Bootable USB creation FAIL on M4 Mac mini for macOS Sequoia 15.1

When creating a bootable USB on a M4 Mac mini the process fails giving the error below

Failed to extract AssetData/boot/Firmware/Manifests/InstallerBoot/* from update bundle

The bless of the installer disk failed.

I have tried downloading the installation app multiple times and via the terminal commands as well. Then tried multiple USB drives, and USB C directly plugged to mini. None of these attempts have worked out so far.

Please let me know if there's a workaround.

Mac mini, macOS 15.1

Report this to Apple as a " Bug Report " , link below

I say this, having tried, on a M4 Mac Mini, already updated to Sequoia 15.1 build ( 24B2083 )

Even giving Terminal " Full Disk Access " from Privacy and Security Before attempting to create the Bootable Installer it still failed

I can't see anywhere in the installer package that this path exists:

AssetData/boot/Firmware/Manifests

No part of it even.

Where are you seeing it?

It's definitely not a Mac mini or M4 specific thing. I've seen this on both an Intel machine and an M1 Air.

Same problem with the exact same errors on both my M4 Pro mini and my M1 mini. Followed Apple's instructions to the letter.

Exact same issue on a days old MacBook Pro M4 Max.

Me too. The same exact issue on a new M4 Mac mini

Now that 15.1.1 is released, hopefully the problem is fixed. I will try to over the weekend if nobody else get to it before that.

Mac OS 15.1.1 Is it working now?

How to use it properly as a boot disk?

I'd appreciate it if you could tell me!
