I just updated to Mavericks, and Flash no longer works on Safari. I uninstalled everything and reinstalled flash. The error said that this version of Flash was missing security updates so it was blocked. I went to System Preferences and checked for an update, but none was found.
I downloaded and installed Firefox, and flash works perfectly.
Does anyone know what the issue is?
Thanks.
MacBook Pro, OS X Mavericks (10.9.1)
Open System Preferences > Flash Player then select the Advanced tab.
Click Delete All under Browsing Data and Settings
Now empty the Safari cache. From the Safari menu bar click Safari > Preferences then select the Advanced tab.
Select: Show Develop menu in menu bar
Back to the Safari menu bar, click Develop > Empty Caches
Quit and relaunch Safari. try a Flash based video.
If you're sure you've installed the latest version of Flash, take each of the following steps that you haven't already tried. After each step, relaunch Safari and test. In rare cases, you might have to log out or reboot to force a Flash update to be recognized. For a "missing plug-in" error, start with Step 5.
Step 1
If you're only having trouble with YouTube videos, sign in to your YouTube account and load this page. You may see a link with the text "Leave the HTML5 Trial." If so, click that link.
Step 2
If you're getting a "blocked plug-in" error, then from the menu bar select
▹ System Preferences… ▹ Flash Player ▹ Advanced
and click Check Now. Quit and relaunch your browser.
Step 3
Triple-click anywhere in the line below on this page to select it:
/Library/Internet Plug-Ins
Services ▹ Open
from the contextual menu.* A folder should open. Delete the following item, or anything with a similar name, if present:
Flash Player (failing).plugin
You may be prompted for your login password.
*If you don't see the contextual menu item, copy the selected text to the Clipboard by pressing the key combinationcommand-C. In the Finder, select
Go ▹ Go to Folder...
from the menu bar, paste into the box that opens (command-V). You won't see what you pasted because a line break is included. Press return.
Safari ▹ Preferences... ▹ Security
from the Safari menu bar and check the box marked
Allow (or Enable) plug-ins
Then click the button marked
Manage Website Settings...
if present and make sure that the website is not blocked for Flash.
Step 6
Select
Safari ▹ Preferences... ▹ Extensions
from the Safari menu bar. If any extensions are installed, disable them.
Step 7
In the Safari preference window, select
Privacy ▹ Remove All Website Data
Close the window. Then select
▹ System Preferences… ▹ Flash Player ▹ Advanced
and click Delete All. Close the preference pane.
My problem is that it's only the latest version of Flash Player that causes this problem for me. Everything worked fine with Flash 11, but since upgrading to Flash 12, it doesn't work in Safari (7.0.1) anymore. None of the steps described above accomplished anything.
Flash 12 works fine in Firefox (26.0) though.
I'm in the same boat. Youtube not playing in Latest Safari with Latest Mavericks.
However, everything works using Firefox.
Step 2 worked for me.
Worked like a charm… thanks Linc Davis!
Flash 12 does not work with Safari?
