Creating Bootable Clone from Apple Silicon Mac

[mschmitt]

I saw the code for the registry error here, preceded by the comment:

PHP Code:

     * On kasan kernels, everything takes longer, so double the number of
     * timeout extensions. This should help with issues like 41259215
     * where WindowServer was timing out waiting for kextd to get all the
     * kasan kexts loaded and started.
     *
     * On legacy/x86 systems give a bit more time since we may be
     * booting from a HDD. 


The problem with not having the secure token on the clone is that I can't encrypt the data with File Vault. I don't like to have external disks lying around unencrypted.

I think I might have been able to repair that, but now I can't because it doesn't boot anymore.

I also think the secure token problem was created because I installed macOS over the cloned System.

It seems the use cases for bootable clones are reduced down to two now:

• Reinstall OS from clone <- can't anymore
• Boot when the internal SSD is completely toast <- can't anymore
• Boot to check things out on the data as it was at the time of the clone
• Boot when something goes catastrophically wrong with the data on the internal drive
