So I read on the Multiclienting thread that all you have to do on Mac is download the client a second time to multiclient. I tried this. Downloaded, installed, double clicked on MapleSaga icon... it requests permission to open, I click allow/approve/whatever, and nothing happens. What am I doing wrong?
Okay, you are a life saver! Apparently downloading and unzipping a second copy and trying to install and open that does NOT work. But duplicating the same .app file DOES work. Such a simple solution. Thank you!
