YouTube black screen on a Mac...

SOLVED, SOLVED

first i have deleted all the coockies, as you suggested, and the stuff from flash player in settings, did not work.

UNINSTALLED Flash + Repair disk permisions + Restart i should have installed flash ** did not, and every thing WORKS

No Way I would use Safari in 32bit mode! Why? Just because of the Adobe dilettanteism?!

This is also in Firefox

Actually I was in a way, wrong!

I did have to install Flash player again fot the youtube controls to work and the problem reappeared on some embedded youtube videos - just on some!

Later friday evening gmt+02, miracle happened: No problems what so ever!

Everything works OK!

no need! Mine works in 64 bit... read, please, my latest reply.

Sorry but I dont think so. This was one of the first things I did after I have figured out that Flash causes this Error. Disk permission repair I did way before, this one of the first things to check if anything dont work properly.

With the newest Flash Player it did not accurre with my first Youtube Test Video that produces this Error always before. So I thought first this does the fix. But a Day later it occurs again, with other Youtube Material and/or without embedet Video but other Flash content. Now I do the test with the 32 bit Mode. And since now it seems only this does the trick.

Mcpro-User:

uninstall flash, reboot. repair disk permission if you will, than test youtube - play pause should not work properly. reinstall (using your browser suggestion, in flash suggestion... whatever) , reboot.

mine works!

Friday I spent 2h to make it work. tried safari 32 bit mode, did not work. after a successful uninstall with reboot and a reinstall worked just for the first embedded video than stopped working, but just on some posted on an worldpress based website, others like the ones on innerfidelity.com where ok. on youtube things were just fine. later during the evening coming from the pub I was amazed to see that it works flawless.

here is again the link to the uninstaller:

No Problem I am in Test Mode. I will try now 64 bit Mode with a clean Adobe install. After a Day running this I will give Feedback if this works also on my Setup.

I have checked this out. I dont work for me. Uninstall before install dont help. Rund this half a hour and the Screens turn black. It is like with the latest Adobe Install before. And I think in my case this Problem comes exact with this newest Adobe Install. I have had not Problems before. The only Solution that seems to work is setting the Browser to 32 bit Mode.

Globaly an immense damage this Adobe Problem. What I've read here, some People returned Computer and exchanged whole motherboards.

I am so sorry that it did not work for you! 😟

for youtube issues at least mght work

Or . . . you could switch to Firefox which thus far does not seem to have these issues.

Problem is still there, and it is Hardware related. I found some Articel about this:

http://www.cnet.com/news/os-x-lion-black-screen-bug-likely-from-hardware-malfunc tion/

So my conclusion is now it is Apple and Lion who cause it. In my case it is the old Graphics Card. But my old Mac pro is now worth half as a new graphics card. Seems a typical case of changes of the software running old hardware unusable.

But time is right. Apple has won I buy a new Mac Pro. But it has a bad taste.
