Hi, I know it is not good to use outdated OS as they may not have the latest security path. When I took out my MacBook Pro 17" 2010, it asked me to update my software. Now, it has High Sierra 10.13.6. From wiki, it was released on November 12, 2020. Is Apple continue to provide security update for it or November 12, 2020 is the last day of any update? In other words, if I continue to use it, I am not protected from whatever security vulnerability made after that date?
