Sierra does indeed work perfectly on the E6220. I'm overdue for the guide but it's basically more or less the same as for El Capitan and you can re-use the same pack meantime (I've just updated it with Dr Hurt's VoodooPS2Controller Release 4).

You install Enoch with the default settings, that's why there is no further details on its installation. The bootpack will then add all necessary options. The KP is due to the VoodooPS2Controller provided in my pack, I need to replace it with Dr Hurt's Release 4. Grab it from here and you should then be able to boot 10.11.6 Ok. I'll update the pack. My apologies for not doing this sooner.

Sierra runs with the same patches/adjustments as El Capitan...

Sounds like you're talking about a OS X disk/partition + a Win disk/partition on the same PC. If you cannot get Transmit to work properly, why don't you create a 3rd small partition, formatted FAT on which you can copy files to/from Win and OS X? That certainly works, I can vouch for it.

Looking at the extracted DSDT, it appears the PCI root is set to 0: Scope (_SB) { Device (PCI0) { [...] Name (_UID, 0x00) // _UID: Unique ID It's the _UID value of device PCI0. From OS X, the PCI root value can also be checked through the following Terminal command: ioreg -l | grep -15 "AppleACPIPCI\ " | grep UID ` You can refer to this old thread for details: https://osxlatitude.com/index.php?/topic/2061-dell-precision-470-670-workstation-snow-leopardlionmountain-lionmavericksyosemite/&do=findComment&comment=32511 https://osxlatitude.com/index.php?/topic/2061-dell-precision-470-670-workstation-snow-leopardlionmountain-lionmavericksyosemite/&do=findComment&comment=32511

It'll be worth checking what PCI root value Dell set on this workstation. Dell had a habit of setting it to 4 on its high end PCs and workstations. It was therefore necessary to set PCI root to 4 as a bootloader option to be able to successfully boot OS X. Thereafter, the DSDT could be patched to change the PCI root to 0 (i.e. default bootloader value).

Indeed, the E6x20 normally only runs OS X with BIOS in legacy mode.

There are existing threads on keyboard remapping. https://osxlatitude.com/index.php?/forum/102-keyboard-trackpadtouchpad/

You should use MBP9,2 or MBA5,2 SMBIOS on your IvyBridge E6430.

Forget about 802.11ac cards under SL or Lion; OS X only supports this from ML 10.8.4, or 10.8.5 i.e. unreachable territories for the D630 GMA X3100. In addition, please note that the D630 only takes full-size mini-PCIe cards so you would need to add an adapter plate if you want to install a half-size wireless card. I would advise you to consider a full-size 802.11n Broadcom and/or Atheros card that'll work OOB. I can recommend Atheros AR5B91 (2.4GHz) or AR5BXB92 (2.4+5GHz). On the Broadcom side, you have the DW1505.

You're getting compilation error for the _OFF and _ON methods you've added because they're not declared in the DSDT but in one of the SSDTs. As such, you must declare these functions as External functions at the very top of your DSDT; you'll see similar code lines for other functions. Just copy/paste existing external declarations and adjust to _OFF/_ON functions. Should be something like: External (_SB.PCI0.PEG0.VID._OFF, MethodObj) External (_SB.PCI0.PEG0.VID._ON, MethodObj) You'll find guidance and samples on this matter here.

I would modify 2 things in your Clover config.plist: in Graphics tab, I'd select option "inject nVidia" in SMBIOS tab, I'd opt for iMac16,1 (Broadwell) rather than MacPro6,1 (IvyBridge) If you can, try and press F4 at Clover main menu to extract your raw BIOS tables and get them saved to CLOVER/ACPI/origin folder of EFI partition. You can then post us a zip archive of your DSDT and SSDTs.

Many Dell workstations are configured with a PCI root set to 4. With default PCI root set at 0, bootloaders often can't initialise graphics cards properly until the value of 4 is specified.

Recompile the table and save the .aml file to ACPI/patched folder of your EFI folder. Patched AppleHDA must be placed in /S/L/E where it replaces the vanilla kext. Permissions must be repaired and cache rebuilt thereafter. The kext will not load from anywhere else.

There should not be much really. Look for builds of similar specs or post a zipped copy of the EFI folder of your EFI partition and we'll have a look.

You'll probably have to make up your own boot pack. All you need to begin with is the FakeSMC kext (it's mandatory). Thereafter, you look for drivers that handle your hardware elements (LAN, audio, wireless, etc.). You're also going to have to configure Clover according to your system. Your Workstation is based on a Broadwell platform.

I don't believe BCM5722D LAN kext applies to the E Series... Kexts placed in the EFI/CLOVER folder are injected at startup. Once you're happy you've got the right kexts, move them to /L/E from where they can be cached, which improves startup time.

Your DSDT patch is fine as it is; nothing to change. Do the rest.

Identify SD card reader in IOReg through IOregistryExplorer app (or any equivalent). Patch the DSDT device under which the SD card reader registers Remove all instances of VoodooSDHC kext (in SLE and/or LE and/or EFI/CLOVER/kexts folder of EFI partition) Rebuild cache from Terminal using: touch -f /S*/L*/E* touch -f /L*/E* sudo kextcache -Boot -U / If you get an error 77, repeat the commands.

You can create a Sierra USB installer using the usual manual process (same as for Yosemite or El Capitan), then install the bootloader (Clover or Enoch) and the required bootpack. You can reuse your existing Yosemite pack (I understand you currently run that). For an Enoch based installation with BIOS in legacy mode, you can follow a similar process as described here, excluding the computer's specific pack of course. I would recommend you create a separate partition and retain Yosemite for the time being.

Spidey123, the patch certainly looks good now so, if your SD card reader is indeed under Device (RP06), you should have a fully functional reader. If not, do as Jake suggests right above.

Upload it here. I trust you did not just copy/paste Jake's patch into your DSDT. It's meant to be saved into a text file then loaded as a patch to apply.

Please try and do your homework...

I cannot speak for Clover, but nVidia GeForce GT610 certainly is support OOB under Chameleon/Enoch with simple boot option GraphicsEnabler=Yes. Maybe you can post a zipped copy of your EFI folder for us to check things out. NB: GT610 is unsupported under Sierra for the moment.

Maybe you patched your DSDT incorrectly. If done correctly, the patch is 100% successful on the E6x20 and E6x30 series. You most also remove the VoodooSDHC kext and rebuild your cache afterwards. NB: the DSDT patch does not change the PCI ids at all; it merely injects compatibility with Apple's default SD card reader. That's all.
