Overbridge: restarting my laptop?

Hey guys! New Electron user since yesterday here! Still learning my analog keys but it seems like every time I start the overbridge mode on my AK, it restarts my macbook (El capitan)
It actually doesn’t reboot if I launch the Overbridge Control panel before setting up my AK in Overbridge Mode. But it’s still confusing because I’ve just closed my macbook to take a break and when I came back it restarted. What am I doing wrong ? Thanks!
