Scroll down to Flash and then turn on the remote to select Ask First (recommended).

If you have already installed Flash for Safari, but it still does not work, you must first enable the plugin. Open Safari and then click Option. At the Websites tab, there will be a section called Plug-ins at the bottom of the left panel. If Adobe Flash Player is not listed there, visit the Adobe Flash website and download the latest version. You can then choose whether Flash is enabled or disabled for all other websites.

Check the Plugin.

3. Reset Safari, Firefox, Chrome and clear the cache

If Flash Player still doesn’t work properly, you can try clearing your browser’s cache, leaving the browser, and restarting. Some users shared that they were able to watch normal YouTube videos on the Macbook after clearing the cache.

In Chrome, you can click the three dots, then click More Tools and select Clear browsing data then click the Delete data.

4. Enable Javascript and disable Popup blocker

A lot of Flash content requires Javascript, so if you have an extension that is blocking JavaScript from running, you need to disable it. Also check the browser settings and make sure Javascript is enabled.

You can also try disabling popup blockers for the specific website you’re having trouble with.

5. Disable Flash hardware acceleration.

On the screen of the YouTube video not working correctly, right-click on the area where the video is usually displayed to see the Flash Player menu. Choose an option Install from the menu, uncheck the option Enable hardware acceleration and click the button Closed.

If you don’t see the content menu, you can go to the Adobe help page and right-click on the Flash logo. If you still do not see the Flash icon, that means your Flash is not installed correctly. Please close your browser, relaunch and check Flash content to see if it plays.

6. Check YouTube HTML 5 settings

Check Youtube 5 HTML settings.

Currently, YouTube supports HTML 5 for recent browser versions. If you visit the URL https://www.youtube.com/html5, you will see a highlight for all features HTML5 different. If nothing is checked there, your browser is very old and needs updating.
