Hi there! I see you're having trouble logging into the Rogers Xfinity (Shaw) platform on your Mac running OS X 10.15.7. Let's work through this together.

First, could you tell me a bit more about what happens when you try to log in? For example, do you get any error messages, or does the login screen just refresh? Also, are you using the app or accessing the platform via a web browser?

In the meantime, here are some basic checks we can start with:

1. Double-check that your username and password are typed correctly. Passwords are case-sensitive, so make sure the Caps Lock key is off.

2. If you’re unsure about your login details, you can reset your username or password on the Rogers Xfinity website.

3. Since you’re on a Mac, try clearing your browser’s cache and cookies, especially if you’re logging in via a web browser. Sometimes old data can cause login issues.

4. Make sure your Mac’s software is up to date with any available updates for OS X 10.15.7, and if you’re using an app, ensure the Rogers Xfinity (or Shaw) app is updated to the latest version.

If these steps don't resolve the issue, please share more details about the problem’s behavior, and we'll dive deeper into the next steps.

Are you comfortable trying these out and letting me know how it goes?

i can log into rogers (with shaw) but I can't access xfinity to watch the shows that I'm paying for

Thanks for clarifying! So you can log into your Rogers (Shaw) account but are unable to access Xfinity shows despite paying for them. That helps narrow things down. Let’s check a few things specific to accessing Xfinity content on your Mac running OS X 10.15.7.

1. Login Credentials for Xfinity Stream: Sometimes the Rogers/Shaw login works for your account portal but the Xfinity Stream app or website requires you to use the same credentials. Are you logging into the official Xfinity Stream site or app using the exact same Rogers/Shaw username and password? It needs to be a subscribing TV customer account authorized to access the streaming content.

2. Subscription Verification: Confirm that your Rogers account is recognized as a TV subscriber eligible to watch Xfinity streaming content. If possible, check your Rogers account details online to ensure TV services are active and linked properly.

3. Web Browser and Cache: Since you’re on a Mac, if you’re using a browser to watch, try clearing your browser cache and cookies or try a different browser (Safari, Chrome, Firefox). Old cached data might block content access.

4. Location Restrictions: Xfinity services may have regional restrictions. Make sure you are within the coverage area or using the service in Canada where your Rogers/Shaw subscription applies.

5. App Updates or Access: If you are using an app, ensure it is the latest version. For Mac, you might be using the browser interface; in that case, check that Flash, cookies, and JavaScript are enabled, which some streaming requires.

6. Try Logging Out and Back In: On the Xfinity Stream portal, log out completely and log back in with your Rogers/Shaw account details.

If you want, I can guide you step-by-step through any of these or check more specific settings with you. Does any of this match what you’ve tried so far? Or are you using a particular app or just the website?
