    macOS Sierra on E6420

    E6420, A23 BIOS, NVS 4200M 512, 128 GB SSD with Vanilla macOS Sierra Retail throws a strange show of checkers once it boots to login screen; Boots fine through -> Clover v2.3k_r3763 -> though it does takes some time to initd6, then ++++++++++++++, -> continues alright till end to load NVDAStartup (Stock or WebDriver-367.15.1.0.05f01) with NVHAL100 -> Shows apple logo with progress bar and then instead of login screen this happens; <key>Graphics</key> <dict> <key>Inject</key> <dict> <key>ATI</key> <false/> <key>Intel</key> <false/> <key>NVidia</key> <true/> </dict> <key>NvidiaSingle</key> <false/> </dict> and <key>SystemParameters</key> <dict> <key>InjectKexts</key> <string>Detect</string> <key>InjectSystemID</key> <true/> <key>NvidiaWeb</key> <true/> </dict> Any ideas???? Appreciate you all.....
  3. I upgraded my E6420 hackintosh to High Sierra and I immediately noticed that I'm no longer able to boot from the secondary drive bay. I usually have my Windows drive attached to the primary SATA port and have one of the drive adapters that lets me install a second hard drive in leu of the optical drive. I had my macOS installed there so I can dual boot between the two. With High Sierra that no longer works. When I try to boot macOS from the secondary port it KP's and is garbled so I can't read what it says. When the drives are switched around macOS boots and recognizes another drive is there but complains that it's having trouble reading it. I can boot Windows from the secondary port just fine so it's not a sudden hardware failure. It sounds like I might need to modify my DSDT but I wouldn't have the slightest clue what I need to do. I know High Sierra is still really new but any ideas?

    Dell Latitude E6420 - Sierra HELP

    i have Dell Latitude E6420 - you can see my hardware in the photos (sorry for the bad english) I tried to install Mac OS Sierra and i got this .. in the BIOS i changed to ACHI. if you will help i will appreciate it Please Helppppp
  5. For what ever reason the brightness control in the System Preferences no longer works. I think it may be related to these two previous issues that I posted about in the past https://osxlatitude.com/index.php?/topic/9131-solved-e6420-monitor-sleep-turn-off-on-boot-fresh-install-of-el-capitan/ https://osxlatitude.com/index.php?/topic/9504-solved-black-screen-on-e6420-sierra-upgrade/ I am using the following DSDT because the one in Jake Lo's Sierra bootpack was not working despite me having updated to the same bios version that the bootpack is meant for, as discussed in the above threads. https://osxlatitude.com/index.php?/topic/9131-solved-e6420-monitor-sleep-turn-off-on-boot-fresh-install-of-el-capitan/?p=61321 But that DSDT was patched back when I was on El Capitan, do I need a new freshly patched DSDT for Sierra? Also why does the LoRes DSDT in the Sierra bootpack not work for me? This has been an issue for me since El Captain, is there something different about my E6420's monitor? It uses the Intel HD 3000 with the max resolution of 1366x768.
  6. I followed this guide step by step, this my clover setup and got stuck on the bios menu, the UEFI doesn't show a boot list to choose the USB drive. Screenshot: http://i.imgur.com/OkdN9Ri.jpg The boot sequence is set to UEFI. But F12 won't show any option to boot via USB, so I added these options on the UEFI Boot sequence: \EFI\BOOT\BOOTX64.EFI And \EFI\CLOVER\CLOVERX64.efi Both return a black screen. What am I doing wrong?
  7. hello. i decided to upgrade my system and I used Jake Lo's guide: https://osxlatitude.com/index.php?/topic/8506-dell-latitude-inspiron-precision-el-capitan-clover-guide/&do=findComment&comment=54632 allmost everything works fine when using USB for boot, but when I try to boot from disk, i loose USB-ports. So what is wrong? this is first time using Clover so it's quite confusing how to set up the machine, installer and where to install and copy things. f.e. any help is appreciated stupid questions will follow, maybe some other newbie as me have same questions... so here we go: 1 How do i have to set up the settings etc to get everything work from HDD? for Latitude E6420 Nvs4200M i used Legacy options - (in the guite: For Exx20 (SandyBridge models), use Legacy - GUID Scheme. Not UEFI) do I have to make USB installer using Legacy or UEFI Boot Sequence in BIOS? or it does not make a difference? When installing Clover (version Clover_v2.3k_r3320) into the USB installer I used only: Install Clover in the ESP Bootloader/Install boot0af in MBR CloverEFI/CloverEFI 64-bits SATA Preference panel is it right? or i need to install RC scripts also? weird, when booting it shows newer version of Clover than 3320. ??? 2. I Used Generic EFI folder (EFI.zip) + E6x20 NVS.zip (downloaded from the same page). It took a while figuring out where to put file in E6x20 NVS.zip. At last i checked original EFI folder before replacing EFI folder for new one - it helped to figure out things a little bit. Still questions: where do i have to put the kexts in folder Other. Leave them as they are (Other folder) or make a 10.11 folder in the USB stick’s EFI partition? /Volumes/EFI/EFI/CLOVER/kexts/Others ? or /Volumes/EFI/EFI/CLOVER/kexts/10.11 ? 3. When installing El Capitan into the harddrive same questions raised: ido i have to install sing Legacy or UEFI Boot Sequence in BIOS? or it does not make a difference? installing Clover into the hard drive i used only: Install Clover in the ESP Bootloader/Install boot0af in MBR CloverEFI/CloverEFI 64-bits SATA Preference panel is it right? or i need to install RC scripts option also? 4. When generating ssdt.aml with ssdtPRGen.sh where do i have copy the ssdt.dsl ? 5. In /Volumes/EFI/EFI/CLOVER/ACPI/patched is dsdt.aml file. how do i generate a new one? or it’s not a must do thing? 6. Where do i have to put config.plist? I modified the one which is on EFI partition (in CLOVER folder). 7. when copying kexts to hard drive: where do i have to put the kexts in folder Other. Leave them as they are (Other folder) or make a 10.11 folder in the USB stick’s EFI partition? P.S. it seems that one of the generators needs internet connection to work properly! 8. When using EFI Mounter app do i have to unmount the volumes before proceeding? anyway, thank you Jake Lo and others for the great installer guides and tips! any help is appreciated. _____ Intel Core i5 2520M (integrated Intel HD Graphics 3000) 8 Gb RAM NVIDIA NVS 4200M HiRes 1600x900 LCD WIFI - Qualcomm Atheros AR3011 (not working yet, using WIFI stick) bios A22 I think it is Sandy bridge version.

