No luck with EVGA GeForce GTX 660 SC 3072MB on 10.8.3

6 posts in this topic

Hi

 

After 3 days of searching far and wide on the internet for solutions to enable my GTX660 SC upgrade to function on 10.8.3, I have become unsuccessful. I am left with no choice but to ask for the forums' help.

I need to know whether or not the (3072MB version) card is supported, and if so what is the best route to go about enabling that card to run. These are following steps I have done so far:

1) With my GTX480 card in place, I installed 10.8.3

2) I installed NVIDIA CUDA drivers (released on 3/15/13)

3) I attempted to install NVIDIA 304.00.05f02 drivers, but the installer said that my current drivers were already up-to-date.

4) I then switched out my GTX480 for the 660 in my hack. Every time I try to run off the GTX660, I get a kernel panic stating: "System uptime in nanoseconds" regardless of what boot flag I use, i.e.: -v -x GraphicsEnabler=No npci=0x3000 cpus=1. I even get the same message kernel panic as soon as the Apple logo screen shows up.

I need to know what current market graphics card is proven to work in 10.8.3 because I am eager to buy it and return my current 660 back. I am in the market of getting anything up to a GTX 670 and only if it is proven to work in 10.8.3 without much trouble. If anybody out there has any knowledge of what direction I should take I would gladly oblige. Thanks

Can't think of what might be happening there. I went from a 460 to a 670 without any hassle in 10.8.2 (and have since updated to 10.8.3 fine). I just turned off GE, swapped out the cards and booted up.

Hey thanks for the help, but I have already resolved the issue on another forum. I realized that removing the NvClockx kext from E/E in the root directory was the cause, and also the boot flag GraphicsEnabler=No was case sensitive. I was actually typing it in all lower case, so I would always pull up a grey screen after the Apple logo. 10.8.3 now fully recognizes my card now.

The same thing happened to me when I got my GTX 660. Luckily my hack was clearly freezing when loading NVClock.

If you need GPU temp monitoring then use this https://github.com/kozlek/HWSensors

 

Thanks. I actually was checking this out a couple of weeks ago by some guy named kloezek (however u spell his name) on another forum. I never took the time out out to figure how to install it yet. How'd you do it?

 

S/N: I was unhappy with the X660 so I returned it and purchased a X680, but it works as well in 10.8.3.

      I have a Mac Mini 2006 (upgraded) with Intel GMA950 graphics, running MLPostFactor 10.8.5.  It is connected to an ASUS VS197 LCD panel using DVI-D.  This is natively a 1366x768 panel that is recognized and works fine.
       
      However, the other choices for resolution are 4:3 800x600 and 1024x768, and then the oddballs 832x624 and 1360x768.  None of these are useful as a low-resolution widescreen for gaming or watching DVD content.  Specifically I want to get access to 848x480 or 854x480, and also 1024x576.  SwitchResX makes these choices available, but it doesn't work with a "full screen" game, presumably because the game directly queries OSX Display to get a list of valid resolutions and SwitchResX is bypassing that system instead.
       
      So the solution is obvious: buy a new computer pull the monitor's EDID data, hack it to enable new resolutions, and then tell OSX to use this custom EDID instead of the one retrieved from the monitor.
       
      Following the steps of the EDID injection guide, here is where I am:
       
      * Retrieve EDID, DisplayVendorID etc from ioreg.
      00 FF FF FF FF FF FF 00 04 69 F2 19 24 94 00 00 31 16 01 03 80 29 17 78 EA F5 45 A4 55 50 9E 27 0F 50 54 BD EE 00 81 C0 01 01 01 01 01 01 01 01 01 01 01 01 01 01 66 21 56 AA 51 00 1E 30 46 8F 33 00 9A E6 10 00 00 1E 00 00 00 FD 00 32 4B 18 53 11 00 0A 20 20 20 20 20 20 00 00 00 FC 00 41 53 55 53 20 56 53 31 39 37 0A 20 20 00 00 00 FF 00 43 43 4C 4D 54 46 30 33 37 39 32 34 0A 00 F1 * Use an EDID editor to enable new 848x477 and 1024x576 resolutions.  (Verify with an online EDID tool, and compare to the previous version)
      00 FF FF FF FF FF FF 00 04 69 F2 19 24 94 00 00 31 16 01 03 80 29 17 78 EA F5 45 A4 55 50 9E 27 0F 50 54 BD EE 00 81 C0 4B C0 4B CA 4B CF 61 C0 61 CA 61 CF 01 01 66 21 56 AA 51 00 1E 30 46 8F 33 00 9A E6 10 00 00 1E 00 00 00 FD 00 32 4B 18 53 11 00 0A 20 20 20 20 20 20 00 00 00 FC 00 41 53 55 53 20 56 53 31 39 37 0A 20 20 00 00 00 FF 00 43 43 4C 4D 54 46 30 33 37 39 32 34 0A 00 47 * Create a new subfolder and plist within /System/Library/Overrides/Display/ containing the new EDID string and monitor name.
      * Reboot.
       
