The Mac app fails to start. I am not even sure it actually loads spyder code before blocking, so this could be PY2APP related. I will investigate further later.
This is where I see the process stalling:

Why Spyder IDE is not opening?
This error usually appears because you installed pyqt5 with pip at some point. Now you have to uninstall Anaconda and reinstall it following the instructions in our video to be able to successfully run Spyder again. Please try that and let us know if it works for you.
Can I install Spyder without Anaconda?
While we recommend always using a dedicated environment, with Anaconda you can also run the bundled copy of Spyder from the built-in base environment.
