Whenever I bring a video to fullscreen on YouTube (on Chrome or Safari), the video will go to fullscreen but the dock and menu bar remain visible, covering the top and bottom parts of the video. They used to be hidden when I went to fullscreen, so I don't know what happened. How do I fix this?

  • Go to the Apple menu, and from the Dock submenu select "Turn Hiding On". – Ruskes Jun 21 '14 at 17:58
  • I'd like the Dock to only hide when I'm in fullscreen mode though. Also that doesn't fix the menu bar issue. – Nicolas Trahan Jun 22 '14 at 18:40
  • Like I said, this used to be what happened before when going full screen, but it doesn't happen anymore. – Nicolas Trahan Jun 24 '14 at 19:11
  • I am seeing the same problem. – Ahmet Alp Balkan Aug 7 '14 at 4:52

    i saw similar behavior on archive.org. i believe it was the difference between flash and some other delivery method (html 5?). not sure how to test this immediately. – neuralstatic Sep 23 '14 at 15:44

If none of that works, open Terminal and enter killall Dock.

  • Good solution! Got a 1 up – Yariv Nissim Apr 6 '15 at 3:01

    This worked for me! But what did that do? – LampShade Sep 18 '16 at 3:25

    @LampShade: This force kills the process, like how you kill from Activity Monitor. Since, this is a crucial part of OS, iOS will restart it. Think of doing a reset to a good state(from buggy one). – saurabheights Dec 15 '16 at 16:34

I have this same problem with YouTube, Netflix, mPlayerX and VLC, where the Dock stays visible (on-top) after making the video go full screen.

This problem can be fixed by going into System Preferences...Mission Control and turning off the option "Displays have separate spaces." You have to logout after making this change.

Turn off displays have separate spaces

    This is wrong answer! What if I need separate spaces in my displays? – WebBrother Oct 7 '18 at 17:50

    You're missing the point....we all agree that it should work correctly and this should not be necessary. If you do this temporarily, it will work. Imagine my frustration when I first had this issue and had no solution at all...it just didn't work and there were no work-arounds. – flakshack Nov 2 '18 at 23:17

If you make the browser fullscreen before making the video fullscreen, this problem should disappear.

  • I made browser go fullscreen and then back to normal state. After doing this, dock disappeared when video goes fullscreen. Thanks! – rzaaeeff Feb 7 at 12:21

I had the same issue and I find it. This has to do with multiple monitors and mirroring (I connect my tv on the mac). Turn "Display mirroring" to off. That's it!


For me this works:

First switch Chrome window mode to full screen mode by pressing the green dot on the top left side of the view:

chrome full screen mode green dot

After that menu bar should be hidden so now enter full screen mode in youtube player:

youtube full screen mode

Enjoy your video on full screen without menu bar.


For me I had to use /Applications/Google\ Chrome.app/Contents/MacOS/Google\ Chrome --app="http://youtube.com" to have it work.
