Dock Icon for Mac App Revisited

[ttepperg]

Hi guys,

First of all, I'd like to give Pyinstaller's developers a big CUDOS;

what a great package!

Now to my problem: I have found some related threads but still

could not figure out the solution.

I have built a Python/Tkinter app, which works well in every respect,

with the following exception: When opened, the app's icon briefly

appears on the Dock and then disappears, even though the app

is still running (i.e. the GUI window is open, as it should)

FYI: The dock icon is contained within myappsname/Contents/Resources,

and from what I can tell, the Info.plist file looks fine (attached).

I'm using Pyinstaller 3.6 on Mac El Capitan.

Many thanks for any hints on how to solve this one!

Cheers,

Thor.
