Are you keeping your Apple computers up to date?

I was working with my Apple desktop computer today and wondered if it had any updates available. The manufacturers of operating systems release updates to the public so they can keep their computers secure and free from problems. Microsoft and Linux do the same thing. On my Apple computer, I checked for updates by clicking on the Apple icon in the upper left-hand corner of the main menu. Next I clicked on software update and that’s all it took.
