    HP Elitebook 8570w with Quadro K2000M

    I've since given up on it, unfortunately, and went back to the Windows install on that laptop. It was just too frustrating after working on it for 3 weeks straight and getting nowhere. FWIW, I booted from a Linux live USB at one point and it identified the internal display as using an eDP connection instead of LVDS. Maybe that was the key, but I did try specifying the port as an eDP with a hotpatch. It would show my changes in ioreg, but it made no difference. Whether or not I was doing it right is another matter, but I was getting no answers anywhere.

    The AMD FirePro M4000 card arrived, and it's installed. Now, at the same part of the boot process where the internal display previously turned off, now the system reboots. I don't get it. I have no Nvidia-specific kexts or config.plist entries. What Mac model with AMD graphics would be good to use for the SMBIOS, assuming that's the issue?

    I ordered the FirePro M4000 MxM card, I'm really hoping it "just works" and that I don't have the same problem. It's apparently similar to a Radeon HD 7770M. I'm very skeptical, however. Anyone else have any predictions on it working?

    So I installed High Sierra on another volume, installed the web drivers, and it was no different. The DSDT/SSDTs for this laptop are a little odd when it comes to video. The PCI slot is identified as "PEGP", and there is a GFX0 device under it, which macOS seems to see as the graphics card. However, there is also a "DGFX" device entry. In one of the SSDT tables called "SSDT-2-NVIDIAGF.aml" which I imagine is obviously related specifically to the graphics card, DGFX seems to be what it refers to as the graphics card. This apparently is odd when it comes to Hackintosh stuff, since I can find few references to it when searching for info on DSDT/SSDT patching. So I thought a possible solution would be to rename the present GFX0 to GFX1, and DGFX to GFX0 in the DSDT.aml and SSDT-2-NVIDIAGF.aml and throw them in the patched folder. This also failed. If I don't get this figured out soon, I may pick up the AMD MXM card that is compatible with this laptop, which is a FirePro M4000, and hope that I have an easier time with that.

    I just tried a ton of different ones, to no avail. It makes no sense to me why I've seen others with this same laptop, same video, have no trouble at all with the internal display. I've looked over configs that they posted and I can find nothing significant. They're not even using hot patches like I tried. Unfortunately, those people are no longer active on the forum I saw them post on, or I'd try and get in touch with them to see if they're using the DreamColor display. That's the only variable I can think of that would be different. I'm about to give up and install High Sierra so that I can install the web drivers, and see if that's the magic key. That is one thing I noticed that the others are using, though I'm not sure how they're doing it with Mojave, unless they started with High Sierra and upgraded, and the web drivers remained.

    For that to properly take effect, do I have to also change the BoardID and such, or only the ProductName?
  7. I installed macOS Mojave on an HP Elitebook 8570w with Quadro K2000M video with 1920x1080 "DreamColor" display. Nvidia-only, no Optimus, Intel, etc. I've installed macOS on several laptops over the past 2 years, and this is my first attempt at a system with Nvidia Graphics. Most things are working, except the internal display. I can get it to work if I use nv_disable=1, but that's not optimal of course. External displays work fine, and that's what I'm currently using with it. From using guides from other forums and piecing together configs from others with the same laptop, I'm to the point where I'm injecting some video properties, including the EDID, through a Clover hotpatched ACPI file, but it seems like I'm missing some things, or not understanding some of the settings enough to where I have the correct values. Unfortunately, it's not clear if the other people with the same laptop that claimed to be successful have the same LCD that mine does, and thus I'm not sure if that's the issue. The main settings I'm questioning at the moment in the SSDT file I made are display_cfg and connector-type. The 'connector-type' especially, since the guide I followed to create this SSDT file for the blank screen issue was mainly for desktop systems. I also understand that the display_cfg setting can also determine which video ports are being used and such. I'm also curious whether or not the web drivers when they become available will magically fix this. I'm also considering getting an AMD MXM card that's compatible with this laptop to see if I have the same issue. If anyone out there is skilled with Nvidia and ACPI settings on laptops, I'd appreciate the help. Just let me know what files I need to post.

    Lenovo ThinkPad T420 with UEFI Only

    T420, HighSierra, I upgraded to 16GB of RAM, and I still get the graphics glitches as much as I always did. I can't comment on if it fixed the random lockups as I didn't use it long enough to find out. (I used to use this every day until the lockups became too much of a pain.) I'm mainly curious if this is generally an HD3000 issue. I have a chance to get a T530, which has HD4000 graphics. If I hear that macOS runs better on this machine, I may turn it into a Hackintosh and go with HighSierra or Mojave on it, and put regular Sierra on my T420 and T520 since they were quite stable when they ran it before.