      Now the problems begin.  Even though the plist file is being read (which I know because the Monitor Name has changed in Displays), the custom EDID is not being used.  When I dig into IORegExplorer I am able to come up with AAPL00,EDID string and it is the unmodified one read from the monitor.  I even tried a plug-and-unplug while OSX is running, and also tried to reset the SMC and NVRAM, but no dice.
       
      Do I need to start digging into DSDT hacking?  Is the Intel driver pulling down EDID during boot and I need to override it somewhere else?  What am I missing here?

      Hello,
       
      I've been attempting for the past few days to install OS X Mountain Lion on my Lenovo Thinkpad Edge E530 with little success. So much so that I've finally decided I'm probably out of ideas and created this forum post requesting help.
       
      My Laptop Specs are:
       
      Intel Core i3-2328m (Sandy Bridge CPU at 2.2GHZ with support for SSE2 , SSE3 and SSSE3)
      8GB RAM
      500GB Hitachi Z7K500 HDD
      Lenovo 627226G Motherboard (Intel HM77 Chipset)
      Intel HD Graphics 3000
       
      More Detailed Specs ---> https://drive.google.com/open?id=0B-GXUa1I8xyDZU1SdklDSlhER2c
       
      So far , I've attempted to install iAtkos ML2 and ML3U via USB and so far both have worked up until the first sighting of the apple logo then the laptop restarted. In both cases , I was using a separate USB with chameleon bootloader on but in the instance where I tried to use the onboard bootloader on ML3U , I hit enter and the screen simply remained black.
       
      Any help would be much appreciated
       
      Thank you for your time.

      Hey all,
       I built my first Hackintosh back in 2012 and its been runner amazing. Thank you again for the awesome guides and forums that made it all possible. I have however hit the end of this builds software limits. I am still running 10.8.2 mountain lion on the machine. I would like to update to Sierra and want to make sure I am clear on the procedures. Now that it seems like everything is could based and no longer get physical versions of OS.
      currently i am backing up the system using and external drive and "carbon copy cloner" as shown here: http://www.macbreaker.com/2012/06/backup-your-hackintosh-with-carbon-copy.html
       
      My question is should i follow the set via the App store updates, Wipe the system and start over or is there a better way to achieve running Sierra on my machine?
       
      Here are my build specs:
      Processor name: Intel Core i7
      Processor Speed: 3.50 GHZ
      # of cores: 4
      memory: 32gb
      Boot rom version: insanelymac.com
      Graphics Card: Nivda GeForce GTX 670
      System Version: OSX 10.8.2 (12c60)
      i have also attached screen shots of the spec to further help:
       
      Thank you for taking the time to help me out with my build. look forward to getting this bad boy updated.
       
       
      Mahalo,

      While most of the VMWare guest hardware is virtualized, the guest VM CPU reflects the same CPU features the physical host CPU has.
      This guide details the additional work that is needed to run OS X 10.8-10.12 with an AMD CPU under VMWare.
       
