Can't install Flash Player 12 via Safari on my Apple Macbook Pro 13" w/ 2.6 GHz Intel i5 processor. Error message says "User does not have sufficient privileges." I've worked w/ Apple Tech Support, tried various fixes, no change-it's not a setting on the Macbook. I've emailed Adobe requesting a fix. Any suggestions?
Adobe can't fix user permissions on your MacBook... and "User does not have sufficient privileges" comes from your OS, on your MacBook, NOT the installer.
Have you tried a "Clean Install"? (offline - NOT using Safari) How to perform a "clean install" of Flash Player in Mac OS X
or a COCOA install:
Right click the installer and choose "Show Package Contents"
Go to: Contents/Resources and double click the Adobe Flash Player.pkg file
