Hi there! I see you’re having trouble logging into the Atmos Rewards app on your Mac running OS X 10.15.7. Could you share a bit more about what's happening when you try to log in? For example, are you getting an error message? Do you have trouble entering your credentials, or does it seem stuck somewhere? That info will help me guide you better.

In the meantime, here are some initial steps we can try together to troubleshoot this login issue on your Mac:

1. Check Internet Connection: Make sure your Mac has a stable internet connection. Try loading a webpage to confirm.

2. Clear Browser Cache: If you are also trying the web version and not just the app, cached data sometimes causes login problems. On your Mac's browser (Safari or Chrome), clear the cache and cookies:
- For Safari: Go to Safari > Preferences > Privacy > Manage Website Data > Remove All.
- For Chrome: Chrome menu > More tools > Clear browsing data > choose “Cookies and other site data” and “Cached images and files” > Clear data.

3. Verify Login Credentials: Double-check your email/username and password. If you’re unsure, try resetting your password via the official reset page: https://www.alaskaair.com/atmosrewards/account/reset-password/

4. Reset Password if Needed: Even if you reset before, sometimes doing it fresh from a desktop browser can help, as password resets sometimes don’t propagate well to the app.

5. Update App: Since you have a Mac, check if there is any update to the Atmos Rewards app in the App Store. Run the latest version if available.

6. Try Logging In from Another Device or Browser: This can help isolate if the problem is specific to your Mac or app.

If you’ve already tried any of these, let me know which ones, and we can dig deeper — like checking your account status, or if there’s a temporary issue with Atmos Rewards servers. Also, have you noticed any app crashes or being asked repeatedly to reset your password? These have been reported by some users too1 9.

Let me know what you’ve tried so far or any error messages you see!
