Cannot mount latest image on MacOS to add wifi settings

Installation Home Assistant OS

Not sure where the problem lies, so I’m hoping someone here can help me figure out what to try next.

I am trying to burn the latest image to an SD card, but after the burn, MacOS throws up a “cannot read this disk” error so I can’t mount it add the Wifi information to allow it to connect to my router, so I basically can’t reach the Pi at all to see if it’s having any trouble booting up.

I have an original Raspberry Pi 3 B from 2016 with a 16GB SanDisk SD. Image is hassos_rpi3-1.12.img. I’m using Etcher 1.4.6.

I did manage to get a look at the disk image through the MacOS disk utility. There are about 8 partitions; it looks much more complex than it needs to be for just a little Pi. Might be that MacOS can’t handle an SD card with multiple partitions?

Are we talking about a HassOS image here?

If so you do it by using a USB stick. It’s in the getting started instructions. Step 3.

And this is a good tutorial too (not MacOS but you get the idea). The video should start playing at the relevant part @ 1m39s:

Yes, HassOS image. I’ll try the USB stick approach. I somehow completely missed that and was following instructions for editing a file directly on the SD card. Thank you!

I just tried the USB stick approach. I ended up creating two files on the drive in the /network folder because the file name in the video was different from the written instructions (system-connections vs my-network). The Pi comes up with a red light and an occasionally blinking green light, but it’s not connecting to my wifi router.

Do you think that Etcher burned the SD card correctly? Is the warning about not being able to mount it normal?

Any other thoughts on how I might troubleshoot this?

I found part of the problem. I put the Pi on a monitor and keyboard and noticed there was an unmounted directory at /mnt/config. It looks like the USB drive is not mounting at start-up. I was able to mount it manually, so the drive is accessible. Need to figure out now why it won’t come up on its own. Actually, first I need to see if I can manually start the network now that the drive is mounted.

Noting here for future readers that I was able to connect to wifi by adding hidden=true to the [802-11-wireless] section of the network config. I never broadcast my SSID and it didn’t occur to me that most people probably do and that the OS would not connect without me telling it that the SSID was hidden.

It’s working perfectly, the disk is in a format unreadable by the MacOS …as you’ve found :slight_smile:

so is it possible to mount the boot partition on Mac somehow? Or do I need to use the USB drive method?

So how can I put file from my Mac into it
