+Compiling the driver for macOS
+------------------------------
+
+First install the dependencies, most easily done with homebrew:
+
+    $ brew install libftdi-dev libusb-dev
+
+Adjust the Makefile, if necessary, to point at your ftdi directory:
+
+    $ mdfind -name ftdi.h
+    /usr/local/Cellar/libftdi/1.4/include/libftdi1/ftdi.h
+
+then, in your Makefile.macos:
+```
+FTDILOC = /usr/local/Cellar/libftdi/1.4/include/libftdi1/
+```
+
+Next build the executable:
+
+    $ make -f Makefile.macos
+
+If running it fails, you may have to run as root:
+
+    $ sudo ./infnoise
+
+Or you may have to unload the FTDI serial port driver:
+
+    $ sudo kextunload -b com.FTDI.driver.FTDIUSBSerialDriver
+
+Alternatively, FTDI have released the [D2XXhelper](http://www.ftdichip.com/Drivers/D2XX.htm), which may prevent the
+serial driver from grabbing the Infinitenoise device.

+Usage
+-----
+
+Usage: infnoise [options]
+Options are:
+    --debug - turn on some debug output
+    --dev-random - write entropy to /dev/random instead of stdout
+    --raw - do not whiten the output
+    --multiplier <value> - write 256 bits * value for each 512 bits written to the Keccak sponge
+    --no-output - do not write random output data
+    --daemon - run in the background. Output should be redirected to a file or
+    the options should be used with --dev-random. To reduce CPU-usage addition
+    af entropy is only forced after a minute rather than a second.
+    --pidfile <filename> - write the process ID to a file. If --daemon is used, it is the ID of the background process.
+    --serial <serial> - use Infinite Noise TRNG/FT240 with the given serial number (see --list-devices)
+    --list-devices - list available devices
