I'll be getting my new iMac in a couple of weeks. Hopefully all will be good with the machine. My question is how many of you iMac users are operating daily under the Admin account? I understand the reason for not doing so but was wondering if anyone has had problems doing so. I am leaning towards creating 4 accounts (root, mine, wife, guest) mainly so we can have the sys prefs to our individual liking. Installing apps shouldn't be an issue as I'll have the root/admin password. So how do you guys run/manage your iMacs? I think having multiple accounts keeps things a bit more organized. But what do you think? Also how does having multiple accounts work with Time Machine? Is every account backed up separately or is the whole disk just backed up?
