If you are one of those people or know one of those people that have a 2009 4,1 Mac Pro and want to squeeze another decade of life out of it, this page is for you!

I took this knowledge for granted, forgetting there’s a whole world of people out there that have no idea this knowledge exists. They don’t see this kind of information on a daily basis like this geek. But there are many Mac Pro users that are not aware of those communities or of the upgrade potential and possibilities for their Macs.

Hanging out in the various Facebook groups and other communities, I rarely run into anyone anymore that has a 2009 4,1 Mac Pro that still runs the stock firmware.
