I am unable to open app designer. I am running Mac OS Sierra with MATLAB 2016b. When I click on opening a new app designer script a MATLAB window icon appears in my dock, but a window does not appear.

I was having the exact same problem (2016b, OS Sierra), which appeared when I had entered full-screen mode while connected to projector. In MATLAB click on new app designer script or open existing mlapp file, icon should appear in the dock. Then Menu->Enter full screen, app designer will show up, if not, swipe on your trackpad until designer window pops out, then reset it by closing MATLAB Window from the top menu. Worked in my case. Btw I tried changing the matlabpref.mat as suggested by Sean, it did not work itself, but there still might be a correlation with my solution as I didn't change the setting back.

I had this issue on Windows 10. This answer worked for me.
I hovered over the problematic window in the dock, right-clicked on it, and selected Maximize.

Monika Jaskolka's comment within the question worked for me:
Windows 10:
- Hover over the MATLAB icon in the task bar - wait for windows to show, including the missing app designer window,
- Right-click on app designer window, and select Maximize.

I found that deleted the MATLAB preferences folder resets everything and it works properly now.

cd(prefdir)
load('matlabprefs.mat')
What are the settings in
Preferences.appdesigner
They should look something like this
ans =
struct with fields:
ShowIntroDialog: 0
Position: [1 1 112 0]
Maximized: 1
ShowCodeViewTips: 0
ShowCompatibilityDialog: 0
If not: Try, changing Maximized to true or Position to something like mine above, save back to matlabprefs.mat and restart MATLAB.
