Youtube Not Working Properly On Safari But Is Working On Chrome

Hello All,


I am having trouble running Youtube on Safari 11 on macOS 10.13 High Sierra (MacBook Pro Mid 2010). I just had the drive on my MacBook replaced 5 days ago so it is almost virtually true to the default factory settings. I have referenced other posts about Youtube not working properly on Safari and troubleshooted the problem using a few methods.


  1. Enabled Adobe Flash Player in Safari Preferences
  2. Enabled Javascript in Safari Preferences
  3. Empty Caches on Safari
  4. Deleted all Flash Player browsing data and settings
  5. Reinstalled Flash Player
  6. Restarted the Browser
  7. Repaired Disk Permissions with Disk Utility
  8. Restarted the Computer


This is how Youtube appears on Safari.

There is something peculiar, however, if I copy/paste a youtube link, I am still able to play videos.

I installed Chrome and Youtube works fine.

Thanks for your time and I look forward to any suggestions anyone has to solving this problem.

Have you considered upgrading Safari to Safari 12.1.2, which is the latest version? Check the App Store Updates tab.


Try setting up another admin user account in System Preferences/Users & Groups to see if the same problem continues. Please post back on whether or not this worked. Also try the Safe Mode. Please post back on whether or not this worked.

If it works in the Safe Mode, try running this program when booted normally and then copy and paste the output in a reply.
