Updated Flash, Now Safari 9 Wont Play Many Videos

Same problem. Safari nor Chrome would start videos on Youtube or Facebook. I uninstalled Flash. No difference. Then uninstalled Java. Bingo. Videos play in Safari better than they ever have. Chrome plays them fine. I think a Java update caused my problem a week ago so for now, it's gonna be life without Flash and Java.

1. Uninstall Adobe Flash Player:

Make sure that step 2.9 is not skipped.

2. Reinstall Adobe Flash Player.

3. Allow Plug-ins

Safari > Preferences > Security

Internet Plug-ins > "Allow plug-ins"

Enable it.

The solution did not work for me. Any other ideas? Thanks in advance and NO thank you, Apple.

Try Safari/Preferences/General and set Show scroll bars to when scrolling.

Thanks, Eric. Before I could try your suggestion, it started working again. Go figure.

Best,

Tom

I am having this problem too. I can hear the audio but there is no video. I have done everything in this discussion and more.

Problem with all browsers except Chrome but the screen flashes in Chrome so it is not usable.

I removed and reinstalled flash.

I have erased and installed IOS from scratch

Any other suggestions are welcomed.

I have the following setup:

Model Identifier:
MacBookPro9,2

Processor Name:
Intel Core i5

Processor Speed:
2.5 GHz

Number of Processors:
1

Total Number of Cores:
2

L2 Cache (per Core):
256 KB

L3 Cache:
3 MB

Memory:
4 GB

Boot ROM Version:
MBP91.00D3.B0D

SMC Version (system):
2.2f44

IOS X El Capitan 10.11.16

Safari 9.1.2

Try a restart.

Do a backup, using either Time Machine or a cloning program, to ensure files/data can be recovered. Two backups are better than one.

Try setting up another admin user account to see if the same problem continues. If Back-to-My Mac is selected in System Preferences, the Guest account will not work. The intent is to see if it is specific to one account or a system wide problem. This account can be deleted later.

Isolating an issue by using another user account

If the problem is still there, try booting into the Safe Mode using your normal account. Disconnect all peripherals except those needed for the test. Shut down the computer and then power it back up after waiting 10 seconds. Immediately after hearing the startup chime, hold down the shift key and continue to hold it until the gray Apple icon and a progress bar appear. The boot up is significantly slower than normal. This will reset some caches, forces a directory check, and disables all startup and login items, among other things. When you reboot normally, the initial reboot may be slower than normal. If the system operates normally, there may be 3rd party applications which are causing a problem. Try deleting/disabling the third party applications after a restart by using the application un-installer. For each disable/delete, you will need to restart if you don't do them all at once.

Safe Mode - About El Capitan

Safe Mode Startup – El Capitan.

I did safe mode and the problem was still there. I created another account and it was still there. The HDD was erased and reloaded with the OS two days ago. I have a case opened with Apple and I am not at level two support. So far we have gone through all of the usual recommendations to fix the problem and it is still not working. If Apple fixes it then I will post the fix here. Thanks!

I FINALLY found the fix on my own. This is what worked for me.

Go to a window that is showing audio and no video.

Do a "control/click" or doubletap in the video window.

Select Settings

Uncheck "Enable hardware acceleration.

Close the window.

At this point I was seeing video in the Flash Player.

I just disabled Adblock for the page I want to see the video. All good!
