Thanks for that response. It is not surprising my knowledge is incomplete. That is why I am here asking questions. I have never owned an iPhone. I never had an iPad and am still learning it. I have always seen Messages on my Mac but have never used it and wondered what it did. I have no idea what SMS, MMS, or RCS is. My android phone I can text, phone call, and use contacts. I recently started using notes. Usually when I get a new computer the first thing I do is shut everything off. No iCloud. No notifications. No widgets. My old MacBook Pro, which I believe is 14 years old I think I downloaded 2 apps in 14 years. This time I am taking the opposite approach and I am turning on everything and signing up for everything. I plan on at least trying every app on my iMac and iPad. Just to see what they do. It is fun but it is a long learning curve.
