I want to completely erase an iMac. I believe it to be an early 2008. I will know tomorrow when I get to the location. It was my brother-in-laws, who passed away suddenly a few years ago. It’s been sitting since. The family are Windows users so they asked me it get it to factory settings so they can learn to use it. It was his business computer so I’m sure it's packed with stuff, but they need none of it. It’s been years since I’ve done an erase and install so I asked for help. I’m getting 3 answers for the correct start up key…..command R, C, and option. Which is it? I've also been told to use NO key at start up and just let the installer ask the questions. I will most likely be installing Snow Leopard from a DVD that was purchased. My son has that installed on his 2008 and it runs flawlessly. Better than my horrible, problematic 2014! If I find it’s not a 2008 and/or it already has Snow Leopard installed and/or it’s partitioned, I may need other instructions as well. Thank you in advance!
