…do you mean that the iMac was bought brand new (i.e., the newest model available in stores in the 2009-2010 time frame), or did you potentially buy an older model (i.e., from 2007-2008) in the 2009-2010 time frame?īecause you have OS X 10.5.8 (Leopard) currently, and assuming that you never downgraded your OS X, you can narrow down which iMac model you have. I remember for sure that the computer was bought around 2009-2010
