Stocks App not working on Mac OS Big Sur

I met the same issue and managed to solve it.

1. Open Finder, and click "Go" in top bar.
2. Select "Go to folder" and input "/Users/YOUR_USER_NAME/Library/Containers/com.apple.stocks/"
3. Rename the "Data" folder to a backup folder.
4. Lauch stocks again. It will create a new Data folder.

This happened to me after upgrade. But before upgrade I hard rebooted my computer. So, not sure if it's caused by hard reboot or upgrade. It seems that the app's configure files were broken. Rename "Data" directory let it create a new set of folders and configure files.

There may be some 3rd party software interfering with the app. Download and run Etrecheck. Etrecheck is a diagnostic tool that was developed by one of the most respected users here in the ASC and recommended by Apple Support  to provide a snapshot of the system and help identify the more obvious culprits that can adversely affect a Mac's performance.

IMPORTANT:

Before running Etrecheck assign Full Disk Access to Etrecheck in the Etrecheck's Privacy preference pane so that it can get additional information from the Console and log files for the report:

Also click and read the About info to further permit full disk access.

Copy the report

and use the Additional Text button to include the report in your reply.

Then we can examine the report and see if we can determine what might be causing the problem.

Thanks for testing this issue in safe mode.

Do you connect to VPN, or any other private networks? If so, disconnect from those, and connect to a Wi-Fi network.

Since you're not experiencing this in the new user account, this may be related to software opening during login. Check your login items with these steps: 

• Click the Apple menu > System Preferences. Choose Users & Groups. 
• Select the Login Items tab. Remove any programs listed there.

Have a great day!

Hello FloydFurillo,

Welcome to Apple Support Communities! It sounds like there is an error when you try to access the Stocks app on your Mac. We're happy to assist.

You've done some great steps to test this issue. Please continue with restarting your Mac in safe mode: How to use safe mode on your Mac 

Safe mode prevents your Mac from loading certain software as it starts up, including login items, system extensions not required by macOS, completes a basic check of your startup disk, and clears cache. Open Stocks, and check for the error. Then restart to exit safe mode, and test.

Keep us updated on the result.

Cheers!

If you can't see a "Data" folder in "~/Library/Containers/com.apple.stocks/", that may be caused by other issues ( permission issue for example).

When you launch Stocks App, it should create "Data" folder. Stocks will not work without this folder. Clean this folder will make stocks to start like a new installed App.

I have the same problem of Stocks app not working ("Stocks Unavailable") after the latest macOS Big Sure update (v. 11.2.3) in March 2021. It is broken for many days, and many tries and restarts haven't helped at all. Please fix that bug in the next update.

I'm having the same issue. I cannot access Stocks from my admin account but am successful using a Guest account.

Same issue.

Spent hours with Apple Support / redownloaded Big Sur still not working very disappointing Apple!!!!!!!

The "data" file does not appear?

OK I wound Up getting there and have got it working with the Containers lead thank You!

this is great, thank you so much! Got it working again !!

You made my weekend! This solved my problem. In my case, it was also on this path just like FloydFurillo mentioned.

/Users/YOUR_USER_NAME/Library/Containers/Stocks/

• Rename or delete Data file
• Relaunch Stocks app once (to create Data folder; stocks seems empty, was in disbelief)
• Relaunched again and it welcomed me with the intro screen! ...Celebrating now.
