Using SSHFS to mount your Raspberry Pi's home directory on your Mac
It is useful to be able to mount your Raspberry Pi's file system on your Mac's desktop. The Raspberry Pi is ready to rock-'n-roll but some work needs to be done on the Mac. This gist assumes macOS Mojave 10.14. Your mileage may vary on earlier or later versions.

You can make your life quite a bit simpler if you set up SSH on your Mac so that it can login to your Raspberry Pi without needing a password. Follow this tutorial.
The tutorial assumes two Raspberry Pis but there is no difference in approach if you use a Mac and a Pi, or two Macs.
