I recently inherited my wife's old mid-2010 (7,1), which I'm in the process of upgrading. I'm relatively unfamiliar with Macbooks, and I was wondering about setting it up in ways similar to my other machines running Linux.
I have FileVault turned on, but I was wondering if it's possible to take the security one step further by mounting the boot volume on a usb or sd card. That way the machine would only boot if the said volume was inserted AND the correct password was provided.
I'm not sure if macOS has a utility for achieving this, or if it can be setup this way at all. It appears that Apple's "Fusion Drives" implement a logical volume management scheme that is presumable capable of this
