Hello,
From my understanding, you are receiving an "Cannot detect arduino hardware" error when trying to connect an arduino in MATLAB on Macbook while using the "arduino()" command.
Without specifying parameters to the "arduino" command, MATLAB seems to be having trouble detecting Arduino devices on your machine.
Please try connecting to the Arduino board by explicitly specifying the port ID and board type in the "arduino" call. On a Mac the port string often starts with "/dev/". As an example:
>> a = arduino('/dev/tty.usbmodem1421','Uno')
a =
arduino with properties:
Port: 'COM3'
Board: 'Uno'
AvailablePins: {'D2-D13', 'A0-A5'}
Libraries: {'I2C'}
There could be several reasons you are experiencing the issues. You can try the following troubleshooting steps mentioned in the MathWorks documentation.

It worked! Just go on arduino check the port name, then use same name.
To connect type:
a = arduino('/dev/cu.usbserial-1110', 'uno');
%the underline is the name of my port so its just an example. You will have to find out what yours is called.

This sometimes happens when you connect the arduino through a hub instead of directly to the USB port.
Possibly this would not happen if you were to connect the arduino to a Thunderbolt dock.
