It´s only possible if your CPU does support SSSE3. (Bulldozer for example)
I don´t know you CPU so i can´t tell you if your cpu will be able to do but if it´s not a relative new cpu it will not support it.

Thanks for replying:

I have this: AMD Phenom(tm) II X6 1045T Processor × 6

This CPU doesn´t support SSSE3, so there is no chance to run it in 64 bit kernelmode in the moment.

Thanks for the clarification. I'll be buying an intel set-up then!

I think that bug should be fixed with latest build - although some further testing is needed.

My own experience is that my Bulldozer Hackintosh is finally running very stable & I am able to use all my software without any limitations. :)

People with other demands (software I am not using etc) may have a differing expierence - dunno...

Me too. :D
Anyway Intel is the better way to go, if you consider using OS X as your main operating system.

For example keep in your mind, that we may never be able to run Mountain Lion on our AMD machines (this ain't that unlikely for some reasons), any system update can cause problems i.e. depencies that cannot be solved until the source code for a new Kernel version is released (often some week after the release of the corresponding system update) etc.

Of course if your mainboard would support a Bulldozer upgrade (bios update etc) & you want to use Lion, this could be a "cheap at purchase" alternative.

Yes. 64-Bit software works.

No 64-Bit kexts.
The Kernel is i386 only. Kernel Extensions made for X86_64 Kernel only will not work.

Yes but not 100% ootb.
Running 32-Bit software requires the SYSENTER opcode, which is not avaible on AMD CPUs in 64-Bit enabled system mode.
Sysenter traps have to be patched in dyld & libsystem_kernel.dylib for 32-Bit Apps to work in compatibility mode.

Those problems are -legacy mode only.

Most likely yes - of course: no warranty for anything related to those Kernel. ;)

what is the function of -legacy ? and how can I drop it ?

Somehow I lost my previous account. Asked to reset my password but the new one never comes. Anyway, I'm back. Thank you again, RAW X86: your new updated kernel did the trick. Now i'm running 10.7.4 and the permissions bug is gone for good.

Gils, i'm an AMD stubborn, and i'm not exagerating: think i'll rather buy a piledriver set than change to intel; the price/performance ratio still pends to AMD side and i still have faith that the newer AMD CPUs can make through this tribulated transition to 64-bit kernel and extensions. As a matter of fact, i can tell i totally agree with you as far as OsX86 user experience is concerned: i have a hackintoshed atomN450 netbook, and it causes me far less trouble, runs 64-bit kernels and extensions and performs better than under windows7, even without current native suport for this CPU.

Uchihaxyz: Answering directly to your question, -legacy is the boot flag that forces your system boot 32-bit. I think RAW meant 32-bit mode when he said legacy mode. You can't "drop it" on an AMD system, unless you have a ssse3-enabled CPU (buldozer family). A couple of days ago, before the answer of RAW and his upload of his uptaded kernel, i had updated again to 10.7.4. The permissions bug discussed was there and didn't go away, but i tried a new approach to the core apps crashing issue: installed all i need when was still running 10.7.2/bronzovka's V4, and didn't change the original finder, relying on path finder (paid program, 30day trial) to do the finder thing. Worked surprisingly, I don't know how or why, and i could start and quit core service apps anytime I wanted to. But, as I needed airdrop to work, I called dp2 finder back and the crash issue returned. Besides this, I updated the kernel to the latest RAW's. Maybe the return of the crash bug is related to former, to the latter or to none (or both) of them. Who knows? But worth a try, if you have patience and a good backup for your data.

Asking to RAW X86 again: is it possible to enable iCloud/Facetime with your kernel? Appstore and iTunes store work like a charm with the en0/built-in ethernet Yes/latest chameleon/smbios patch, but iCloud/Facetime refuse to accept me to log in. In fact, i have this problem with my atom netbook too. Do iCloud/Facetime work only with vanilla kernel, perhaps?

Is anyone working on SSSE3?

Anyone recommend an alternative ATI kext?

Yea. I am also looking forward to these.
The so far leaked information on Vishera sounds very promissing.

Specialy thosen 83*0 with 95W TDP / 16MB cache could earn AMD a good market position one more time, if sold for a reasonable price. :cool:

Actualy iCloud doesn't work on my Xeon Workstation too.
Might be fixable, but I haven't ever cared any further about these programs, as I am not interested in using them anyway...

Does not look like if there is someone, with the necessary skills, who's currently into this..

Higly recommended not to use any extra kext.
The HD6850 should work ootb. :)
