Hi! I understand Forecast Bar isn’t opening on your Mac running OS X 10.15.7. Let’s work together to get it up and running.

First, just to get a clearer picture—when you try to open Forecast Bar, does anything happen at all? For example, does the app attempt to launch but then close right away, or does it simply not respond? Also, have you recently updated the app or your Mac system?

Meanwhile, here are some steps you can try starting from the simplest:

1. Check for App Updates: Open the Mac App Store, go to the Updates tab, and see if there’s an update available for Forecast Bar. Sometimes an outdated version can cause the app not to open properly.

2. Restart Your Mac: A simple restart can clear temporary glitches that might prevent an app from launching.

3. Force Quit and Relaunch: If Forecast Bar appears in your Dock or Activity Monitor but won’t open fully, try force quitting it (via the Apple menu > Force Quit or Activity Monitor) and then open it again.

4. Delete and Reinstall: If the above don’t work, try deleting the app from your Applications folder (drag it to Trash), then reinstalling it fresh from the Mac App Store.

5. Check Permissions: Occasionally, permission issues can block apps from opening. Right-click Forecast Bar in Applications, choose Get Info, and make sure you have the necessary “Read & Write” access under Sharing & Permissions at the bottom.

If you’ve tried some of these and it’s still not opening, let me know which steps you’ve done and any error messages or behaviors you’ve noticed, and we can dig a bit deeper.

Does that sound good so far?
