Hi there! I understand you're having trouble with Vinted showing no items. Let’s work through this together to find a solution.

To start off, can you let me know if you're accessing the Vinted app or the website on your Mac? Also, have you recently made any changes to your account or your device that might have affected this?

In the meantime, here are a few steps you can take that might help:

1. Refresh the Page or App: Sometimes simply refreshing the app or the webpage can help in loading the items correctly.

2. Clear Cache and Cookies: If you're using a browser, clearing cache and cookies can sometimes resolve display issues:
- Go to Safari > Preferences > Privacy > Manage Website Data, and then click Remove All.
- If you're using another browser like Chrome, you can usually find this option in Settings under Privacy.

3. Check for App Updates: If you are using the Vinted app, make sure it's updated to the latest version.
- You can check the App Store for any updates.

4. Log Out and Back In: Logging out of your account and then logging back in can refresh your session and help resolve any errors.

If these steps don't resolve the issue, please let me know, and we can dig deeper! Are you satisfied with the solution I provided?
