How to Fix Xfinity Stream Not Working on Mac?
If you know how to fix Xfinity streaming not working on Mac, you can get back to watching your favorite shows in no time.
Since there are many possible fixes, it’s best to start with the simplest.
Issues with the browser are the most common cause of Xfinity not working.
So, the first thing you should do is update your Safari browser to the latest version. Updating Safari can resolve playback issues and improve the browser’s security.
If this doesn’t work, proceed to the more advanced solutions below.
Solution #1: Enable Auto-Play on Safari
The Safari browser suffers from numerous compatibility issues with Xfinity Stream.
It’s not always evident, as it doesn’t manifest all of the time. However, when it does, it’s going to affect its streaming capabilities.
One of the possible reasons that your stream doesn’t play right away is Safari’s Autoplay feature. Turning it off can cause your browser’s video player not to work properly.
The player won’t load, and the content is not going to show up. You’ll want to go into Safari’s settings and turn on auto-play to address this issue.
Here’s how to switch on auto-play on Safari:
- On your Safari browser, click on the Safari menu item.
- Select Preferences.
- Go to the Websites tab.
- On the left column, click on AutoPlay.
Note: You'll need to restart Safari for the setting to take effect.
Solution #2: Use a Different Browser on Your Mac
Xfinity and Safari are simply two things that don’t mix well together. Don’t get me wrong, they will work.
However, there are instances when they don’t play well with each other. It could be certain incompatibilities with the settings or bugs that can cause the problem.
The best way to get Xfinity Stream to work on Mac is to change your browser entirely.
For Macs, there are dedicated streaming browsers that are perfect to use for services like Xfinity Stream.
Here’s how to get a streaming browser for your Mac:
- Open the App Store app on your Mac.
- Search for “Friendly Streaming” on the search bar.
- Select the app from the list.
- Click on the Get button.
- Wait for the download to finish and the app to install.
Note: The Friendly Streaming browser comes with a native video player, which prevents most of the issues you're going to face with Safari.
Solution #3: Remove Safari Browser Cookies and Cache Storage
Safari saves related information to make its operation faster.
If you’re streaming, your browser saves a few seconds of the content you’re watching in advance.
This is to ensure that you’re going to have a seamless viewing experience.
Sometimes this system can malfunction. One of the primary reasons this happens is whenever your storage space is full.
To fix this, you’re going to need to clear out Safari’s storage.
Here’s how you can clear Safari’s cookies and cache storage:
- Open the Safari app on your Mac.
- In the menu bar, select History.
- Click on Clear History.
- Pick All History.
- Select Clear History again.
Note: This step will also delete your browser's cookies and cache.
Solution #4: If Using a VPN, Change Your VPN Connection Settings
Are you using a VPN whenever you’re watching with Xfinity Stream? If not, you want to explore VPN use for streaming.
Although there is no problem with using a VPN, it can cause some issues as streaming activities uses a lot of bandwidth and data.
You want to make sure that you’re using the optimum settings with your VPN for an uninterrupted streaming experience.
You want to use the configuration that will give you the fastest possible connection. There are specific protocols that you can use that will make Xfinity Stream load faster.
Here’s how to configure your VPN settings:
- Open your VPN app on your Mac.
- Go to Settings.
- For the Transmission Protocol, use UDP.
- Change the VPN Protocol to 3DES, Blowfish, CAST-128, or AES.
- Reconnect to the server for the settings to take effect.
Note: For a better overall experience, you want to connect using a wired internet connection.
Solution #5: Enable the VP9 Decoder on Your Safari Browser
Whenever your Safari suffers from streaming issues, you want to look at some more advanced settings.
Your cue is when you start to experience freezes or a blank screen as you’re streaming with Xfinity Stream.
Safari uses the VP9 decoder, which is used by most streaming platforms. There are instances when this is not enabled by default, so you’ll have to check to make sure it’s switched on.
Here’s how to enable the VP9 encoder on your browser:
- Go to Safari’s menu, then select Preferences.
- Go to the Advanced section, check the Show Develop box.
- Click on Develop on the menu.
- Select Experimental Features.
- Enable VP9 Decoder.
Note: For this change to fully take effect, you're going to need to restart your browser.
Solution #6: Reset Your Mac’s NVRAM
It’s also possible that the issue causing your Xfinity Stream not working properly on your Mac is not from your browser.
There is a chance that it’s a hardware problem that’s giving you a hard time streaming.
To address this, you can look at resetting your Mac’s NVRAM or non-volatile random access memory.
This is a type of storage on your computer where default settings are stored.
Your computer’s display settings are usually stored here, so resetting this should resolve your streaming issues.
Here’s how to reset your Mac’s NVRAM:
- Switch off your Mac.
- Hold the Command, P, R, and Option keys while powering your Mac On.
- Wait for the Apple logo to appear.
- Release the buttons once you see the logo.
Note: If you have the firmware password feature activated, you're going to need to disable it and repeat the steps.
If none of these solutions help you, you also want to ensure your Mac is running the latest software.
This will eliminate any issues with your browser and streaming settings. You can contact Xfinity customer support for additional assistance.
