LogMeIn has identified the cause of this issue, and stated it may be caused by Fast User Switching.
While LogMeIn works on the fix for this issue, I have found a workaround.
The solution is to disable Fast User Switching entirely. While this may be an issue for some users that bounce from one account to another, this will [seemingly] fix the issue with LMI.
To permanently disable FUS on a Mac machine, run these Terminal commands:
- sudo defaults write /Library/Preferences/.GlobalPreferences MultipleSessionEnabled -bool false
- defaults write .GlobalPreferences userMenuExtraStyle -int 0
- defaults -currentHost write com.apple.controlcenter UserSwitcher -int 8
So far, every machine we have deployed this fix on has not had the issue again - even after multiple restarts and attempts to break LMI again.
