Loading Security and Privacy System Preference stuck
Clicking "Security & Privacy" does NOT take me to setting window. Instead all I see in title bar is "Loading Security & Privacy . . .".
Don't know if this is related but I download an update from EASTWEST Sounds for their PLAY engine, and I got an error indicating I could not open the install package because it was not signed or downloaded from the App store.
Then I clicked Security & Privacy and nothing happened.
I rebooted, still same problem.
I found a workaround on the Internet to get the software installed, however I still have a stuck "Loading Security & Privacy ..." title bar.
Workaround was to type in Terminal:
sudo spctl --master-disable
