How to update new version
iPhone 7 Plus, iOS 15
Question marked as
I have two things to share with you. First, it is important to understand the difference between updates and upgrades. An update is when we install a newer version of the same operating system. What OS you have installed will be found in the System Preferences by clicking the Software Update button. Second, if you already have the latest version installed, you will be notified that no update is available. An upgrade is when you install a newer operating system such as upgrading from Catalina to Big Sur. What you can install is dependent on the year and model Mac you have. Upgrade links may be found in the Apple App Store. I hope this information is helpful in clearing up any confusion.
