I am trying to use GitHub actions to test my Kivy application on various operating systems. I am having trouble however running the app on MacOS operating systems and keep getting this error:

INFO     kivy:__init__.py:67 Window: Provider: sdl2
CRITICAL kivy:__init__.py:99 Window: Unable to find any valuable Window provider. Please enable debug logging (e.g. add -d if running from the command line, or change the log level in the config) and re-run your app to identify potential causes

I am able to get it working on windows and linux runners. Does GitHub’s MacOS runner not support OpenGL or is there a way to resolve this?

My test application is:

from kivy.uix.label import Label
from kivy.app import App


class SimpleApp(App):
    def __init__(self, **kwargs):
        super(SimpleApp, self).__init__(**kwargs)
        self.text = "Hello World"

    def build(self):
        return Label(text=self.text)


if __name__ == '__main__':
    SimpleApp().run()

My testing code is:

import unittest
import time
from functools import partial
from kivy.clock import Clock

from simpleapp import SimpleApp


class Test(unittest.TestCase):

    def pause(*args):
        time.sleep(0.000001)

    def run_test(self, app, *args):
        self.assertEqual(app.text, "Hello World")
        app.stop()

    def test_example(self):
        app = SimpleApp()
        p = partial(self.run_test, app)
        Clock.schedule_once(p, 0.000001)
        app.run()


if __name__ == '__main__':
    unittest.main()
