There is also an issue with the font panel in Mathematica 11 under macOS Sierra. If you access the panel (Show Fonts), Mathematica 11.0 crashes. The beta (11.0.1) that fixes the graphics issue has that menu item dimmed out. According to tech support, this is a non-trivial problem. (The public beta for macOS Sierra does not fix the problem.)

If you need this functionality, I would hold off upgrading to macOS Sierra until this problem is resolved. Unfortunately, I already upgraded both my macs. Fortunately, I won't be needing to create new style sheets, etc. for a while.

It may have something to do with another discussion we had some time ago: Flickering desktop when working on OSX with MMA 11.0.0

Short answer is that "Show Fonts" is not selectable (greyed out) in Mathematica 11.0.1 under macOS 10.12.1.

Does the "Show Fonts" problem persist after the mac OS Sierra 10.12.1 update?

After upgrading to 11.0.1, "macOS bug 2.nb" no longer causes the issue.

(Wolfram support replied they could not repro the behavior -- I wondered whether they used a MBP with Intel GPU).

However, the new attached file "macOS bug 3.nb" even more readily causes a kernel panic. On my early 2015 MacBook Pro 13 (Intel Iris 6100), all you have to do is scroll to the bottom of the document to reveal the ListDensityPlot3D. Soon after I scroll it into view, I reliably get a kernel panic.

I'm particularly interested in v9.0.1, 10.0, 10.3.1 and 10.4.1.

While past releases will not be officially called compatible with Sierra, they've all been fine in my daily use (excluding the font panel crash).

I am not aware of any Sierra-specific OpenGL regressions. These usually have more to do with the underlying graphics hardware than anything else so I would expect that, on the same machine, 3D graphics should work about the same (or better, for example the Intel graphics problem a number of people ran into in 11.0 should be addressed in 11.0.1) as in previous OS X versions.

This is the discussion on the same topic on Mathematica.StackExchange.

The previous attachment had incorrect contents. I'm now attaching the correct repro case file, "macOS bug 2.nb". There's nothing in it but a ListPlot3D graphic. Manipulate it with your mouse, and you will have to reboot your computer.
