HA OS Install for Raspberry PI 4 on Wifi


I’m trying to install the HA OS as per this link:

…but also trying to access the SSD to configure WiFi as per this link (part way down the page):

My desktop is a Mac Mini M1 and the problem is as soon as I flash the OS onto the SSD it becomes unreadable to the mac so I can’t configure the Wifi. Any suggestions? I stopped installing the container on a RP OS because I thought this may be the easier way to get setup. I might be wrong!
