I used to use an app called Afloat that let me pin windows on top of all other windows on the Desktop. However, Afloat stopped being maintained at some point and it doesn't work with more recent versions of OS X.

I then used an app called Compulsion, which installed as a SIMBL plugin but then that stopped working with OS X El Capitan.

Is there a way to get either of these apps to work with OS X El Capitan? Or is there another solution I can try?

    The top of the link you shared to Compulsion mentions it works in OS X El Capitan. Is this misinformation? Apr 30 '16 at 1:23

Try using Helium. It uses a 'customizable translucency' to keep a window on top of other windows. Plus, it won't intercept mouse clicks on top of it unless you want it to.

As of now, it only supports a browser window but the question doesn't indicate if that's a requirement of the OP or not.

    This is great if all you want to do is browse the web. Otherwise, not so much. Apr 30 '16 at 1:21

    @LukeTaylor which is exactly what I indicated in my answer so I don't see the point of your comment.

I suggest trying kwm https://github.com/koekeishiya/kwm

From my experience, the whole intention of having one window always on top is to read/compare/reference to it while working on another app.

"Tiled window manger" solutions works much better for this purpose. After having tried Athethyst https://github.com/ianyh/Amethyst, I came to kwm. I find kwm offers a better way of configuration. It relies on a config file. After installation, which takes a bit more work then Amethyst, and reading through the sample config file, you already feel yourself a poweruser already. So It's worth to try.

A note though, when I start doing advanced fancy configuration, kwm starts having quite some hiccups.

Edit: kwm is now called yabai https://github.com/koekeishiya/yabai

  • I used to use this all the time with KDE, it's useful for everything. Comparing documents, but also watching a movie on top, having a terminal always handy, or your file manager.
