Bug: MacOS - Window Spawn Loop

What happens:

When starting FastFlix bin, after the UI loads it loads a secondary UI window. This process repeats itself (endlessly).

Attempted to kill with:

sudo killall FastFlix

While the killall was able to close all of the windows, they continued to spawn. Only solution was to remove executable permissions from the FastFlix bin:

chmod -x ./FastFlix

After removing exe permissions, the spawn loop was broken and I was able to re-add the exe permissions. Spawn loop did not start again until I manually invoked ./FastFlix again.

And I’ve confirmed that directly cloning the repo, setting up the python requirements/environment, and running the Python (as noted above)… no issues.

So here’s something really interesting… When I clone the repo and run FastFlix from python directly, there’s no issues.

git clone [e-mail]:cdgriffith/FastFlix.git
cd FastFlix
python3 -m venv venv
. venv/bin/activate
pip3 install -r requirements.txt
python3 -m fastflix

Might be a pyinstaller thing afterall…
