Hi there! I understand you're having trouble opening the Nextdoor app on your Mac. To get started, could you tell me a bit more about what happens when you try to open it? For example, does the app freeze, crash, or simply not respond at all? Also, are you using the Nextdoor app installed from the Mac App Store, or are you trying to access Nextdoor through a web browser like Safari?

Knowing this will help me guide you through the right troubleshooting steps.

app freeze using DuckDuckGo

Thanks for the extra details! So the Nextdoor app is freezing when you use DuckDuckGo, is that right? Just to be clear, are you using the Nextdoor app itself and opening links or browsing inside it through DuckDuckGo, or are you trying to open Nextdoor via DuckDuckGo’s browser or search?

Meanwhile, here are some steps you can try to resolve freezing issues that involve DuckDuckGo and the Nextdoor app on your Mac running OS X 10.15.7:

1. Restart the Nextdoor app: Completely quit the app (Command + Q), then reopen it to see if the freezing persists.

2. Force quit DuckDuckGo related processes: Since you mentioned freezing associated with DuckDuckGo, open "Activity Monitor" (search via Spotlight), look for any DuckDuckGo processes or browsers you may have running, and force quit them to clear any hung background tasks.

3. Clear app cache and browsing data: Sometimes the build-up of cached data can cause slow or frozen behavior. If Nextdoor app has an option to clear cache within settings, try that. If you are using DuckDuckGo as a browser, clearing its cache and cookies can help.

4. Update apps and macOS: Make sure your Nextdoor app and DuckDuckGo (if a separate browser) are updated to the latest versions. Also, check for any macOS updates under System Preferences → Software Update.

5. Try a different browser: If you are accessing Nextdoor through DuckDuckGo's browser or Safari set to DuckDuckGo, try opening Nextdoor in Safari or another browser like Chrome and see if the freezing issue occurs there.

6. Disable browser extensions: If you have any extensions enabled (especially ad blockers or script blockers), try disabling them temporarily since they may interfere with how pages load or scripts execute.

7. Restart your Mac: A simple restart can clear temporary glitches causing freezing.

If none of these clear the freezing, I can guide you through more advanced troubleshooting or check if there is any known issue affecting Nextdoor or DuckDuckGo currently. Could you also let me know if the issue happens only when you do specific actions in the app or just whenever you use DuckDuckGo?

Are you satisfied with these suggestions so far?
