And in this year, Apple will release macOS Ventura for all Mac machines. Numerous users will like to install new macOS to benefit from its new features.

How does macOS Update work?
Once you've turned on the automatic update notification on your Mac, it will alert you each time Apple releases a new macOS version, regardless of how minor. You can install the most recent version of macOS by going to the Apple menu > System Preferences > Software Update.
Update Now denotes upgrades to the same version of the current operating system, for as from Monterey version 12.1 to Monterey version 12.2.
When two versions are updated, such as from Catalina to Big Sur or Monterey, it is referred to as "Upgrade Now."
Both updating methods will keep Safari, Messages, Music, Photos, FaceTime, and the Calendar current. The entire process of downloading and installing macOS Monterey on a MacBook is predicted to take 35 minutes to several hours. It depends on how well-functioning and healthy your Mac disk is.
Although updating regularly is safe for your data, you should still make a backup before choosing either of the update options! Never put your faith in a machine to keep your data safe. Belief in oneself.
