YouTube white screen, black box in the corner

When on YouTube, on Safari, I go into fullscreen, and the screen is usually white, with a black box in the corner, and I have to end up refreshing. I am on a MacBook Pro Retina 2014 model. I have tried uninstalling my flash player, and reinstalling it, but it did nothing. I also tried to do the "run on 32-bit Safari" method, but I don't see the option to. Please help me!

MacBook Pro with Retina display, OS X Yosemite (10.10.5)

Turn all extensions off, relaunch Safari and test.

Turn those on one by one and test.

Man this is terrible i have the same problem. i suggest calling APPLE CARE and explain your problem, i just called a couple of hours ago and they told me that they didn't have any record of persons having the same problem .... That Is weird because i see a lot of people trying to solve this problem and even posting om youtube this problem and maybe if we all call and report this we'll maybe have a solution. You can search in google apple's care phone numer. Let me

know what the tell you! 😕

I did the same thing before posting the video on youtube. I talked with apple care and they connected to my macbook with screen sharing. I played multiple videos and that issue came with flickering black box in while screen while I was sharing my screen. I told them that issue is coming and they said yeah we can see that something is going on but we are not able to see which you are seeing currently at your end. That was really pathetic reply. I asked them what is the solution as I already had replaced my macbook three times due to that issue. I was on call with them for more than 3 hours and at last they told me that only option you have is to go to Apple store and talk with onsite engineers. It was really frustrating, how many times I need to go to apple store. Mine is new Macbook pro mid 2015 and somehow things are not going well in all the angles.

I feel terrible because i can't even ask for a new mbp because i'm currently living in Lima, Peru. And tell one thing man, are you having also problems with safari like crashes or anything unusual, because i for example am having some dificulties with loading some pages and all kinda weird unusual problems since i updated to yosemite 10.10.5 , the same for you?

I am not facing any safari crashed issue. After visiting so many forum I got to know that chrome is the better solution. With chrome i havent yet faced any full screen issue. By the way this was my first Mac book ever and seems like so many things are not smooth compare to Windows 10. I was hearing from long time that Mac OS has butter UI but seems like so many times while loading any effects it jerks. I didnt face anything like this in Windows while using just 4 GB ram laptop compare to 16 GB mbp. This is really weird. No doubt mbp would be far better but since 1 month I am using I havent feel anything very smooth which it supposed to be.

Hi all,


I am on mac book air (mid 2012), I face the same issue, the display goes weird when I am in full screen on YouTube, but also when I am on i-Tunes playing a movie. I don't seem to be able to resolve it. I have restarted my computer and it is fine for a moment and then again same issue. The apple guys are really not helpful (as usual!!).


Anyone any idea?


thanks

J.

Hey, guys! Sorry I haven't been posting on this thread with updates and such.


I found that this problem went away for me, after the OS X El Capitan update. I completely forgot about the problem, because it just went away.

I would recommend, if you haven't already, updating to the newest OS, and see if the problem is fixed for you. If not, then I've got no idea!

Thanks for your input Olivia, but you seem to be one of the lucky few. I am actually facing this problem since I updated to El Capitan. After "downgrading to El Capitan" I had issues connecting to To my Xerox printer, and it is certainly not thanks to the Apple support team that the issue was resolved. The same goes here, no one of the Apple guys seems to know how to assist or to even care. This is exasperating!

Hello,


As a temporary solution, I threw together a small app in Automator/Applescript which basically loads Youtube in a new window with iPad as the user agent (long story short: Youtube behaves like it would on a landscape oriented iPad, with resizable window). I also made a service so it is possible to right click on any Youtube URL in Safari and "Watch on Youtube Max" (dull name, I have no creativity left), and of course the standalone app works as well.


1. Run installer (provide password when asked, due to installing services).

2. Run app from your Applications folder or

3. Use the Services context menu when selecting a Youtube URL in Safari.


I was half asleep when I made this, and I have not had the chance to test it any further, use on own risk (although it should be perfectly safe - after all it only opens Safari browser windows, which is already installed on any Mac).


I hope this will be resolved soon anyway 🙂


Cheers,


Andreas
