I am a IT Manager for a non-profit organization in Milwaukee, WI. (you can Google my name) and we recently received two Mac G4 computers. I have never worked on or used a Mac before, so this is a learning experience. Starting off, the o/s and application software has been removed from these machines. When I first turn the computer on, it asks for a password which I do not have. I do not have the Mac o/s so I intend to install Linux and Open Office on these machines as we do not have the funds to purchase it. Any suggestions on what to do to: 1. Get past the password. 2. Install Ubuntu 7.10 Linux and Open Office for Mac. Thank you in advance for any help you may offer.