      If your AMD CPU supports SSE3 and SSSE3 (and SSE4.1 for OS X 10.12):
      The installation should be pretty simple:
      1. Install VMWare Workstation 8.0.6 / 9.0.4 / 10.0.4 / Player 6.0.4.
      2. Run VMWare Unlocker 1.3.0.
      3. Prepare an installation ISO from the untouched 10.8 (Mountain Lion) DMG using dmg2img.
      4. Create a new VM (select "Mac OS X 10.8" as the guest operating system).
      5. Set your 'number of cores per processor' to 1 (the number of processors can be set to more than one).
      6. A. For OS X 10.8-10.11:
      Open the .vmx file of the virtual machine and add the following lines:
      cpuid.0.eax="0000:0000:0000:0000:0000:0000:0000:1011" cpuid.0.ebx="0111:0101:0110:1110:0110:0101:0100:0111" cpuid.0.ecx="0110:1100:0110:0101:0111:0100:0110:1110" cpuid.0.edx="0100:1001:0110:0101:0110:1110:0110:1001" cpuid.1.eax="0000:0000:0000:0000:0000:0110:1111:0001" cpuid.1.ebx="0000:0010:0000:0001:0000:1000:0000:0000" cpuid.1.ecx="1000:0010:1001:1000:0010:0010:0000:0011" cpuid.1.edx="0000:1111:1010:1011:1111:1011:1111:1111" (this will identify the guest CPU as an Intel Core 2 Merom, and will help you avoid the 'The CPU has been disabled by the guest operating system. Power off or reset the virtual machine.' error)
       
      6. B. For OS X 10.12 Sierra:
      cpuid.0.eax="0000:0000:0000:0000:0000:0000:0000:1011" cpuid.0.ebx="0111:0101:0110:1110:0110:0101:0100:0111" cpuid.0.ecx="0110:1100:0110:0101:0111:0100:0110:1110" cpuid.0.edx="0100:1001:0110:0101:0110:1110:0110:1001" cpuid.1.eax="0000:0000:0000:0001:0000:0110:0111:0001" cpuid.1.ebx="0000:0010:0000:0001:0000:1000:0000:0000" cpuid.1.ecx="1000:0010:1001:1000:0010:0010:0000:0011" cpuid.1.edx="0000:1111:1010:1011:1111:1011:1111:1111" (this will identify the guest CPU as an Intel Core 2 Penryn which supports SSE4.1)
       
      7. If your Hardware compatibibility is set to Workstation 9.0 (virtualHW.version = "9") or 10, you must also add the following line:
      featureCompat.enable = "FALSE"

      8. You can now boot from the ISO and proceed with the installation.

      9. Even though I could complete the installation without a hitch with my A8-5600K, a few applications consistently crashed (e.g. Grapher), this was resolved by replacing the kernel with a modified kernel that emulates all missing SSE3 / SSSE3 instructions (see below).


      If your AMD CPU does not support SSSE3:
      You need to replace the kernel with one that has SSSE3 emulation (see below),
      the easiest way to do it is to use another computer that has SSSE3 to create the virtual disk and replace the kernel.
      1. After you have a working OS X machine, update to 10.8.5, make a copy of the virtual disk and attach it to the same VM.

      2. Change the os settings to show hidden files (see here), and delete the hidden 'mach_kernel' from the root folder of the attached disk.
      (alternatively, use the terminal to perform this, e.g. 'sudo chflags nohidden mach_kernel' or 'sudo rm mach_kernel')

      3. Put the modified kernel (see below) instead of the one you just deleted (use the same file name).

      4. Delete the old kernel cache by deleting the content of the '/System/Library/Caches/com.apple.kext.caches/' directory.

      5. Optionally: hide back the kernel (with 'sudo chflags hidden mach_kernel').

      6. Create a new VM, update the .vmx files to include the 8 cpuid.* lines from above.

      7. You can now use the attached disk to boot OS X 10.8.5 from a VM hosted with an older AMD CPU that does not support SSSE3.

      Tested With A8-5600K, A8-3850 and VMWare Workstation 8.0.6 / 9.0.4 / 10.0.4 / Player 6.0.4

      Modified Kernel:
      For your convenience, I have created a modified 10.8.5 kernel (a.k.a. xnu-2050.48.11) specifically to be used with VMWare, and attached it to this post.
      The only modification to this kernel is that it includes OpEmu3, the SSE3 and SSSE3 emulator created by Sinetek and AnV (thanks guys!).
      This emulator is only used when necessary (i.e. if your CPU support a specific instruction, the emulator will not be used to execute it).
      The source code to OpEmu3 is available here and my adaptaion to 10.8.5 is available here.
