But... 10 00 00 00 10 00 00 00 00 01 00 00 00 10 01 08 doesn't work for me. No signal on VGA. I found that: 10 00 00 00 10 00 00 00 00 01 00 00 11 02 01 01 gave me signal on VGA output (connector with index 3). But when I apply it system always see VGA Display... even my monitor is not connected. It also disabled HDMI (from previous modification). Have you got any idea how to fix VGA? EDIT: I just realized that connector 0 could give me VGA output too.

timp Posted August 22, 2013 Share Posted August 22, 2013 Hay, Did you get the VGA port working? I've been having the same issue with a Dell 6970m card in my m6700. The card has the 6970m BIOS not the M8900. It only has 5 connection defined, not 6 as in the M8900. But if you are using the kext personalities it shouldn't make a difference, right? Guess it just missing the eDP connector for the IPS screen. I can get LVDS, DP and HDMI all working fine. I can also get an image on a monitor connected to the VGA port. The problem seems to be that the system can't read the monitors EDID when connected via VGA. Comes up as a 800x600 screen with or without the monitor connected. The name of the display is also missing when connected via VGA and the list of resolutions isn't what the monitor supports. It is odd that the VGA senseid is 8 in the BIOS, but all values in the kext tables are in the range 01 to 06. This is the index of the GPU's I2C bus that is used to read the connectors EDID right? My idea is that the driver somehow knows it can't read the EDID from VGA so just defaults to a preset list of resolutions. I've tried changing the senseId to the values that aren't used by LVDS,DP and HDMI but none of them seems to be the VGA port. I have a block diagram of the M6700. There is a DP to VGA converter on the motherboard between the card and the VGA connector. If it's an active converter, it's possible that the VGA connector should be configured as a DP, but I haven't had time to experiment and it maybe different on the M6600. Just and idea... Tim.

styrian Posted August 29, 2013 Share Posted August 29, 2013 @timp Hello! I had a similar problem with HD3000 on my Egde E320. I have reduced the ports of the framebuffer from 4 to 3, defined the third port for vga-output and set the forth one to zero. Perhaps you should try the same with ports, if you have some too much. Have you tried with the K3000m in your M6700 to switch to the SMBios of a MacPro? I see the possibility that the GK drivers work in an other way on 10 8.4, because there has been never a Quadro in an other Mac device then in a Mac Pro. A real Quadro card had ever great differences to other NV cards. As I believe, is it the same now within the Kepler generation. It also can not do harm to update the bootloader to one of the new versions here in the downloads, if you have not done it until now. Have fun!

xplus93 Posted June 8, 2014 Share Posted June 8, 2014 Hi, I have an M6600 as well. I have no idea what your talking about as far as cattail, or how to edit the frame buffer. I don't use vga, so, could you tell me how you got internal and hdmi working? Link to comment Share on other sites More sharing options...
M4ciek Posted June 8, 2014 Author Share Posted June 8, 2014 You've got how to do it in first post. If you don't understeand, sorry... it's not for you or you should learn something more about it. I abandon project of installation OSX on M6600... but maybe in the holidays I will try to install a newer version, because I still have this computer.

xplus93 Posted June 8, 2014 Share Posted June 8, 2014 You don't have to be rude. Apparently, I know more than you since I was able to get fully working sound and a trackpad with scrolling if we are going by your logic. I did read more about it, and you're advice didn't help. I'm sorry about your rudeness, but apparently forum usage isn't for you. Link to comment Share on other sites More sharing options...

jtrindle Posted December 24, 2018 Share Posted December 24, 2018 (edited) I have the Dell M6600 with ATI Firepro M8900 (ATI 6970M) adapter, and I've tried to get the VGA working under Yosemite, El Capitan, Sierra, and High Sierra with no success. I do have LVDS, DP and HDMI working with modified Muskgrass, and have with Cattail (which only reveals 3 ports instead of 4 in IORegistryExplorer). When I boot and then plug in the VGA, the monitor goes into power saving mode. If I try to boot with the VGA monitor plugged, in, I don't get any LVDS, DP, or HDMI . Has anyone made the VGA plug work with this laptop? Thank you! ...John Trindle config.plist.zip DSDT.aml.zip Edited December 24, 2018 by jtrindle Link to comment Share on other sites More sharing options...
