Updating Mac OS on a 2011 MacBook Pro

MacOS 10.13.6 High Sierra is as far as that 2011 MacBook Pro can be upgraded because it's old and obsolete.

Don't shoot the messenger!

I have a 2011 MacBook Pro with 16 GB RAM. With 10GB of that memory available. Are you saying that this computer is completely obsolete? Everything runs really slow. Google Chrome and Safari even has a hard time loading pages. I guess that’s what you guys. Do you create new things to make your old products obsolete so we have to buy new ones.

that’s just rude .
