I have decided to retire my iMac G5 from active use by me. My workplace has a significant Mac presence in the graphics department, and they have indicated that they would have a use for the iMac. With that in mind... what would be the best way to set up the iMac for their use? I suppose I should be a bit more specific, so here are my questions: Obviously, I need to format the drive. Should I use the 7-pass secure erase, or the 35-pass one? Should I install an OS on the internal drive? Assuming I install an OS, which version? Tiger (what the Mac came with) or Leopard? Should I create an account on the OS, or leave it at the setup screen? Assuming I create an account, should I update the OS to the newest revision level, and apply other updates? If I install Tiger, should I install Classic too? If I install Leopard, should I set up Time Machine? Finally, are there any software programs that a corporate graphics department might find useful, that I should install?
