife06, Final Draft, Dreamweaver and Sound Studio Discs/Serial Numbers are. Also there's noone at home who can post them to me. So doing the Erase & Install is jut not an option as I'll loose all the programmes I have on my PB. So what other option do I choose? All my personal files (e-mails, music, movies, photos) are all backedup onto an external drive - that's when I had the thought of Erase and Install - but then realised I didn't have the intallation discs to hand. thanks god i remembered. Thanks for any adive or help.