    E6420 : HDMI Woes

    So I have an E6420 no optimus, low-res (specs in signature L01), and everything is working great...until I plug in external monitor to the HDMI port....then all hell breaks loose. after plugging in hdmi -- native laptop monitor is underscanned. I change the display preferences to turn off mirroring / use hdmi monitor as extra display, restoring built-in lcd resolution. Upon reboot, built-in lcd is black and hdmi display is the only detected display. Shutdown, unplug hdmi cable, reboot and built-in lcd is black screen ... only way i can get a display is by plugging in hdmi cable to external monitor. I caught a screenshot that sort of highlights the issue during same session of hot-plugging the hdmi cable...notice that the resolution is 1920x1080 for the built-in display in system info but of course it can only output 1366x768 E6420-L01__CFG.zip I tried the sierra bootpack from jake's infamous guide (esp since it was patched dsdt for a23 bios) but that didn't even get me to the install screen...I am instead using a LoRes DSDT from others, not sure the exact source, but somewhere on this site. Anyways, I posted my efi directory which contains everything, config.plist / dsdt.aml and native/clean acpi dumps...lemme know if this issue has been solved or how I can go about troubleshooting, thank you!!!

    [SOLVED] Black screen on e6420 Sierra upgrade

    Hi, I recently tried to upgrade my El Captain installation to Sierra after noticing that Jake Lo had updated his guide to include an e6420 bootpack for Sierra. From what I can tell things are working so far except for one major thing. The screen does not work, it’s a black screen and I can only use the laptop via the hdmi out. I do not think this is a bios issue this time, because I saw that the bootpack was for bios version a23, so I updated my bios to a23 beforehand. My monitor’s resolution is 1366x768 and I am using the DSDT-LoRes from the new bootpack, but it would appear that the resolution that is being output, at least via hdmi, is 1360x768, maybe this is the reason why I am getting a black screen? I’ve attached a picture of my tv saying that the resolution is 1360x768, just to show where I got that number from. Any help would be greatly appreciated.

