How do I connect a Mac to another Mac as hard drive?

Can we still start a Mac as a slave or as a hard drive, to be connected to another Mac?

To elaborate:


If the Mac that you want to be the "disk" is an Intel-based one, then

  • If either Mac is running Big Sur or later, the connection must be a Thunderbolt one. Apple appears to have dropped support for FireWire and USB Target Disk Mode.


On the other hand, if the Mac that you want to be the "disk" is Apple-Silicon-based, then you can use a "USB, USB-C, or Thunderbolt cable".

So the way in which you get a Mac to act as a "disk" and the types of connections you can use now depend on what type of processor it has.
