How to update my MacBook Pro (Retina, 13-inch, Early 2015) to the latest MacOS?
Here I want to install several applications that no longer support the version of OSX that I'm currently using, namely version 10.11, and when I want to install Xcode there are requirements that OSX version 12.5 or above, but when I check for software updates it can't be found or not available. os update, what is the solution that I have to do?
