Clear Browser Cache

Every browser saves data on its local storage. The browser saves your settings whenever you visit a website and puts them in a temporary cache container.

The cache memory enhances your experience whenever you revisit a website.

Now, many websites have content that takes time to load. So when the cache is almost complete, you might not see that heavy content, especially videos.

Therefore, you must clear the browser’s cache to watch videos without trouble.

Check Browser Extensions

We install different extensions to enhance the functionality of the web browsers. Some of the standard browser extensions are:

  • Ghostery Lite
  • StopTheMadness
  • PiPifier

The above extensions allow you to get the most out of web browsers. As a result, you can browse the internet freely as you get anonymity instead of exposing your identity. Moreover, hard-to-use websites become more user-friendly using such extensions.

Install Adobe Flash Player

Since the recent advancement in web development, most websites have moved to HTML 5 with new internet technologies. As a result, these websites no longer use Adobe Flash Player.

Therefore, if you visit an old website where playing videos is not allowed, you must re-install Flash Player.

Now, try the following method to fix YouTube videos if the problem is still there.

Scan Your Mac

Many Mac users complained that while watching YouTube videos, the computer crashed. Sometimes the browser becomes unresponsive. Sometimes the whole Mac system freezes.

Moreover, online videos don’t play on almost any website.

If you have applied all the fixes but still get the same error while playing a video or video playback, the issue might be with the operating system.

Therefore, you must scan your Mac system and check whether it’s affected by malware.

Why Scan Your Mac

When an intruder attacks your Mac, it tries to get into the user’s personal information. In addition, the intrusion attempts to corrupt the primary Mac OS files that run basic functionalities like playing YouTube videos and other online media.

So, scan your Mac for possible intrusion. If the system diagnoses any suspicious files, quickly get rid of them. Then, restart your Mac and play a YouTube video to test the performance.

Unblock Ad Blocker

Another thing you can try is to disable ad blockers on a website that is not playing videos. No doubt, an ad blocker is proper through which blocking unnecessary content becomes accessible.

However, you must check if the content blockers intentionally block the videos on a website.

You can do that by opening the extensions you installed on the Safari browser. First, Safari loads the content on the websites, but the ad blockers block the online videos.

So, if that’s the ad blocker that was stopping you from playing videos, disable it.

Check Internet Connection

One last fix is to test whether your internet connection is stable to play online videos. You can run a speed test from different platforms that give:

  • Ping
  • Upload Speed
  • Download

The download speed is the key factor that determines how good your internet connection is. Therefore, check the speed of your network.

If it’s slower than your subscription plan, contact your internet service provider (ISP). They’ll tell you the issue with the internet connection.
