Whenever I am closing the DM12 Editor Software on my MacBook (OS Yosemite), it is crashing and creating an error message. I tried connecting my DM12 via USB and Wifi but it keeps happening. Editor and Firmware are the latest. When I unplug USB or turn-off Wifi, the software is not crashing so it only seems to happen when the DM is connected. Anyone having the same issue and maybe having an idea to fix it?
