My iMac won't update adobe flash player?

It would have helped if you had said what version of OS X you are running.

Two bugs, one affecting Apple's Mac platform and another attacking Microsoft's Windows, exploit certain Flash player vulnerabilities to install malware onto users' systems, reports ArsTechnica. While users of other operating systems like Linux have yet to report attacks, Adobe's advisory notes the exploit affects all platforms.

Designated as CVE-2013-0634, the first vulnerability targets the Safari and Firefox Web browsers running on OS X, and is also being used as a trojan to deploy Microsoft Word documents containing malware. For Mac users, the flaw affects Adobe Flash Player version 11.5.502.146 or earlier.

On March 1 Apple again blocked Flash Player for Lion and Mountain Lion:

The Adobe Flash patch can be found on Adobe’s website, and users can visit this page to check if their software is the most curent version.

You should uninstall any previous version first, and repair permissions after installing the new version.

Before installing a new version of Flash Player you should first uninstall any previous version of Flash Player, using the uninstaller from here (make sure you use the correct one!):

and also that you follow the instructions closely, such as closing ALL applications first before installing. You must also carry out a permission repair after installing anything from Adobe.

I have the same problem...were you able to fix it?

You downloaded the one for Mac OS X, version 10.6 and later: uninstall_flash_player_osx.dmg (228 KB), quit all browsers, double-clicked the dmg file, launched the uninstaller app, and clicked the Uninstall button? What happens that leads you to believe it won't work? Are you sure that there's a Flash Player.plugin and a flashplayer.xpt file inside /Library/Internet Plug-Ins/? If not, then there's nothing to uninstall.

I was having the same probelm for over a week.. I uninstalled and installed numerous times.. finally I just deleted any Adobe flashplayer file that existed and now I can watch youtube videos! There is no Adobe flashplayer on my Macbook version 10.6.8 anymore and everything is finally working!

sorry.. it did work for a day..😕

to upgrade adobe flash with this issue. create a new user account, and install the flash from the new account. once it is installed, you can switched back to the original account and delete the new account. Flash will work without issues

good luck
