firmware tool for the iMac4,1 and iMac5,1 which removes the 2GB RAM limit?
read somewhere apple isn`t really into the home iMacs and are concentrating more on their phones and laptops?
No, that wasn’t the problem. Even with that firmware patch made, the processor will only ever see a bit over 3gb of RAM. It’s a fault in that entire generation of Intel chipsets - PCs and Macs are both equally affected.
