I will like to upgrade my iMac Late 2006 cd to a 16GB and 1TB. I want to use it for (CHE) Ethical Hacking training. I already own a Mac Pro and I have it prepared already, but I really need this iMac to perform with Tor. Does any one know if is possible to upgrade it? and if not 16GB until how much memory and storage I can updated? I've seen that in the information it says max 2GB but I don't think that's accurate. I've seen people do wonders with their computers and made them super speed. Please let me know. Thank you.
