The VM will NOT start without the corresponding record in the Mac Keychain that contains a password to decrypt the TPM file. It is not quite easy to copy this record to a new Mac, but it is possible. We have prepared detailed instructions on how to do it in
this article.
But, there is no any info about in that KB. Only:
Important: it is not recommended to move, copy or clone a virtual machine with enabled TPM. Always have a backup of important information, especially recovery keys. When TPM is enabled, the virtual machine is restricted from running on other Mac computers, and by default, it cannot be started on another computer if copied or moved.
So, how we can transfer TMP password from one MacOS Keychain to another?
