Can’t delete file on “/usr/share/file/magic” location

/usr/share/file/magic is stored on the read-only boot volume. SIP does not make the boot volume read/write.

You can only delete things on the read/write Data volume.

Besides /usr/share/file/magic is needed by the 'file' command, and maybe a few other utilities.

I think it was with Catalina 10.15, the boot volume was spit into a read-only partition for macOS install, and a Data partition for user data and files that need to be modified, such as logs, caches, .plist, etc...

Then I would backup your Mac, and "Nuke & Pave" the system via Recover Mode. Then restore your data.

By "Nuke & Pave" I mean totally erase the disk. All partitions, not just a single partition or single volume. The entire drive. Install a clean version of macOS. During initial startup, when asked if you want to transfer data from another Mac, point to your backup disk.

Since Murphy's Law does not care if you have led a good life, make 2 backups, going to 2 different devices, using 2 different backup utilities, so you never have just 1 copy of your data. All of the data restored will end up on the read/write Data partition.

Why?

That file is part of the operating system. Even disabling SIP is not enough.

It would be better to explain why you want to delete it and then we can give you better alternatives.

Are you using the terminal for your deletion attempt?

I didn't ask what file you want to delete. I asked why?
