So a user of mine was cleaning up their Documents folder on their MAC. Later that day they tried to open 3cx For Mac and it would not register. It seems they deleted a folder that 3cx uses to store logon info and other preferences. Just wondering why this is not in Users/username/Library/Preferences. Or /Users/username/Library/Application Support ? Perhaps this is an oversight – or something 3cx has done on purpose – but it has caused some headaches recently.
