Try to recreate the installer 1st. If it still fails with the same error, then yes, redownload from the App store.

Hmm, sounds like your installer is corrupted. Try to recreated. If it still persists, then it could be your copy of Yosemite is corrupted.

Awesome! Thanks for confirming that the guide works. I was going to ask for suggestion to make it more clearer.

DSDT.aml

I've tested the E6430 with HD 4000 with resolution 1366x768, bios A12 or below. As mentioned on the guide, set BIOS to default, apply and then set SATA operations to AHCI, that's it. External monitors detected automatically when docked, don't use Fn+F8. Have you tried 'Detect Display' from preferences?

Did you use the bootpack Exx20 rename to Extra and the DSDT.aml from E5420 folder? NullCPUPowermanagement is already included. Boot with -v -f and post your error.

Plug in to an HDMI monitor, see if you get a video output there. No issue with the above DSDT on my E6520 with nvs4200m. Latest Bios A19. I don't have an E6420 with NVS to test the Bios version at the moment.

Grab the latest files here. Port replicator works just fine. I could get only 2 displays working: Tested with single DVI/DP or Enhanced Dock with dual DVI/DP LCD with External monitor through Dvi LCD with External monitor through DP 2 External monitors with DVI 2 External monitors with DP 2 External monitors, 1 with DVI, 1 with DP Note: if you have 1 or 2 setup and wants to move to 3 or 4 or 5, put system to sleep, close the LID, then wake system from the port replicator if you have 3 or 4 or 5 and wants to move to 1 or 2, put system to sleep, open the Lid and then wake up the system LCD with HDMI works too, dock don't have HDMI output, HDMI audio works in this case. HDMI video and DVI/DP video through dock works too and get HDMI audio output thru the HDMI video.

Sleep is a bit slow for this system. Just give it a few minutes until you see the flashing light on the front.

You have to install AppleHDA to /System/Library/Extensions even for Clover.

When you use myHack, it installs all the kexts in /Extra/Extensions to /System/Library/Extension/myHack.kext and bumped up the version # to 1111. This way it'll load before the vanilla version and will survive any OS X updates. Try this GenericUSBXHCI. Place it in /Extra/Extensions overwrite the old version. Run myHack/myfix (Quick). Also don't use the SSDT, SSDT-1, SSDT-2 from my Extra, it's for a different CPU. Create your own following this guide. You'll end up with just 1 SSDT. Remove all the SSDT and replace with the new one. GenericUSBXHCI.kext.zip

DW1501 is not supported, will need to be replaced. for Yosemite guide, see here. Bootpack on post #2 use Exx20 but replace dsdt with E5420

Sorry, you're right, there's no option to disable bluetooth in the BIOS. However I don't encounter the same issue as you. Keyboard and touchpad work just fine. Are you sure the keyboard is not responding? I notice during boot, the bluetooth tries to pair up with a wireless keyboard, you could easily drag it over with the touchpad. Then you could log in.

try disabling the bluetooth in the bios

BOOT 0 ERROR If you are using a 4k HDD you can get boot:0 error, to solve this issue do the following. Reboot system back into Yosemite installer (USB FLASH DRIVE). Launch Disk Utility Unmount the partition you installed Yosemite on Launch Terminal and execute the following command: diskutil list (to find the Disk Identifier of your Yosemite partition (eg. disk0s2) dd if=/usr/standalone/i386/boot1h of=/dev/disk0s2 Exit Terminal Boot Normally Note: if you encounter an error that boot1h is not found when running step 6, download attached and place it in the USB Installer/usr/standalone/i386 and start from step 1 again reference: http://www.macbreaker.com/2012/02/hackintosh-boot0-error.html boot1h.zip

I was using 10.9.2 and then upgraded to 10.9.5 with combo update. Keyboard/touchpad all works fine after wake from sleep. Been doing it all day without an issue. Check your BIOS setting. Set all to default and change only to AHCI and Enable Optimus. Check also that you don't have other PS2 controller installed other than voodoops2Controller from my boot pack in System/Library/Extensions. Another thing to try is delete /System/Library/Extensions/myhack.kext. Then run myHack->my fix (quick). Reboot.

This is in both DSDT.aml for Optimus enabled and disabled. I don't recall losing trackpad or keyboard after sleep for Optimus enabled (HD4000) though. Sleep doesn't work for Optimus disabled (Nvs5200m). I'm not sure where he gotten his DSDT if it doesn't have HPET. Device (HPET) { Name (_HID, EisaId ("PNP0103")) // _HID: Hardware ID Name (_UID, Zero) // _UID: Unique ID Name (BUF0, ResourceTemplate () { IRQNoFlags () {0} IRQNoFlags (_Y10) {8} Memory32Fixed (ReadWrite, 0xFED00000, // Address Base 0x00000400, // Address Length ) })

@wern, My mistake, HDMI audio is not working for E6520/E6420 with nvs4200m. It's working on my E6530 with nvs5200m. I'll continue tweaking to see if I could get it to work. As for the internal display issue, try this DSDT. I had fix the internal display and the battery issue. E6520_nvs4200m.zip

@Millerdry, Which guide and bootpack did you use? The one with Optimus enabled or disabled?

Boot with -v to see where it hangs.

Where did you get this patched file or what did you patch?

Try the version from my signature below Exx20 Touchpad. Tested on ML, Mavericks, and Yosemite. Side scrolling is best, but 2 finger scrolling works too. Thanks to works of Yeahoon, sontrg, npjohnson, bpedman and rehabman.

Sorry, if I wasn't clear. The patched Kernel is only to fix the early reboot loop issue. You still need to patch libCLVMIGILPlugin to fix the preview/quick look crash issue.

Try adding /System/Library/Kernels/kernel to org.chameleon.boot.plist

Yes, HDMI sound works if: Your E6420 only has HD 3000 or Your E6420 has HD3000/NVS4200m, then you have to use NVS4200m. Won't work if Optimus is enabled.
