Is there any special patch for AMD FX-6300 or Ryzen 1700X CPU's hackintosh for its 32-bit application ?

 

no

Apple has removed some 32-bit libraries depend

 

libraries：dylib、Frameworks

 

macOS 10.15 will completely remove the 32-bit library

 

https://appleinsider.com/articles/18/06/05/mojave-is-apples-last-version-of-macos-to-support-32-bit-apps

 

You can Try run QuickTime 7 on Intel Machines，Also can't work.

@Meowthra for some reason mach_call_munger and unix_syscall never gets called on AMD and we get a panic after opemu_utrap (saved_state) on  thread_exception_return () like Shaneee and others reported. Are the functions hooked correctly?

AVX/AVX2 instruction set for Pentium / Celeron CPU

Intel Haswell Pentium / Celeron Series Or older processor expansion instruction set Emulation

OS X 10.12 or later Pentium and Celeron Unable Support
Because OS X 10.12 and later Haswell OpenGL Driver Requires AVX Instructions
So the Processor Must Support the AVX Instruction Set.
Unless there is a Source code that can be Recompiled.

Can you please make it clearer or tell me where to look? Is this only for Haswell or older devices? Can it enable QE/CI on a G4600 (HD 630) desktop?

The recent World of Warcraft seems to use CPU features of newer Intel CPUs that my Mac Pro 3,1 lacks. I tried to use the opcode emulator to bypass this issue but it keeps crashing. Any idea what CPU feature World of Warcraft could use that is not supported by my CPUs? In Windows it is indeed running fine.

Question: does VSSE4.2 and SSE4.2 mean the same thing?

[foojitsu1]

Hi- Sorry to stir up a dormant thread, but are there any plans to update OpCode Emulator for OpenCore? More specifically and possibly, one that would be compatible with cMP? Looking for an AVX Emulator to see if it's a valid "workaround" for loading UAD Luna software. Thanks in advance!

Hi Meo,

 

I hacked rex into vex registers to make it work on a intel c2d without vmx.

maybe this is a very old cpu and not worth it.

 

Playing a bit more with code the emulator works but i'm getting always crashes on trustd daemon. Only me or same for others using the driver ?

Hey @Meowthra I was wondering if this could be modified to emulate Intel's vmx CPU feature for AMD SVM CPU instructions, so AMD hacks can use virtualization in macOS.

I just found "not crashing CPU-X version" under this link 3-rd comment. It works under latest Mojave, not all fields are correct thought. Attaching app in case link went dead.

Inside src.zip i've included the emulator binary (move both kexts to clover Kexts/other)

 

this is made for core2duo cpus with no SSE4.1

 

the config.plist are kernel patches  for  10.14.2  - add them to clover before try to boot

 

this might also work with old macs and amd  cpus.

 

the emulator requires a vanilla kernel + cpu patches (check amd native kernel thread for other kernel versions patches).

 

boot with -v flag for verbose log

 

select kernel cpu patch in clover patches options

 

i found a bug in ioPresentment framework that prevents graphics from loading.

inside ioPresentmentCreateAssociationMap() the ioPresentmentFindAGDCMatch() returns error 0xe00002c2 (invalid parameter?)

Could someone rework OpcodeEmulator, so it’d work with MacKernelSDK and Xcode 12 compatibility. I have already done it, but I’m not coder/developer and it’d be better if someone more skilled did it.

Attaching my reworked version.

Clone latest Lilu debug and MacKernelSDK into OpcodeEmulator and build kext.

It compiles fine. There are some warnings.

Thanks @startergo I’ll give it a try. Those warnings are also present when trying to build OpcodeEmulator.kext from OP with Lilu version attached by @Meowthra

Sorry if this is wrong section but did you guys use the performance counters to calculate the CPU frequency accurately? I don't know how CPU-Z work currently but they did use performance counters before if I'm not mistaken.
