upgrade macOS from catalina to big sur
I had MacBook air 13" mid 2012. It has a macOS catalina. Is it possible to upgrade to macOS big sur or monterey.
Question marked as
Sorry no. Catalina is the highest possible. See the following from Identify your MacBook Air model - Apple Support
MacBook Air (13-inch, Mid 2012)
Model Identifier: MacBookAir5,2
Part Numbers: MD231xx/A, MD232xx/A
Newest compatible operating system: macOS Catalina\
If you aren't already, instead of Safari you may want to consider using a 3rd party internet browser that allows running their latest version on Catalina. One option is Chrome: https://www.google.com/chrome/
