plz upgrade MacBook Air 2007 macOS12 I request u plz
There is no such thing as a MacBook Air 2007. Apple released the original MacBook Air in January 2008. For it, Mac OS X 10.7.* (Lion) is the end of the line. Lion is ten major versions behind the version of macOS you want – and is so old that the version of Safari included with it is unable to connect to many https Web sites.
Apple released 13" MacBooks with white plastic cases in Mid 2007 and Late 2007. For them, Lion is also the end of the line. There were 15" and 17" Mid/Late MacBook Pros that fared a little better. You could upgrade them all the way to El Capitan. El Capitan is extremely outdated, and is six major versions behind the version you want to run – Monterey. Apple released the last update to El Capitan (10.11.6) in July 2016, and even Mozilla abandoned that operating system as of sometime in 2021. (No Firefox ESR feature updates or security patches, for El Capitan, since then.)
Monterey itself is set to fall out of "the most recent three" in just a few months, when Sequoia comes out. If you are thinking of replacing that ancient Mac with a new, or newer, one, I suggest buying one that is on the Sequoia compatibility list. (Even if you just run Monterey or Ventura on it to start.)
If you typed the year wrong and are not referring to one of these 2007 MacBook or MacBook Pro models, please clarify.
