Share Internet Between macOS and a Raspberry Pi Zero Over USB

If you’re a fan of the Raspberry Pi, you might have stumbled upon my tutorial for interacting with a Raspberry Pi Zero using nothing more than a USB cable. If you recall, the standard Raspberry Pi Zero has no WiFi, no Bluetooth, and no Ethernet.

Alright, so let’s assume that you’re able to interact with your Raspberry Pi Zero. Now what? How do you update it, download new software, or work on some awesome projects that might require internet in some fashion?

Well, you could take a look at my tutorial titled, Three Simple Ways to get Online with a Raspberry Pi Zero IoT Device, or you could share the internet of your host computer without having to purchase any extra hardware.

In this tutorial we’re going to see how to share the internet from our host device, assuming that host is macOS.

Connect To A Raspberry Pi Zero With A PiUART Module

As you’re probably well aware from my previous Raspberry Pi articles, I’m a hoarder. I have several Raspberry Pi Zero as well as the wireless edition and various attachments that go with them.

When I was first getting started with the original Pi Zero, I had a tough time trying to figure out how to connect to it. I mean, how do you connect to something that doesn’t have some kind of internet connect?

I had written two articles previously for connecting to a Raspberry Pi Zero. The first titled, Connect to a Raspberry Pi Zero with a USB Cable and SSH, demonstrated how to connect with nothing more than a USB cable. The second titled, Connect to a Raspberry Pi and Pi Zero with a USB to TTL Serial Cable, demonstrated using GPIO pins and a serial cable to connect.

We’re going to simplify the connection process by using a nifty PiUART module and eliminate any complicated wiring or software configurations.

Auto Attaching USB Storage To A Raspberry Pi Running Linux

I’ve written a few articles about how I’m using my many Raspberry Pi units. Recently I wrote about using a Raspberry Pi as an automatic network backup server, but I didn’t talk about expanding the storage beyond the micro or standard sized SD card. What if you want to utilize a much larger USB hard drive or thumb drive? By default Linux won’t mount the drive, and heck, it may not even be in the correct format.

We’re going to see how to format a USB drive, mount it on a Raspberry Pi, and then auto mount it every time the Raspberry Pi reboots.
