Lost Administrator Access(Apple silicon)

That has not worked since they split the System and Data volumes.

I haven't tried on an M1, but I don't think that will make a difference.

Also if you renamed the volume, then you may need to modify the path to the "Data" volume. The linked article assumes the default "Macintosh HD" volume is being used.

That's covered, just before the Restart heading.

From what you posted, you didn’t escape the spaces in the Volume name so it is looking for multiple paths breaking at each space.

And, if the volume is mounted as just “Data,” use that instead of “Macintosh HD - Data.”

The path is enclosed in double quotes so the path is Ok assuming the volume is named "Macintosh HD - Data".

While booted into Recovery Mode run the following command to discover the name of the internal boot volume especially if the name was changed at some point (one of the items should be the "Data" volume you need):

mount  |  grep  -i  volumes

This is normal since volumes get mounted at different locations with different names depending on whether you are booted to the volume or mounting it from Recovery Mode.

You can't find the file because you are looking in the System Volume. That's the difference in removing the file pre-Catalina and post-Catalina. The System Volume is locked down, so you'd never be able to delete that file. Under the split system, that file is located in the Data volume.

If you go through /System/Volumes/Data, you'll find the file at that path. That is where you are trying to get to in recovery.

Since you don't have an admin user, you have to delete the file in Recovery where the permissions don't restrict you from deleting the file. But, it won't be mounted at /System/Volumes/ in Recovery. It will be mounted to /Volumes/

I vaguely remember seeing just "Data," but when I checked by MacBook Pro (Intel) it had "startup name - Data"

I have not looked at my M1 Mini and it just has "Data," so that is where I remember seeing it.

I will have to update that User Tip. Thanks for the feedback.

So it is! I guess I I was tired.
