I want my 9 year old son to have the current iMac I'm trying to update (the one found in the trash). But that computer already had El Capitan installed. iMac bought for $60 on Craiglist (El Capitain). I was able to offer my 13 year old son an old 27in. My two young songs are doing school online all year. Willing to buy a dual layer burnable DVD if I must. I've spent maybe 20 cumulative hours trying to successfully update to 10.6. I likely don't know enough / doing something wrong. I can't seem to unzip the file for download #1. I've tried doing it myself but I can't get passed the download page.
Long story short (more details in background story on the Reddit post if interested), I need someone to provide me with baby steps / for dummies version on how to upgrade my iMac to 10.6 using the software available on this page. To be honest, I found it in the trash, but it works perfectly. ) asking how I can update my mid-2009 iMac with Mac OS X 10.5.8 Leopard installed. This site / specific download was recommended to me after I posted a 'help me' post on Reddit (.
