Max RAM on an iMac, Early 2009

post #1 of 4
Thread Starter 
A while back I got my hands on a 24" iMac, Early 2009. Unfortunately it only has 4GB of RAM; officially it supports 8GB. However, I know that there have been certain models of Apple computers (mostly MacBook/MacBook Pro) which can be taken all the way to 16GB. I wouldn't mind using this machine as a VM host for development and other tasks, so does anyone know if this model can be taken to 16GB?

Many thanks. smile.gif
