Mac OSX Lion on Lenovo H310 - USB Mouse Jittery using nVIDIA GeForce 8400GS

Recommended Posts

Hello guys, please help me to solve this problem:


I have PCI-e VGA with ZOTAC nVIDIA GeForce 8400GS @ 512 MB DDR3 64-bit.


I've using it on my Acer ASPIRE M1800 PC (nForce 630i Chipset with DualCore CPU E5200 @ 2.5 GHz, 2 GB RAM DDR2, 2 x 320 GB SATA HDD, DVD-R/W Dual Layer) and everything work fine with iATKOS L2 (Mac OSX Lion 10.7.2 - Upgraded to 10.7.3). With just adding my Device ID to NVDANV50Hal.kext on S/L/E and boot with "arch=i386 Graphics Enabler=Yes" ... all accellerations and resolutions work OOB fully Q/E & CI.


But now, I found some problems when using it on my new PC with this specs:


Vendor : Lenovo H310 Desktop PC

Chipset : Intel 82801G SounthBridge

Processor : Intel DualCore CPU E6700 @ 3.2 GHz

VGA : OnBoard Intel G41 (detected as unknown 64 MB on Snow Leo 10.6.2 & Lion 10.7.2)

HDD : Western Digital @ 500 GB, SATA-7200 RPM

Memory : Samsung 2 GB DDR3 Single RAM

Others : Lenovo 18" LCD Monitor, DVD-R/W, Realtek OnBoard Ethernet, Card Reader, PS/2 Keyboard & USB Mouse.

Misc : No AHCI Mode on BIOS (but just IDE), VT Tech, Video Mode Switch (between Onboard & PCI-e)


The installation succeeded; iATKOS L2 DVD using the OnBoard VGA.

Some problems occur when I decided to replace the OnBoard VGA with my 8400GS PCI-e. All accelerations & resolutions work fine with fully Q/E & C/I (just a same as above method), but wait... now i get very slow OS Performance and unfortunately my PS/2 Mouse & USB Keyboard couldn't run perfectly (jittery, acceleration problem, I couldn't move it on). Then, I try to replace the USB Mouse with PS/2 Port, using other mouse / keyboard but it doesn't work anymore. When using OnBoard VGA (1024x768 Native Resolution; X4500.kext compatibility issue, no Q/E & C/I) it works perfectly (Both PS/2 Keyboard & USB Mouse).


So, I assume that 8400GS VGA caused this problem.

(Additional: When booting with "-v" option, I got some outputs that ALPSGlidePoint, VoodooPS2SynapticsTouchPad, and ApplePS2Trackpad are loaded. I don't know what this mean, since I'm sure that my PC doesn't have this hardware. I've tried to remove it from S/L/E, but I found nothing there...!?)


Please, help me to fix this problem... Thanks very much, and I apologize for my bad English.

    • nvidia is not that fast for osx user...just wait another 24-48h and the new driver package will be released for the 17E202 build...
    • It seems nice that chris1111 provided a patch, but I can't -- in good conscience -- download a random binary file from github and run it on my system.    What is so proprietary about his patch that he can't include source? I think I'll wait until the updated driver comes out before I update...  Does anyone know where to look for updates to the webdriver from Nvidia? I've ever found a page that lists them, just links to the actual files to download, and that root is not 'browsable'. I'd like to monitor that site to see when a version is updated for the 17E202 build. Once that is released, I can update OSX and should be fine.  
    • hey MaLd0n  It's been a while since I used clover, so a lot of things went rusty. Can you please look at my setup and guide/help what should be done next?  https://fex.net/354949878474?fileId=441517695   Current setup:  GA-Z97X-UD3H Xeon e3 1245v3  Msi GTX 1050ti Gaming X
    • Hi @fabiosun and thank's for your patience with an old and stubborn man.   I am 100 % sure that my MSR 0xE2 register is unlocked thank's to you.   My system is 100% stable and I haven't had one kp with this configuration in the last two weeks.    I'm now running without TSCAdjustReseat.kext and I can't se any issues in performance with or without that kext. What I however can se is that the amount of total energy consumed during the test-cycle are 10 times higher without the kext (three times Cinebench CPU and two times Luxmark open CL) as you can see in the output from my AppleIntelInfo.kext attached in my earlier post.   I have tested running Cinebench five times in a row with or without TSC kext and have exactly the same performance (see attached files). Temperature is not a problem at all.   Everything seems to be fine so I guess I have to wait and see if upcoming 10.13.5 maybe recognise Intel Xeon w series processor as native.     
    • Tried with HPET enabled and disabled so I don't think it's that. I'd tried with bus ratio before to no effect but wouldn't hurt to try again. The clock runs at the correct speed.
