Upgrading to macOS Sierra

It won't be long before Mac users are faced with the decision on whether to upgrade to macOS Sierra. If you decide to do so, here is an article you will want to read to learn more about how to prepare for the update. Probably nothing will go wrong with the update, if you do it, but it's a great idea to have a bootable clone of your existing OS to fall back on if something should go wrong. The article mentions one such app, and I use Super Duper, although I've never had to try and use it to see if, in fact, it actually works.
