What is "join.me helper tool" for Mac?
When Mac users install the join.me desktop application for the first time, they are asked to enter an administrator's name and password, as illustrated.
This allows installation of a small app we call the join.me helper tool. The join.me helper tool allows the join.me desktop application to silently update itself automatically without forcing you to enter an administrator's name and password each time.
Once you have the helper, join.me is able to update itself without your interaction.
