Boot macOS on Lenovo machine from hard drive of MacBook pro that is dead I have a Lenovo system with Ubuntu installed on it.

What I'm trying to do is use the Lenovo system to boot macOS that was installed on a hard drive of a MacBook Pro that died. 

I saw several posts on creating bootable drives or backing up data from dead MacBooks, but none that specifies how you can boot into hard drive of a MacBook from a Lenovo (or any non-Mac system).
Basically an unmodified Lenovo won't read the boot information on a mac os formatted drive, so this won't work.

To read that mac drive, put it into an external drive enclosure and connect to a mac. Success here will also depend on having the user names and passwords as necessary.
