I have successfully paired Mac with Lego Mindstorm EV3, and the connection is stable. However, the command

myLego = legoev3('Bluetooth','/dev/tty.EV3-SerialPort');

brought the error message

Error using error
Unable to load a message catalog 'legoev3io:build'. Please check the file
location and format.
Error in legoev3 (line 157)
error(message('legoev3io:build:CommInvalidType'));

I have spent hours but could not find a solution. I also tried

legoev3('USB')

but it gave the some error message.

On the other hand, I can send commend from Lego Mindstorm EV3 software either from USB or Bluetooth without any problem.

Please help!

Many thanks Kyle

The most common cause for being unable to load a message catalog is that there has been a loop that leaked open files and so there are no available open file handles to open the file. That is the most common cause. But sometimes the message catalog simply is not there for some reason.
