I don't know what got into me, but I decided I could buy a Mac computer after working on Windows my entire career, and just pick it up!! What is that about an old dog and new tricks?? 🙃 I immediately ordered this for my Macbook, and surprisingly I have "somewhat" taught myself to use a Mac; but I had to have Office there just to give me confidence. I haven't had to use it much, but when I did it was truly a life-saver. It works well and is very easy to install for those of you who want to really decide which operating system is the best after all!!
