Ok, so you might as well say I'm a Mac newbie. I used one almost 20 years ago, and not since. I am pretty handy with a PC though. So, here's my situation. I went to a yard sale over the weekend, and purchased an iMac for $5 for my daughter. She's 8, and loves being on the computer, and I figured for the price, it would be well worth it for her. After all my research, it appears to be a G3 iMac, running OS 8.5 Getting this computer second hand, it has lots of stuff on it that I don't want there for my daughter. So, I'm trying to figure out how to either upgrade the OS, or if there is an easy way to do a reinstall or recovery. The hard part is that of course, I got no disks with it. So, my first few questions are... 1. Is there a simple way to do a recovery/restore without the disks to clean up the computer? 2. Is it in my best interest to upgrade the OS? 3. And if so, what would be the best OS that will run well on the machine? Thanks.
