Hi there! I understand that your MAC.BID app is opening up but then crashing shortly after. Let’s get this sorted out together.

To start, could you tell me if this started happening recently—maybe after an update or a system change? Also, do you see any error messages when the app crashes? That info will help me pinpoint the cause.

Meanwhile, here are some initial steps we can try on your macOS 10.15.7:

1. Restart your Mac: Sometimes a simple reboot can clear up temporary glitches.
2. Update the app: Check if there’s an update available for MAC.BID in the App Store or the app’s website. Running the latest version is best for compatibility.
3. Check available storage: Low disk space can cause apps to misbehave. You can check this by clicking the Apple menu > About This Mac > Storage.
4. Clear app cache or preferences: Sometimes corrupted settings cause crashes. You can try deleting the app’s preference files by going to Finder > Go menu > Go to Folder, enter ~/Library/Preferences/, find files related to MAC.BID (usually named something like com.mac.bid.plist), and move them to Trash.
5. Reinstall the app: If the above steps don’t help, delete the app completely and download/install it fresh.

Please try these and let me know if the issue persists or if anything changes. We can dig deeper if needed!