    I get the line flickering and random lines and artifacts through windows that are open sometimes. I've read that it can be from poor quality RAM. I'm not sure what constitutes good vs. poor quality; I've tried switching RAM around between a few different brands, making sure to use the same kind of stick in both slots, but it didn't help. The same RAM works fine in Windows.

    So far so good. The blank screen thing did come back on one boot, but on the next reboot it was fine. I've also had lockups yesterday and today. Both involved Safari, when clicking either the URL box or the tabs. There were times in the past where lockups were always while using Safari. Does anyone else have issues like this- lockups only when using Safari? It kind of sucks- while I'm normally a big fan of the newer Firefox, Safari is zippy as hell when it comes to web apps I use for work. I'm going back to Firefox and see if I can make it through a work day without a lockup.

    Lenovo ThinkPad T420 with UEFI Only

    I did a fresh install tonight, and all is well. I did find the newer zip you posted and used that for the last 2 attempts (the non-fresh and fresh.) Before the fresh install while I was having the no-display issue, I did try the brightness keys. They would indeed adjust the brightness of the back light, but the screen was still displaying black. This was using the Fn+Home/End. I saw the Pause key mentioned somewhere and pressed that as well. Is Pause/SrLck a different brightness control? I also had tried the external DP displays on both the laptop and dock, but one thing I did not try was the VGA outputs. But it's all good; I realized after poking around in Terminal for a bit that I had already backed stuff up to the secondary HDD in the laptop back when I first upgraded to High Sierra and thus didn't really have anything on the main drive to back up. I just wiped it clean and it was no big deal, just have to reinstall a few things. It would have been nice to figure out what the issue was in case it happens again, and future OS upgrades are still going to be scary on this thing, but I'll deal with them when the time comes. I was also previously experiencing the occasional lock ups on both the T420 and T520, so it's good to hear that this has went away? Other than that, the only issues I have with them is with the occasional lines and artifacts in app windows, which I understand can be caused by low quality RAM? I'll have to swap a few sticks around and see what happens. Thanks for the help and advice, not to mention the great guide for these machines!

    Lenovo ThinkPad T420 with UEFI Only

    I used the updated t420 package and was able to boot from the USB. On the T420, I installed over my old installation, and still have the issue of no display. If there was something in my old System folder causing this, wouldn't the installer have wiped out my old System folder? I guess the next step would be to wipe the drive clean and do a completely fresh install. Is there any way to access Finder from the booted installation USB, so that I can save any files I have on the system drive that I might want to keep? I am aware I can copy files around via the command line, but I'd rather not. My HD is an mSATA SSD, and I have no adapters for it, so I can't just pull it out and put it in an external. If not, would a live Linux distro be able to read the macOS drive?

    Lenovo ThinkPad T420 with UEFI Only

    I'm about at my wits end with an issue, and I'm hoping I can get some help. I have a T420 and a T520. I installed Sierra a little over a year ago on both, and overall have never had any major issues. I upgraded both to High Sierra several months ago. The T520 was a success. The T420 failed for whatever reason, and I had to install from USB. This was when 10.13.2 was around. When 10.13.3 came out, the T520 upgraded without issue. The T420, however, did not. It boots, but when the time comes for the login screen, it is a blank screen. Before doing these upgrades, I decided to make my installations as clean as possible, keeping all extra kexts in the Clover EFI, and putting nothing extra in /System/Library/Extensions or /Library/Extensions. On the T420, the OS seems to be loading, since on the blank screen, pressing the Enter key makes the default ding sound. I cannot for the life of me figure out why I'm not getting video. The only alteration I originally made was the edit to the Intel kext to make use of the DVI port on the dock, which worked before. However, I was also not getting video by booting from the USB with a non-altered non-HD config.plist. I do get video in recovery mode, so I also tried putting this unaltered config.plist on the hard drive's EFI partition, with the same results- nothing. I haven't messed with it in a while, and I decided to take another crack at things tonight and was ready to do a completely fresh install on the T420. I tried re-doing the USB installer with the 10.13.4 installer, and for whatever reason, after following the instructions to a T, I cannot make the install partition on the USB bootable now. I erased it with Disk Utility, ran the command line in the guide to copy the installer to the USB, then copied the latest Clover to the EFI partition, but the "Install macOS High Sierra" refuses to appear on the boot screen when I hit F12 and choose the USB for booting. So, you could say I have 2 issues here. I either need help with figuring out why the present install of 10.13.3 won't display video on the T420, or why I cannot get the new installer to show as a bootable option. Some notes that may help: The T420 only has the Intel HD3000 video, no nVidia. Also, it is running the 1.49 whitelisted BIOS, which never gave me a problem with Sierra. My apologies in advance if this is a known issue that has been covered in recent posts.

    I can confirm that it works. I flashed a T420 with it, and it worked fine, whitelist removed and all.