    [SOLVED] E6420 and osx sierra

    Hi everyone! Now I'm trying to arrange dell e6420 with sierra. i've installed the osx sierra (with -x -v flags in clover - other variant didn't start the installation). Now i've got some troubles - i've installed Clover to ssd partition 'n made the default boot volume. Clover starts, and when i use -v flag i've got the fault, system does'n boot - picture attached. Also i've attached the clover folder (just in case). Nevertheless i can boot from usb stick. In this case keyboard and integrate mouse aren't work, sound is missed, wifi is working (i've changed the wifi card to the right one) and there is some artifacts with screen. Will someone help me out? will be very appriciate. CLOVER.zip
  11. Hello All, first of thanks to all here at OSXLATITUDE. Thanks to you im now on my third Hackintosh. They have given me lots of joy I used the guide posted here by Jake Lo and was able to get EL CAPITAN 10.11.6 running on my E6420. it runs very smooth and fast and i have triple boot option with Clover. (Linux, OSX, Windows)... I know windows... but i need it for work. issue I'm having is that I'm experiencing freezes on OSX but ONLY when minimizing a window. right now i have only seen it while minimizing Safari, so i have been using chrome instead, but every so often im now getting it on chrome as well. when i hit minimize, the windows starts mimizing and freezes half way through, and then it goes all the way down. (see attached picture) I wonder if anyone can shed some light on this issue. is there a log of some sort i can share to try and understand this issue ? I wonder if it has anything to do with the triple boot and that i had to go to linux and load a program to keep all 3 partitions in sync since the drive became GPT/MBR Hybrid. as per the guide for the triple boot i had to load "gptsync", which makes the partitions stay in sync. I only mention this because thats an old guide (2010) and while everything works it may be outdated and maybe causing the issue. any thoughts ? Specs: Dell E6420 8GB RAM 525 GB Crucial SSD intel i7 2.8Ghz 1600x900 Display Using the bootpack EFI from the guide posted here.
  12. Hello I've decided to try my hand at installing OS X on my E6420 for the 2nd time. I just installed El Capitan 10.11.5 using Jake Lo's guide. Everything appears to be fully functional except for one thing, my laptop monitor will always turn off during boot. The system is running fine in the background but my monitor just turns off for whatever reason. Unplugging and repluging the charger is my current work around. This works when have access to a wall outlet, but otherwise I am stuck with the monitor off. I am using the e6420 bootpack with the DSDT-LowRes.aml as my display's resolution is 1366x768. Also I do not have optimus on my laptop.

    macOS Sierra on E6420 HD3000

    Upgraded my E6420 to Sierra. Got my BCM94352 working after some difficulties. For some reason Clover's FakeID is not working and had to switch to the FakeID kexts. One of the problems I ran into while upgrading is that the VoodooPS2Controller.kext needed to be updated. Was getting a panic on it. That resulted in the touchpad ceasing to function. That and I need to figure out how to get the audio working again. Other than the trackpad and audio I have a functioning system. Fortunately Bluetooth never stopped working and I have a Magic Mouse until I can get the trackpad working again.

    E6420 update to 10.11.4 El Capitan

    I just ran into the problem after updating my Hackintosh E6420 from 10.11.3 to 10.11.4. I updated by the dmg file from Apple server today. I am using Clover legacy bootloader. First, there is no audio after updated. Second, I can't boot into El Capitan without using boot parameters -v -cpus=1. If I boot without these parameters, there will be kernel panic and restart automatically. Have anyone experienced the same problem? Let's discuss.
  16. I recently installed Capitan on my E6420 which has a NVS 4200m with 512MB using the E6420 bootpack and DSDT from this guide . Everything seems to be ok accept my NVS 4200M shows that its using only 256MB instead of 512MB. Can anyone help me with this?

    E6420 El Capitan booting Clover issue

    Hello! I have installed El Capitan in my E6420 following Jake Lo's "Dell Latitude / Inspiron El Capitan Clover Guide". (used E6220 bootpack). I still have to fine-tune installation but I have one doubt regarding Clover boot: Why I can only boot legacy? Even enabling UEFI in BIOS I can´t see UEFI boot entry after pressing F12.... My plans are to dual boot Windows 10, so partition must be GPT pure... Thx

