Are you getting a blank or black screen when trying to play YouTube videos or flash content on Mac OS X? When searching for an online solution, I found a few troubleshooting steps, but no solution seemed to correct the errors of the blank video player. However, by doing a little troubleshooting of additional problems, I found an alternative solution, which uses some basic troubleshooting steps.

The problem with video or flash games that do not work in browsers such as Safari, Firefox or Google Chrome on Mac OS X is mainly due to a combination of configurations and compatibility issues with Adobe Flash Player, the software that allows you to play these videos based On the web With the following steps for troubleshooting, you should be able to get videos and flash games on a Mac computer.

Keep in mind that YouTube really does not use flash anymore, so nobody should have this problem anymore. However, there are many other sites that still depend on flash, so the steps below can help solve problems on those sites.

1. Uninstall and reinstall Adobe Flash Player (be sure to install the latest version)

This may solve the problem of the flash video and it may not, but it is worth trying. Start by going to the official Adobe website and downloading the Flash Player uninstaller for OS X. Start the uninstaller and simply uninstall Flash Player from your Mac and restart the computer.

Once your computer restarts and you have logged in, proceed to Adobe.com to download the latest version of Flash Player. Reinstall and check if the YouTube videos are working.

2. Enable Flash in Chrome/Safari

In Chrome, click on the three points at the top right and click on Settings. Scroll down and click on Advanced to expand it. In Privacy and Security, click on Content Settings.

Scroll down to Flash and then turn on the control to say Ask first (recommended).

If you have already installed Flash for Safari, but it still does not work, you may need to enable the add-on first. To do this, open Safari and then click on Safari at the top and click on Preferences.

Click on the Websites tab and there should be a section called Add-ons at the bottom of the left panel. Make sure Adobe Flash Player is marked. If it does not appear in the list, be sure to go to the Adobe Flash website and download the latest version of Flash first.

By default, you will have to enable it site by site. You can see the list of sites for which it is enabled and, at the bottom, you can choose whether Flash will be enabled or disabled for all other websites.

3. Reset Safari, Firefox, Chrome, and Clear Cache

If Flash Player still does not work properly, you can try to clear your browser’s cache, exit the browser and restart. Some people have reported that the videos will work correctly when clearing the cache.

In Chrome, you can click on the three points, then click on More tools and choose Clear browsing data. Be sure to check the images and files in the cache and then click the Clear data button.

4. Enable Javascript and Disable Popup Blocker

A lot of Flash content requires Javascript, so if you have an extension that is blocking Javascript execution, you should disable it. You must also access the browser settings and make sure that Javascript is enabled.

You can also try disabling the pop-up blocker for the particular site where you have problems. It is not a good idea to turn off the pop-up blocker completely, as it will make your computer less secure.

5. Disable Flash hardware acceleration.

While on the blank YouTube video screen that is not working properly, right-click the area where the video will normally be displayed to open the Flash Player context menu. Select the option Configuration in the menu. Uncheck the Enable Hardware Acceleration option and click on the Close button.

If you do not see the right-click context menu, simply visit this Adobe help page and right-click on the Flash logo. If you do not see the Flash logo, it means that Flash is not installed correctly.

Close the browser completely, restart and try the Flash content again to see if it is playing.

6. Check HTML 5 YouTube Settings

YouTube now supports HTML 5 completely and whenever you are running a fairly recent version of your browser, all functions must also be fully compatible.

If you go to this URL, https://www.youtube.com/html5, you should see check marks for all the different HTML 5 features. If something is not checked here, that means that your browser is very old and needs to be updated.

Hopefully, this publication will help you solve problems with blank video players and Flash applications that do not work on OS X. If you have other recommendations for troubleshooting, do not hesitate to leave a comment. Enjoy!
