tim.shippam Posted April 22, 2025 Share Posted April 22, 2025 (edited) Hey, Currently installing with a single CPU osx so I couldn't get any screenshots but as the title states. The minute I put my second CPU tray in it doesn't boot. Last thing it said was keep alive and change to something else. Any ideas? I am using one of the ones off GitHub. But I can't remember which one once the installation happened I'll update the thread. But any ideas welcomes! Update ... Right so my specs are as follows, Z640 x 2667v4 128gb ram AMD RX5500xt https://github.com/HJebbour/HP-Z640-Hackintosh Using this. Changed the CPU flag and add -v plus added agdpmod=pikera for the GPU As I said above boots perfectly with CPU1 installed the minute add CPU2 in get just reboots. I don't understand why. I've changed the smbios around and they didn't change anything. Any ideas welcomes thank you.

tim.shippam Posted April 28, 2025 Author Share Posted April 28, 2025 Fixed it... Anyone who is trying to use this with a Dual CPU Z640 make sure you add AppleMCERReporterDisabler.kext and CpuTscSync.kext. Make sure AppleMCERReporterDisabler.kext is the first kext in your plist. Also worth changing your SMBIOS to iMacPro.1,1 I can upload my efi folder if needed. This is all thanks to oloshh from reddit so thank him not me for sorting out this all.
