I just got in last night from a United flight. During the flight, I installed (against my better judgment) their in-flight DRM plugin so I could watch a movie on my MacBook Pro.
The playback was terrible on my laptop anyway, so I switched to the United app on my iPhone which was surprisingly decent.
But now, how do I get rid of the DRM plugin?
Googling around revealed absolutely nothing. United, of course, doesn't say anything in their FAQ about where this plugin is installed.
I finally did a Finder search and found a file named
/Library/Internet Plugins. I deleted that file, and after more Finder searches couldn't find anything else.
So, for a one-liner you can put into Terminal:
sudo rm /Library/Internet\ Plugins/PanasonicDrmPlugin_2.plugin
Hope this helps someone else!
