I need to update my old CRT iMac and so assuming the new iMac is available in the next few weeks I will be upgrading. The question is what is the best user set-up for home use - mainly web, email, iTunes, iPhoto, iMovie and a bit of photo editing and "Office"? I was thinking of 4 users; Admin (just me) - to control the main system, Me & my wife - all our day to day, Tunes, Photos etc Kids Guest Is there value in having a seperate Admin user? Should I partition the disc to split out the OS (and app's)? What's the best way you guys have found to set-up? Thanks.
