7 Best Fixes for YouTube Videos Not Playing on Mac

YouTube has become the hub for finding and watching videos of almost every genre. You can enjoy your favorite content by selecting the video quality on YouTube. But what if none of your Mac’s browsers can play YouTube videos?

Are you currently facing this problem and getting restricted from enjoying YouTube content? If yes, this post will show you the best ways to fix YouTube videos not playing on Mac.

1. Check Your Internet Connection

We recommend checking the strength and consistency of your internet connection. If you have a dual-band Wi-Fi router at your disposal, connect Mac to a 5GHz frequency band and run a speed test. This will help you check whether your Internet Service Provider is facing any downtime or throttling the speeds.

2. Reduce Video Playback Quality

YouTube can stream videos at up to 8K resolution if your device supports it. But for those with limited bandwidth and data, changing the video playback quality is a good option if YouTube videos are not playing on your Mac. Check which resolution works best for you.

3. Check HTML 5 Support

Some videos on YouTube require HTML 5 support instead of Adobe Flash Player for smooth playback. So you’ll need to check if your web browser supports HTML 5. Head to the YouTube’s HTML5 video player page and enable the same for your browser. The same page will show whether your browser supports HTML5.

4. Force Quit and Relaunch Your Browser

Another solution is to force quit and relaunch the web browser on your Mac. If your browser has been running in the background for a long time, you’ll need to force quit and give it a fresh start. The following steps remain the same no matter which browser you use on your Mac.

Step 1: Click the Apple icon in the top-left corner.

Step 2: Select Force Quit from the list of options.

Step 3: Select your browser from the list of apps.

Step 4: Click on Force Quit.
