I'm not sure how this machine was setup, but I do have control over it now as a local admin.
I need to enable fast user switching, but the option is greyed out along with some others. This is after unlocking the changes padlock.
Is there anything I can do to reenable these options?
sudo defaults write /Library/Preferences/.GlobalPreferences MultipleSessionEnabled -bool NO
. Perhaps try that with-bool YES
? Oh: also, here is a similar question with no answers.
