I am picking up a late 2006 2.33 ghz intel core 2 duo imac. What is the
most recent version of the OS that I can run?
I've already maxed out my computer's compatibility with 2 GB of RAM. That's my concern.You may want to upgrade to 4 GB of RAM. If it's compatible with the RAM on the 2010 MBP, I can sell you 4 GB for about 30 bucks. Sometimes when something just meets the requirements, you may experience a slow down. Maybe not too noticeable. But it will probably be there.
