Then you need to log into Recovery by doing the following First I formatted my external drive down to the bone. Here’s how I did it, but keep in mind that you need to perform every step from your M1. I figured that if I could get that far, then I could copy all of my old files over later. I simply wanted to externally boot into a fresh copy of 11.1. My goal was to simply make a bootable drive, with no saved data on it. So today I decided to strip the process down so that I could learn what might be going wrong. This always ended up with the above mentioned issues/errors.

Everyone was being told to copy over their data partition, either by using CCC or by using Migration Assistant, and then once that process was completed to go into Recovery and install a fresh new copy of 11.1 to their external drive. Many other people, both here, and on other Apple forums were having the same frustrating issues trying to make a M1 bootable external drive for their M1 also.Īfter thinking about what might be going wrong, I decided today to take a different approach to the issue. No matter what I tried to do I always ran into issues/errors, and upon doing a lot of research I quickly learned that I was not alone. I thought that this would be straight forward just like on an intel Mac, but it was not. One of the first things that I needed to do was to set-up a bootable external drive. Several weeks ago I bought a new M1 Mac mini.
