Thank-you however, I already have Internet Plug-ins enabled so that is NOT the problem. Preferences>Security>Interent plug-ins>All all other plug-ins, IS Checked.
And Safari and Flash were latest version and installed each several times uninstalled and re-installed many times, etc.
FLASH DOESN'T WORK WITH SAFARI anymore. So I no longer use much-broken Safari.
After many uninstalls and re-installs that just kept failing I stopped using Safari for awhile. THEN...
I manually removed the Flash Plug-in and any older backups from my Internet Plug-ins folder, re-booted my computer (yes to compeltely clear it), installed Flash, then rebooted computer (again) and I got Flash to work better in Safari.
Other browsers work better though and have less issues working on more webstites.
GUYS I HAVE DONE IT!!!!!
I tried repeatedly installing it, restarting my iMac and installing Google Chrome (instead that said that browser was open too when it wasn't).
And finally...DUN DUN DUN...I have found the solution!
The iMac equivalent to Task Manager is Activity Monitor.
So, go to your launchpad, search it up and then when you are in Activity Monitor, simply click on Safari and click the X icon in the top left hand corner, below the actual X button to close the window.
You're welcome in advance ;-)
That did it! OMG thank you. Ive been trying to chase that down for.... years? Yosemite didn't fix it etc...
Turned out it was my preferences in Safari (Just like smsgatorsaid)
> Choose Safari
> Check "Enable Plug-Ins"
I didn't have to re install
