Citation: https://support.apple.com/en-gb/guide/security/sec59b0b31ff/... "The Secure Enclave Processor runs an Apple-customised version of the L4 microkernel."

From the rumor mill morgue, back in 2006 there was some speculation about macOS, err, Mac OS X transitioning to L4: https://arstechnica.com/staff/2006/06/4407/

    They hired a ton of UNSW graduates who had worked on L4 around that time.

Nice! Yeah, that's definitely modern enough. Do you know if it runs as a hypervisor in the Secure Enclave firmware? It seems like the processor itself is low-power enough that it might not have virtualization features.

    I am pretty sure there is no hypervisor. I am pretty sure the processor supports EL2 but it doesn't get used for anything to my knowledge.