    Newb Install Help - E6420 El Capitan

    First off, thanks for providing this amazing resource ladies and gentlemen. It's much appreciated! I'm a long time Linux user and am taking my first step into installing OS X onto older hardware. I've run into some difficulty and am hoping for some pointers. I have a Dell E6420, A21 BIOS, i5-2540M CPU, 4GB RAM, Intel HD3000 graphics, 1600x900 Resolution, 250GB SSD. I followed the wonderful instructions in the following post using the E6220 boot pack: https://osxlatitude.com/index.php?/topic/8506-dell-latitude-inspiron-el-capitan-clover-guide/ However, I get stuck at one of two places: 1) With the stock + E6220 boot pack I get a kernel panic with message "pmLock: waited too long". 2) If I add NullCPUPM kext then I get a black screen that slowly turns all white. I did try to add DualLink into the Clover config. I've been trying different things from the forums, but with less success. I still have yet to see an installer screen. I do appreciate whatever time you can spare to help me get up to speed. I apologize If I'm missing something obvious, but this is all pretty new to me.
  19. First of all here are my system specs: Dell Latitude e6420 Intel Core i7 2720QM 16 GB RAM NVS 4200m I had mavericks installed with everything working using chameleon, the dsdt from here http://www.insanelymac.com/forum/files/file/342-latitude-e6420-nvs-4200-dsdtaml/ kexts from here https://osxlatitude.com/index.php?/topic/6192-guide-mavericks-on-dell-latitude-e6420/ and an ssdt from here https://osxlatitude.com/index.php?/topic/5943-dell-latitude-e6520-e6420-with-optimus-enabled-mavericks/ I had to switch to clover to do the upgrade, and it installed fine. The issue is that now it kernel panics when I try to boot it. Here is a picture I managed to grab before it turned off: Does anyone know what is wrong?

  21. New to this website but pretty much here for the same reasons as everyone else. I want to turn my Dell Latitude E6420 into a Hackintosh but I am having issue installing OS X Yosemite from a bootable USB. I get stuck on a white screen and when I try to access the BIOS menu to unlock and enable legacy boot I am asked for an Administrative Password. Did anyone with a E6420 have this same issue as well? If so what did you have to do?
  22. This is for the model E6420 with the Intel 3000 Graphics Card, could someone who uses the Nvidia version please post their findings on it. Thank you all.

