I'm pleased to announce that Flash Player 18.104.22.168 for Mac is now available from http://get.adobe.com/flashplayer. This release resolves the crash described in this thread. As noted below, you can either download this immediately from adobe.com or wait for the update to be applied automatically, within 24 hours, via our recommended auto update mechanism. If you encounter any problems updating, please visit http://helpx.adobe.com/flash-player.html for basic troubleshooting steps.
We are aware that Macs created between 2006 and 2008 are currently running into problems using the latest release of Flash Player (version 13). We apologize for the inconvenience that this is causing. We are actively investigating the cause and hope to have a full solution to you shortly. In the meantime, please follow this two step procedure which will revert you back to version 12.
- Download and run our uninstaller:
- Download and run the version 12 installer from*:
After installing Flash Player, you might be presented again with our update dialog. You have a couple of choices to deal with this.
I recommend simply clicking the red close button on the dialog's title bar to dismiss the dialog. This dialog will show up once every 7 days or until we update you silently and automatically with the fixed version (45 days maximum).
The other option is to change the notification option during the install to "Never check for updates (not recommended)." This will suppress the dialog completely. At some point in the near future Safari will block the old version of Flash Player and you'll be prompted to reinstall the new version of Flash (with the fix). When that happens you can return to the automatic update selection.
I will continue to update this thread and post to twitter (@liquidate) when new information is available.
We have determined that this problem is due to a compiler update in our build infrastructure that exposed a long-standing bug in a Mac system library. Flash Player now attempts to use CPU instructions that are not available on a subset of supported Mac hardware from 2006 to 2007. None of the machines in our compatibility labs are affected, so the issue didn't show up in our testing, but we were able to track down a machine that reproduces the issue yesterday. We're actively working on a fix and I'll update this post again once we have more information.
Our developers have found a fix for this issue and our quality assurance team will be testing this new build out over the weekend. If everything looks good, we'll work on how and when we'll get this deployed.
Testing over the weekend went well and no new issues were found. We're now working with our deployment teams to get this out to all Mac users. If the testing and web staging go as planned, we expect that we'll have this update available for download on Wednesday, April 16th. If you have the Flash Player update mechanism (found in the Advanced tab of the Flash Player system preference panel) set to "Allow Adobe to install updates (recommended)" then you will receive the update within 24 hours of the release being made available. Customers that have the option set to "Notify me to install updates" will get a notification dialog within 7 days. We will also make this update available for download though http://get.adobe.com/flashplayer. I'll post again if we run into any snags or when the update is made available.
