 # Installation 
 You have to install the MCC library (follow the installing instructions for [linux/macOS](https://github.com/mccdaq/uldaq) or [windows](https://github.com/mccdaq/mcculw)).
 
-For MacOs if you run into problems with the libusb library that was installed with homebrew, there is an issue thread on the uldaq repository.
