You are probably aware by now that Apple is making a change in its operating system, and its name, as well as adding some new features. Here is an article that provides a summary of the changes. One item that caught my attention was that Apple Pay is coming to macOS. If retailers, such as Amazon, adopt this, it could be a mixed blessing. On the one hand, you wouldn't have to fill out a form and enter credit card info in order to make a purchase. It would be quick and easy to spend money. On the other hand, if, say, your iPhone is lost or stolen you better have a good password on it. Otherwise, someone may use your phone to go shopping. Another interesting feature is that your iPhone can unlock your Mac. Not a big deal, certainly, but kind of neat.
