The random-seed will eventually really be random, but the Intel Secure Key Technology is not supported on the processors that are used in the MacPro[1/2]. You can verify this for me by running the commands below:
sysctl -n machdep.cpu.features
sysctl -n machdep.cpu.extfeatures
Edit: This has been confirmed by Dan M. and blacksheep. Thanks guys!
When will it work? The usual answer to this kind of questions is; When I am done. But seriously. It will just take a little bit longer because now I had to disassemble Apple’s boot.efi and convert their assembler code into compatible C code.
The debug messages are now switched off, by default, but you can enable them by changing a the DEBUG_LDRP_CALL_CSPRINTF compiler directive from 0 (zero) to 1 when you need them.
