Terminal is the easiest way for me (I'm an old Unix guy though). Here's the best I can do for a step-by-step:
- Open the Terminal
- Change to the extensions library: cd /Library/Extensions
- Run the following command (you will be prompted for your login password*):
sudo find /System/Library/Extensions/ /Library/Extensions/ -name osx-pl2303.kext -o -name osx-ch341.kext -o -name usb.kext -o -name ProlificUsbSerial.kext -o -name ch34xsigned.kext
This will show whether you have any conflicting serial drivers.
After installing the WinChipAhead driver, you should only see usbserial.kext in the /Library/Extensions directory. If you see anything like ProlificUsbSerial.kext or something else with USB in the name, I would suggest that you move them to a temporary folder in your home directory. A reboot should ensure that the correct driver is loaded on your system.
From there you should be able to connect the mBot with the USB cable, turn on the mBot, and then connect via the serial port on /dev.tty.wchusbserial410.
- You must have administrator rights to do this
