I have a late-2009 2009 iMac, the. The specs are in pic below. This machine got a new hard drive last year and is running 12GB of memory, yet it often lags and is not as zippy as I would like.
I am curious if there is anything that can be replaced or upgraded to make it perform like a newer machine or are the un-upgradable parts just too long in the tooth? Thanks for the advice.
