The MacBook Air I bought in 2014 looks like it is in tip-top condition. It turns on quickly and easily. It runs Safari, Chrome, and Firefox just fine. But if you want to use Microsoft Word or Teams, you simply can’t.

It’s not that Microsoft products don’t work on MacBooks — I used Microsoft Word on my MacBook for years. The problem is that, even though I am all paid up with Microsoft to download and use the latest version of their products, the Microsoft software updates for these programs are incompatible with the operating system on my computer.
