Upgrade to IOS 15 on MacBook Pro
When I went to preferences to upgrade/update, I had the choice to either update or upgrade. I decided to update first for the security then I was going to upgrade. The update completed, but now when I go to preferences to upgrade to IOS 15, it just indicates that I am up to date, but gives me no option to upgrade. Question, how to upgrade now if I don't have the option in preferences?
MacBook Pro 13″, macOS 11.6
