Part 1. Why is My Video Not Playing on Mac?

Before heading to the solutions, it's essential to find out why videos are not playing on Mac to avoid facing this issue in the future. In most cases, any of the below reasons can make your videos unplayable on a Mac:

1. Browser Issues

One of the major causes of any online videos not playing on Mac is issues in your browser. It can be anything from the browser not being compatible with the video resolution or platform to bugs in the cache.

Users should try to update the browser and clear cache and history to get rid of browser-related problems. At times, just a simple refresh fixes the video error. Also, try to play the same video on another browser to check if your browser has a compatibility issue.

2. Internet Problems

Streaming online videos require an active internet connection. Unfortunately, your internet may be disconnected or too weak for you to play an online clip, leading to videos not playing on Mac.

3. System Issues

Sometimes, a temporary glitch in your Mac can disrupt the normal working of your browser, and it cannot play videos. A simple restart can often help you get rid of system issues and play the video smoothly.

Part 2. Common Ways to Fix Videos Not Playing on Mac

Below are the proven five solutions to fix why videos not playing on Mac. Implement them one by one until your videos run smoothly.

1. Check the Internet Connection

The first thing you should do is check if you have an active internet connection or not. Then, try to refresh the web page or load another page to see if the internet is working. If not, switch off the router and turn it on again after a few seconds. If the internet is still not working, call your internet provider and have the issue resolved.

2. Enable JavaScript in Browser

If you don’t know already, JavaScript is the official programming language of interaction between your web browsers. Sometimes, users inadvertently disable JavaScript on the browser, which causes many issues, including videos not playing on Mac, video stuttering or not loading at an average speed, and other video playback errors.

Follow the below steps to enable JavaScript on the browser:

Step 1. First of all, launch the Safari browser on your Mac.

Step 2. Now, click on the "Preferences" option and select "Security".

Step 3. Here, check the "Enable JavaScript" box if it's not already.

Click on the "Add" button (shown below) and choose the damaged video to fix its MKV no sound problem. Interestingly, you can drag and drop your file on the main interface.

3. Check Safari Extensions

Many of us have installed the third-party extension on our web browsers to boost efficiency. However, any official or third-party extension may stop a video from playing in some cases. It may sound like an implausible scenario, but it does happen to many users.

Here’s how to disable some of the extensions on your browser:

Step 1. First, open the Safari browser and hit Preferences in the menu bar.

Step 2. Then, open Extensions and disable all the extensions.

Step 3. Finally, close the browser and relaunch it. Now, try to play the video and check if the issue persists.

If the video starts playing, it indicates that any extension was the culprit. So now, start enabling the extensions one-by-one while you keep playing the video. This way, you will get to know which Extension you should delete from the browser.

4. Convert Videos to Supported Formats

Another common reason for videos not playing on Mac is compatibility issues. The browser or your media player does not support the video. The easiest way to overcome this problem is by playing the video on another browser such as Chrome, Firefox, Safari, etc.

If you're trying to play a downloaded video, but it is of no use, consider using a competent video converter to change the video format to a compatible format. Some most popular video formats for Mac are MOV, MP4, M4V. You'll quickly get your hands on an efficient converter to change the video format to any of these formats.

5. Clear Cache

If you haven’t deleted the browser cache and cookies for quite some time, then do it now. Sometimes, the accumulated cache slows down the working of a browser, leading to videos not playing on Mac.

Here’s how to clear cache on your Mac:

Step 1. First, run the Safari browser and go to Preferences.

Step 2. Then, hit "Advanced" on the top bar and check the box that reads, "Show Develop menu in the menu bar".

Step 3. After that, click on the ‘Develop’ menu and choose "Empty Caches".

Step 4. Next, restart the browser and play your video again. Hopefully, it will stream smoothly.
