With millions of daily active users, YouTube is one of the world's largest video sharing and social platforms. As for Mac users, Safari is preferred over other browsers due to its superior system integration with Apple's environment and privacy functionality. Safari is a capable browser that can accommodate anything you throw at it, even YouTube video playback. However, there are occasions when users report that YouTube does not work on Safari. If you encounter this issue, there could be a problem with the YouTube application, Safari browser, or the Mac itself. To resolve this kind of problem, you must first figure out why YouTube is not playing on your Mac browser and fix it accordingly. Although, determining the root cause of a problem is very difficult. But the good thing is that whatever is causing it, there are ways to fix it.
Check if YouTube Is Down
If the issue is with YouTube's servers, you would be wasting your time trying to use other solutions to fix why YouTube not playing on Safari. So, before moving on to other options on this list, you can determine first whether YouTube's servers are down or not. This issue has occurred recently based on the report from Express Newspapers.
- You can use a website named Down for Anyone or Just Me to check. It employs the "ping" approach to determine whether YouTube is unavailable either at your end or globally.
- Once in the webpage, type youtube.com into the empty box and hit the Return key on your keyboard.
- If it shows a message on your screen saying It’s just you. youtube.com is up; proceed with other solutions listed below.
Test Your Internet Connection
It is advisable to test your internet connection to see if your internet service is weak or having connectivity-related issues. If there’s a problem, it could result in YouTube videos not playing on Safari or any other browser on your Mac. In that case, you should use the Terminal program and the Ping command to see if your internet connection is up and working fine. Here’s how you can do it.
- On your Mac computer, press Command+Space. Then, type terminal, hit the Return key on your keyboard to open the Terminal app.
- Enter the command below and press the Return key.
If it displays positive responses simultaneously, your internet service is working well. However, if it says Request timed out or anything similar, you should contact your ISP. Alternatively, the simplest way to test your internet connection is to open another website (such as Google or Bing) on your Mac. If their homepage opens up, then your internet connection is working fine.
Restart Your Mac
This is one of the most basic and highly effective solutions for Safari YouTube videos not playing and other similar issues on your Mac. Restarting your Mac will rest the current power loop and temporary settings. This simple approach can able to resolve related minor issues in a matter of seconds.
Disable/Uninstall Safari Extensions
As a Safari user, you might have already installed some plugins to boost your productivity. Some extensions are designed for YouTube too. However, due to an internal conflict between extensions, it will result in YouTube not loading Safari. We advise that you disable all plugins and check if it resolves the problem. To do this:
- Go to Safari. Click on the Preferences and then Extensions. Here, disable all the extensions.
- Uncheck all of the checkboxes, close the window, and then try to reaccess YouTube.
Update Your Safari Browser
Safari YouTube videos not playing due to an out-of-date version of the browser. That’s why it's worth testing to see if your Safari is in the latest version. To update your Safari, kindly follow these steps:
- Go to the Mac App Store. Then, check to see if your Mac meets the minimum requirements for the most recent Safari update. For example, if you're running High Sierra, your Mac should have at least 2 GB of free memory and 14.3 GB of disk storage.
- Download and install it if all of the requirements are fulfilled.
- Relaunch your Safari and check if you can play YouTube videos properly now.
Disable Content Blocker
The Content Blocker is a Safari unique feature that allows you to authorize or disallow specific content from loading on a site. It is intended to enhance the browsing experience in Safari by blocking unwanted content. The same thing, though, may also ruin your experience. To disable the content blocker, open the YouTube website (even if it doesn't work properly). Go to Safari and then Settings for This Website. From here, uncheck Enable content blockers.
Clear YouTube Cookies and Cache
If there is a significant change in the browser or YouTube, clearing the cache and cookies can be helpful. This trick can come in handy if you face issues like YouTube videos not playing on Safari and want to recover from a malware/adware attack.
- Open your Safari browser. Click on Safari and go to Preferences.
- Navigate to the Privacy tab and hit on the Manage Website Data button.
- Find and pick youtube.com from the list, then press the Remove button.
- Once done, restart your Safari and check YouTube.
Using a VPN app, whether free or not, can complicate things for you. VPNs allow you to surf the internet anonymously and securely. That is possible because they route your connection from their servers before seeing the content from the website to your computer screen. If the VPN's server is experiencing a technical failure, your connection would be even slower than usual. Thus, you cannot open YouTube, or it will result in Safari not playing YouTube videos.
Optimize Your Mac
In some cases, incorrect registry entries and system junk cause YouTube not loading Safari. This is why you should optimize your Mac regularly. You can optimize your Mac by downloading and installing a Mac repair tool. With a reliable tool, you can quickly get rid of unnecessary files and patch incorrect registry entries that are causing problems in your system.
- Make sure your Safari window is open and active. Navigate to the Safari menu in the upper left corner of your screen. Click on it and go to Preferences.
