Youtube not working properly on Safari 5?

Same problem. Started the 16th Feb. Has only affected my MacBook (mid 2007 model). Running Safari 5.0.3 on Mac OS X 10.6.6.

Temporary solution was to run Safari in 32-bit mode.

Fear Not! After much angst trying all the "troubleshoots" with Youtube and Flash, I followed the advice here. I just switched to 32-bit on Safari and it worked. Thanks fellow Apple Users

Hi All,
A big thanks for the 32 solution, worked well for me! Still not sure what the affect of operating in 32 bit mode is..... or if this is a Apple problem that will be resolved?

Running in 32 bit mode means Safari will not manage memory as efficiently as 64 bit mode. Not really that much to worry about though, as Safari is admittedly a bit of a memory hog already in 64 bit.

This problem seems to relate more to Youtube/Adobe with java. So they will be the ones to fix the problem, not Apple.

Another tip to fix that: change the User Agent.

Safari - Preferences - Advanced - Enable Developer

In Developer menu item: User Agent - Select any different from the "automatic" or "Safari 5 - Mac". With any other seems to work.

To fix it forever, just type this in the Terminal:

defaults write com.apple.Safari CustomUserAgent "\"Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10 56; es-es) AppleWebKit/534.21+ (KHTML, like Gecko) Version/5.0.3 Safari/533.19.4\""

I've only changed Mac OS X 10.6.6 to 10.5.6 and it works fine. All 10.6 seems to fail for me. Where it says "es-es" just put your language and country, as an example for english in England: en-uk

What I don't understand is why my wife has this problem on her macbook (which is fixed by switching to 32bit) but I don't on my mac pro. Both running 10.6.6 and both with exactly the same version of Safari. I tried the latest beta version of flash player for 64bit (they call it 'square') in her macbook but that wasn't a fix.

Switching to HTML5 worked for me too, but only when I'm logged into an account that's opted in. This needs to be properly sorted ASAP.

Open up safari in 32 bit mode and it will fix it.
Instructions.
Open Finder
Applications
Right Click Safari icon
Click Get Info
Click on open in 32bit mode
Close
Restart Safari and it should work.
I just had this problem and it fixed it instantly.

I have tried all of the solutions listed on this discussion board and nothing works for me

MAC OS X 10.6.6
Safari 5.0.3

I tried switching to 32-bit mode & its still not working! So in the meantime YouTube is totally bunk for me. (MacBook4,1 running Safari 5.0.3 & OS 10.6.6)

I noticed the same thing yesterday.
No issue with youtube via Firefox but unable to load directly through Safari.

The only fix I found as mentioned before was to enter via the youtube username and locate the video from there.

I wonder if this has anything to do with having or not having a discreet graphics card.

No it doesn't. I have the same problem w/o a discrete gpu.

This problem is ridiculous and the solution is terrible. No way I'm switching back to 32-bit mode just because Youtube screwed something up server-side.

Youtube needs to fix this asap. Until then I'll continue to use the play via the user's channel workaround. Just the fact that you can play all videos in the channel but not on the main page shows this is a Youtube and not a Safari issue.

Youtube's advice is 32 bit mode and/or disable hardware acceleration while they figure it out:

and here

If someone actually checked the source of the pages which show black, or at least right-clicked on the black & said whether or not Flash is being written to the page... then do tell youtube, since they may fix it sooner.

FYI...

The issue with youtube videos not playing began directly after I attempted to post a facebook link in a video comment box. Now when I reset safari (http.....tvneto.com..... and http....game-gt.com.... and something that says facebook embedded) will not reset off my history screen.

hopefully a clean install won't be required.... there is nothing in my Finder-Library-Internet Plug Ins folder to delete