  24. Hey All, Its been a while since I've been here, but I got OS X Yosemite Final/GM 3/ PB 4 running on the E6420 via the following means. Credits: @Jake Lo - DSDT patches for HDMI audio, Most of the boot pack actually. XD @Pokenguyen - teaching me clover, giving me a WIP guide that this guide is partially based on, A lot of help along the way, config.plist and many other things, the reason clover is working on the e6420 (: @Stork - Starting the research thread and figuring out the original stuff back on Lion (: @RehabMan @BpedMan @sontrg @Yeahoon and myself - Work on the VoodooPS2 Project for ALPS, its come a long way and is still in development here: https://osxlatitude.com/index.php?/topic/2545-new-touchpad-driver-for-e6520-alps/ @All - Debuging and helping out, without all of us, we wouldn’t be this far Myself - Patching a new version of SNBGraphicsFB for VGA/HDMI using telnax's method, writing the guide, patching the new RTC, editing VoodooHDA. None of the Wifi cards that shipped with our model are OS X compatible. Please order the one listed in my signature and replace using the guide created by Dell here. Other cards work, such as the one listed in Jake Lo's signature (He is all over the site, just look around). To Make Bootable Media (Pulled from here and here) 1. Download Install OS X Yosemite.app (Any version will do, i.e. DP1, DP2, DP3, DP4, DP5, DP6, DP7​ (preferred), etc.) 2. Right click on the installer > show package contents 3. Navigate to Contents/Shared Support and double click on the InstallESD.dmg, the .dmg should now mount and appear on your desktop 5. In the terminal issue the following command: open "/Volumes/OS X Install ESD/BaseSystem.dmg" 6. Now, open disk utility and restore your usb drive, NOT the drive, but the volume contained on the drive with the mounted "BaseSystem" NOT the .dmg. 7. Rename your usb drive to Yosemite. (not the dmg) You can tell which drive is the USB from the size. 8. Issue the following commands in terminal: cp "/Volumes/OS X Install ESD/BaseSystem.dmg" /Volumes/Yosemite/ cp -a "/Volumes/OS X Install ESD/BaseSystem.chunklist" /Volumes/Yosemite/ rm /Volumes/Yosemite/System/Installation/Packages cp -a /Volumes/OS\ X\ Install\ ESD/Packages /Volumes/Yosemite/System/Installation/Packages 9. The last command may take some time, go get some food 10. Now install Clover to your USB drive. (download it from here) Selecting the options shown in the linked image: http://imgur.com/if2O3hQ 11. Unzip the flies provided in E6420Yosemite.zip 12. Move all the files in the unzipped /Clover folder to /EFI/EFI/Clover/, make sure to choose to MERGE these folders. Installing 1. Shut Down 2. Enter BIOS via tapping F2 during boot 3. Change SATA Operation to AHCI (Leave the Booting mode on Legacy! UEFI is not support/does not work.) 4. Click Save and reboot 5. Hit F12 as computer boots, select USB Drive 6. Select boot "Mac OS X from Yosemite" 7. If given a keyboard error, spam the spacebar 8. Use disk utility in the "Utilities" drop down menu to format your HDD to "Mac OS Extended Journaled" and make sure to click options and select GUID partition table, proceed with formatting 9. Follow installers prompts to install Post Install If running anything other than Yosemite Final/GM 3/PB 4 (You can update via the Mac App Store or via the delta installers found here. After installing these click restart, you will most likely end up having to hard reset (hold power button), then boot from USB, but this time select "Boot OS X from "Your Drive Name". 10.10.1 is SAFE to update. No changes at all for this release, just Mac App Store Update. 10.10.2 (14C68m) Beta is also safe, and graphical glitches actually went away for me after this update, wouldn't recommend the Beta to the Public of course though. For UEFI Mode: Although it works, it is somewhat buggy, because Dell left UEFI on our model Half-working. I really don't recommend this though. If you really want to use it, go ahead and select UEFI checkbook in the Clover installer and add the boot entry to your UEFI BIOS Selection "/EFI/CLOVER/CLOVERX64.efi" and boot it. For Legacy Mode: 1. Download and run the Clover installer once again from here, select the following things show in this image in the installer: http://imgur.com/ipc5mTq PLEASE also check the "Install Clover Preference Pane" checkbox 2. Download and install Clover Configurator from here 3. Open Clover Configurator (From now on referred to as "CC") and go to the EFI tab, click mount and enter your password. 4. Re-download the attached E6420Yosemite.zip and extract 5. Move the folder /Clover from the unzipped to your hard drives /EFI/EFI/Clover/ location, make sure to choose to MERGE these folders 6. Reboot 7. For Multitouch Gestures go to System Preferences ==> Keyboard ==> Shortcuts ==> Mission Control ==> Now chose the action you want (i.e. show dashboard) and click in the shortcut box, and do the gesture you want (it will show some weird keys, ignore it). 8. For Proper Keyboard, go to System Preferences ==> Keyboard ==> Modifier Keys ==> change Command Key to Option Key, and Option key to Command Key. 9. Run the script "Remove Problematic Extensions.sh" script (it will create a nice shortcut to /System/Library/Extensions/ called /s/l/e, it will also remove problematic kexts. To run this, extract the file, then right click the extracted file and choose "Open With" change from "Recommended Applications" to "All Applications" and select terminal, then enter your password. 10. Reboot Working Wifi (Athertos AR9281, recognized as native Airport Extreme oob, if you want one, the ebay auction is linked in my signature) Keyboard USB Bluetooth App Store and iMessage Screen Brightness Battery Percentage - Broken from DP5 onward. Display and Screen Resolution Audio buttons and audio control HDMI + Audio (Auto Detection works!) QE/CI Network Switch Docking Port eSata Free Fall Data Smart Card Reader Express Card Reader Most Multitouch Gestures (3 and 4 fingers work) Webcam VGA output (No Auto-detection) Find my Mac and iCloud Edit 1: Sleep and Deep Sleep!!! Edit 2: Use updated VoodooHDA for Volume Control! Edit 3: Hibernate! Use new DSDT/SSDT, Just invoke it via one of the thousands of scripts out there that hibernate your mac. Edit 4: UEFI Mode! Works via adding boot entry manually, and only works after most recent Clover Update. Partially Working SD Card - Voodoo SDHC is buggy, only works sometimes on our model and breaks sleep, still want it? Find it in the folder labeled VoodooSDHC and install via kext wizard, then reboot. Battery Percentage - No known kext works. System still reports battery to the low battery (>10%) to the blinking yellow light on the laptop. We will have to wait for AppleSmartBatteryManager.kext to be updated. Just keep trying it at every new release. The DSDT is patched for it when the kext works with 10.10. Not Working Nothing!!!
