Hey, that's interesting. Thanks for your contribution!
Are you really able to execute SGX instructions on that machine? There could also be a bug in my testscript because I haven't seen a SGX 2 board from 2015 yet.
I believe the output above of the test-sgx is accurate, and the processor on this Mac does not support SGX. According to the following list this MacBook Pro (Retina, 15-inch, Mid 2015) has an i7-4xxx processor that is not listed in the ark.intel.com database.
I have a MacBook Pro "Core i7" 3.1 13" Early 2015, which has another processor (I7-5557U) not supported either in the Intel database, and the output of the test script shows sgx available: 0 like the one above.
I don't think that's a bug as SGX minimum is required CPU with Secure Key, I also got the rMBP mid-2015 with R9M370X graphics card model, but under ubuntu system, I can only install SDK for compiling but only can run in simulation mode. PSW install definitely fail on this one.
