Replace Big Sur 11.7.11 for updated Operating System.

I have an MacBook Pro using BigSur 11.7.11. Could I change that operating system to an updated system?

Unfortunately, this does not appear to be possible. You may want to have a look at the data for your exact MacBook Pro model here: https://everymac.com/systems/by_year/macs-released-in-2013.html. As far as I can see, macOS 11 Big Sur is the maximum system.


If there is a problem finding a suitable browser for certain web sites, you may want to try Firefox (the latest version still supports macOS 11 Big Sur).
