It appears to be launchd that makes use of SSSE3, which is actualy open-source (I haven't yet looked it up) - but even if we could patch it, there might be other (closed source) parts of the OS that make use of that instructions set, so an emulator might be the way to go.

One disadvantage would of course be that using an emulation will decrease peformance a little...

I took a look at the source of sse3 emulator for AnV's kernel (10.6.8) the procedure to inject the interrupt handler is the same in 10.7?

Yes these methods are still present.

For SSE3 Emulation INT 6h is overwritten with the adress of the interrupt handler, that passes the adress of the bad opcode to the actuall emulator that returns the emulation methods to the application and restores registers - principally the Kernel integration of a new emulator could be done the same way...

For details check it's whitepaper:

Someone around here who has an enslaved asm guru locked-up in the basement?!^^

The latest Kernel that I posted should no longer panic on version mismatch between Kernel & SleepEnabler.kext - no need to update that kext unless you want the warning to be removed from dmesg.

To disable Spotlight indexing on Lion:
sudo launchctl unload -w /System/Library/LaunchDaemons/com.apple.metadata.mds.plist

The blinking is still present and Finder freezes when I empty trash or do any activity. Any kernel I can test with the DP Finder and 32-bit mode?

I am now going to revert back to 10.7.2 and install 10.7.3 combo update and test that one to see if I get same results as 10.7.4

The ComboUpdate pkg does not run, the only way to upgrade is via Software Update?! It doesn't let me pick any drive and gives the error message: "Mac OS X Update Combined can't be installed on this disk. An error occurred while evaluating JavaScript for the package."

With a SSSE3 emulator, Phenom users would be able to run as good as bulldozer's?
I took a look at the source of sse3 emulator for AnV's kernel (10.6.8) the procedure to inject the interrupt handler is the same in 10.7?

With a help from ArchC or simple C -> ASM for easing the task of writing the "emulator", do you think this task can be achieved?

SSSE3 should not be mistaken by SSE3.

I know that, the question was about the method to inject the interruption handler, if its the same.

qemu - kvm as a processor emulator have a bunch of ssse3 implementations in C, it seems pretty well to me, guess it works fine. I can try to get the ASM for that instructions, but I'm not sure yet how to make the osx kernel use them =/

Anyone can have FaceTime/iCloud working here?
Thanks
