 ## Background
 Inspired by Sam Smiths [PiNC](https://github.com/phuedx/pinc) I wanted to make a easy way for everyone (not just developers) to try out different internet speeds.

 This is how I do iyt on my Mac. First make sure you have your SD card inserted. Then use `diskutil list` to find the disk. On my computer it's mounted as */dev/disk2*. Then to copy and compress it I use:
 
 ```
-sudo dd if=/dev/rdisk2 bs=1m | xz -T 0 -9 -e > /Users/peter/Desktop/pi3-version.xz
+sudo dd if=/dev/rdisk2 bs=1m | xz -T 0 -9 -e > /Users/peter/Desktop/humble-version.xz
 ```
 
 Note that I've changed */dev/disk2* to */dev/rdisk2* to make it read only.
