I've read previous posts on this issue, including the replies to "You Tube not working ONLY in Safari", posted Feb 24th.

My macbook pro - Safari Version, 5.0.3 (5533.19.4, )- is working fine, but for some reason my iMac Safari, with same software and settings has decided not to play Adobe Flash Player.

I have uninstalled Flash player and reinstalled many times

I have deleted cookies as per Carolyn Samit's suggestion using renmoval tool at

I have emptied Safari cache several times

I have done a permissions repair

I have restarted the iMac many times

I have even tried loading an older version of flash player plugin

I have turned off the extensions tab in Safari preferences

I have unhid the develop Menu, and selected another User Agent with no success.

Still, evey time I load a page with flash content I get the message:

*Please install the latest version of the free Adobe Flash Player. Download now.*

*For help with Flash, see Adobe's Flash Player Support page.*

I've dowloaded the latest version of Flash player three times, but stiil no resolution.

*Any other suggestions would be gratefully received.*
iMac, Mac OS X (10.5.8), 2.4Ghz

    Which iMac?

    Try running Safari in 32 bit mode.

    you should start with Safari-Help-Installed Plug-Ins.... then see if Flash and other plugins are listed there - assuming that Safari-Preferences-Security-Enable Plug-Ins is checked On

    it goes to this blank page...

    ok, no plugins are working -

    Check firstly that the plugin files exist - paste this into safari's address bar & press enter
    /Library/Internet Plug-Ins/

    look in that folder - there should be several .plugin files, including Flash, usually.

    If that checks out - test Safari in a a New User Account & depending on the result, we'll know whether to look for a system-wide reason, or (perhaps more likely) something in your usual user account.

    If a new account behaves normally by showing a result in Safari-Help-Installed Plug-Ins,then switch back to the regular user, and start by quitting Safari & moving this file to the desktop

    then try it again.

    that's a shame eh - but to move forward, you'll have to reveal what you found in the plugins folder, and whether or not a new account showed any active plugins.
  • andyBall_uk Level 6 Level 6 (17,575 points)

    so you've done extensions, done the safari plist
    it works in a new account, so perhaps there's an account-specific add-on (beyond an extension) stopping all plugins from working.

    Anything in
    ~/Library/Internet Plug-Ins/ ?

    that's in your home folder

    ~/Library/InputManagers/ ?

    anything in System Preferences-Accounts-Login Items ?
  • andyBall_uk Level 6 Level 6 (17,575 points)

    there's the one in your account home... which is usually empty, duplicates here can cause problems.
    ~/Library/Internet Plug-Ins/

    and there's the one which is available to all users...
    /Library/Internet Plug-Ins/

    Copy/paste those paths to be sure which is which, if needs be.

    When I go to library/internet Plug Ins, they sometimes show, but usually show empty

    Um, that'd be a puzzle for sure - is that the home or main one? & what's in there when you can see things?

    Do I replace the file which you asked me to remove in an earlier post?

    it'd only be helpful if you had previously made a number of changes in Safari-Preferences... the file contains those settings & a few others, but a new, default one has already been created, so I'd leave it unless you've a pressing reason to replace the old.

    Just in case there's anything invisible in it, I'd trash the Home/Library/Internet Plug-Ins/ folder (the empty one)... it's a stretch to be sure, but better to exclude that possibility.

    Also, although they appear unrelated - remove the login items & logout/in. You can right-click on each beforehand to see exactly where they are in Finder.

    Also check in these folders which may exist in your Home/Library/

    it's empty by default, but files can be added which make apps or scripts run automatically.

    I forgot to ask (again) - did you add any software, or did anything else change, around the time that you noticed Flash had stopped working ?.
