[QUOTE="harryb2448, post: 1611255, member: 42497"] If you are referring to the 20" Early 2009 iMac, suggest you purchase Snow Leopard OS X.6 DVD from Apple Online for $20.00. Boot from that and format the hard drive and do a clean install. Of course everything on the drive will be wiped so if you wish use an external drive to make a backup. If you havce an Apple ID you will be able to download a free version of Mavericks after updating OS X.6.? to OS X.6.8. Running Mavericks you will find maxing the memory out to 8GB will improve how your iMac runs. For what it is worth whenever you purchase a second hand machine, fomrat the drive and do a clean install. [/QUOTE]
