Hi! I understand you’re having trouble watching movies on PureFlix. Let’s get this sorted out together. To start, could you please tell me more about what’s happening? For instance, do you see any error messages, does the movie fail to start, or does it keep buffering? Also, are you trying to watch on your Mac directly through a browser or through the PureFlix app?

Once I know a bit more, I can guide you with the right steps! But to begin with, here are some quick things we can try on your Mac OS X 10.15.7:

1. Check your Internet Connection: Make sure you have a stable network connection. You can test your speed on Google by searching "Speed Test" and running it to ensure your connection supports streaming.

2. Update Your Browser or App: If you’re using a browser, make sure it’s updated to the latest version. If it’s the PureFlix app (though mostly on mobile or TV), try to update the app to the latest version if available.

3. Clear Browser Cache (if watching through browser): Sometimes old cached data can cause streaming issues.
- Open Safari (or whichever browser you use).
- Go to Safari menu > Preferences > Privacy > Manage Website Data > Remove All.
- Restart the browser and try again.

4. Sign Out and Sign Back In: Sometimes logging out of your PureFlix account and then logging back in can refresh your session and fix playback issues.

5. Restart Your Mac: A quick restart can help clear temporary glitches with apps or browsers.

If after trying these you’re still unable to watch movies, let me know what specific behavior or errors you see. We can then go deeper, like checking for subscription/account issues, or reinstalling the app if applicable.

Does that sound good for a start?
