macOS 10.12 and MacPro1,1/2,1

Bad news for everyone who still uses 65-nm intel cpu based on conroe arch (for example MP1,1/2,1).

SSE4 is being used now in system application and these cpus a missing it.

For example, trying to run macOS 10.12 on MP1,1/MP2,1 will give a panic because launchd process (init process, if it dies – kernel in panic) dies with signal 4 (illegal instruction).

Your only hope is when 10.12 released and sources code for kernel becomes available, if somebody will implement sse4,1 emulator (similar to sse3 emulation in the past)

    Thanks for clarifying the KP at boot.
    This also includes running macOS 10.12 DP in VMware Fusion on those machines.
    Is it something Apple could revert in a next seed?

    […] #Notes: Untuk saat ini, MacOS 10.12 Sierra DP1 pakai minim CPU dg instruksi SSE4.1, jadi untuk Arrandale based smisal Intel Westmare Pentium P6xxx yg msih SSE3.1 contoh punya Mas Fajar Aditiya Sukma harap bersabar nungguin “Emulator” yg jln di kernel Darwin 16.x. Penasaran nyicip, bakal ngadepin KP yg disebabin “lauchhd process, dies with signal 4: illegal instruction”. So, stay max di OSX El Capitan 10.11.x. Sumber: http://netkas.org/?p=1448 […]

    Okay! But what is with the MP 3,1?!? I searched in Intel Docs and found that SSE4 is supporter at Xeon 5400-Series?!? That’s only f*** marketing!

    Well hope that Source code for macOS 10.12 kernel will be open like iOS10 beta is now ….
