  1. About the Haswell-E Patch….. Any idea about what’s wrong with it?

    $ md5 /Volumes/Hackintosh/System/Library/Kernels/kernel
    MD5 (/Volumes/Hackintosh/System/Library/Kernels/kernel) = 1a2306e39c55551fc723c7fda153ae1c

  2. Hi Andrew,
    a while ago you sent me a patched Kernel 14.0.0 to boot with more than 16 cores.
    I wonder if you have any knowledge on how this kernel was patched or how to patch the Darwin 14.4.0 to run on more than 16 cores? I would be very grateful.

    Anyhow, I´ve got now Power Management on X9Dai (C60x) running, If you need infos for your readers, drop me a line, I´d be glad to provide my setup.

    Michael

  4. Seems like the 32 core patch is not working. Getting the same kernel panics as without the patch. (Fault CPU, aicpupm in backtrace). What could be wrong?
