Here’s a quick accessibility tip for macOS Sierra: If you rely on the “zoom” function as much as I do, you might notice that it doesn’t seem to work as well after upgrading to Sierra. Everything looks blurry when you zoom. The issue is just that the Sierra upgrade, for some reason, turns off the “smooth images” option. Turning it back on gets things back where they should be. (I’m not sure if the Sierra upgrade always does this, or if it was a fluke. But it definitely did it in my case.)
And if you’re not familiar with the zoom function: it’s great. Better than anything I’ve tried on a Windows PC. It’s one of the main reasons why I still like my MacBook and macOS. Despite all of the silly changes they’ve made over the years, which I won’t get into right now, as I don’t want to go off on a tangent… Anyway, you can find it in the “accessibility” options, along with some other cool stuff.
On Windows, the built-in screen magnifier is ok, but really not that useful for me. Mark Russinovich’s ZoomIt is pretty good, but it’s more of a presentation tool than an accessibility tool.
