Thanks for the response and for the info. I've got Brick Daemon 2.2.2 installed and running (confirmed by the terminal output):
22510 0 com.tinkerforge.brickd
However, when I run Brick Viewer (version 2.2.7) the Brick IMU 2.0 is not listed, hence I cannot connect to it. The following error appears: "Could not connect. Please check host, port, and ensure Brick Daemon is running."
My settings: Host: localhost, Port: 2443 (Default, should it be changed?), and I can assure the IMU 2.0 is connected properly since it appears on Mac's system report.
Any further help would be much appreciated.
