You would not need to re-install the OS from scratch... Just the bootloader.

You gotta love Chameleon!

Erm... your SysProfiler output is from Mavericks... Not really what I was looking for. There is no sign of your DW1550 built-in BT module in your SysProfiler so it's clearly not registering as a USB device. I also note that you don't appear to use the latest optimised Mavericks' pack available here. Can you please post the saved SysProfiler output taken from El Capitan or Sierra with the DW1550 installed and the CSR dongle taken off? Whilst you're at it, also post: 1) your complete zipped /Extra folder (you're using Enoch, right?) without the Themes subfolder to minimise size 2) a saved IOReg output from IORegistryExplorer (both from El Capitan or Sierra) If you have an internal Bluetooth module such as a DW350 or DW360, disable the Internal Bluetooth in BIOS; otherwise, it'll take precedence... Your USB ports & devices should look like this under Sierra: As a test, I installed a spare Apple BCM94360CD (Combo Wifi 802.11ac + BT 4.0 card) in the WWAN slot of my D630. As expected, the Bluetooth module of the card is properly detected and listed as an internal USB device:

Yes, you can run El Capitan and/or Sierra with CsrActiveConfig set to 3. That's what I use on all my Hacks, E6230 included. Reboot without cache when you 1st call on the revised value and rebuild your cache thereafter.

Can you explain the details of what you did regarding Rehabman's kexts? The process works perfectly for a DW380 (Broadcom BCM20702 chipset) so I don't see why it would be different on a DW1550 which is clearly mentioned in Rehabman's list of tested & supported devices. Please post a zipped SysProfiler saved output.

I don't follow what you do at all, but you're obviously not doing this right. You need to follow the guide step by step and you'll get there, unless you have a duff USB key of course...

The reboot is probably due to the unsupported CPU model. I guess you'd have to try and fake a different CPU id. I don't think this specific Haswell Intel HD graphics GPU is supported either... In other words, don't hold your breath; you may have to upgrade your CPU to a supported Core "i" model to be able to install and run OS X.

The Intel GMA4500 GPU fitted to the E6x00 family is unsupported, so you can forget about hackintoshing them indeed. For the E6500 with nVidia GPU, make sure to use MacBookPro7,1 profile. You can look at my D630 nVidia Sierra guide for pointers. You may reuse many items from the pack I posted (obviously DSDT + some kexts will need to be replaced). Look up existing E6x00 nVidia pack to retrieve the hardware specific kexts (like LAN driver for instance).

The latest OS X version you can run on a D620 with GMA950 is Lion 10.7.5. From Mountain Lion 10.8, Apple dropped support for the obsolete Intel GMA GPU. For Lion, we advocate you build a USB installer using myHack utility. If you have no access to a Mac or an existing Hack, try using a virtual machine. You can use the Lion bootpack available here. Please note that the D620 is fitted with Intel ICH7-M I/O controlller so disk mode is limited to IDE, not AHCI and SATA-II (3Gb/s) speed. Your SSD will therefore only appear like a traditional HDD and you'll have no support for Trim. Still, it'll run faster than a good old HDD.

Re-nable IDA.

There is a dedicated section about multi-OS booting. https://osxlatitude.com/index.php?/forum/172-multiple-boot/

If you want an easy Sierra installation on your E6220, I invite you to follow this guide.

Keyboard backlight is controlled through BIOS settings, not Operating System.

https://github.com/Piker-Alpha/ssdtPRGen.sh Read then follow the instructions.

Try to put the laptop to sleep then wake it. Headphones should then work. Remember to re-patch your AppleHDA binary file if you update Sierra, though reverting to v278.52 of my posted pack should work too. The patch is as follows: Find: 8419B411 Replace by: 00000000 Find: 8A19D411 Replace by: 00000000 Find: 8B19D411 Replace by: DF761D11 There are 2 x instances each time. I've not needed CodecCommander or EPADFix but you may add it if you find that the headphone output does not always work until your put laptop to sleep then wake it.

That command is only supported from Yosemite 10.10. On earlier versions, use sudo kextcache -system-prelinked-kernel (whih is also supported on later versions).

Ok, I know it's been several years but let's clarify something immediately. We used and advocated Apek Protector Suite v2.0 on the old Latitude D Series up to Mac OS X Snow Leopard 10.6.8. From Lion onwards, the software no longer ran and we used to advocate Authentec TrueSuite v5.5.0.5. That software certainly runs in Lion and ML, after which I 'm pretty sure development stopped. I can't remember testing it in Mavericks or beyond since I only have a biometric reader on my D430 and the buck stopped at Lion 10.7.5 (ML with MLPF). http://web.archive.org/web/20130616232312/http://support.authentec.com/Downloads/Mac/TrueSuite.aspx#LiveTabsContent39073

By their very nature, USB-based Bluetooth devices will never be listed in the lspci output. You'll only see them in the USB section of your SysProfiler. Try Rehabman's bluetooth firmware fixes: https://github.com/RehabMan/OS-X-BrcmPatchRAM

The software only seem to support the Upek biometric readers of the Dell D Series (I have it running on my old D430). It does not work for readers fitted to more recent Dell laptops such as the E Series for instance. It's a totally different piece of hardware. I should have a copy of the software somewhere. If it fits as a post attachment, I'll upload it. Obviously this Upek application only ran on laptops fitted with Upek's hardware accessory (older Dell, Lenovo, Sony, Acer and Asus models). I understand Upek was subsequently acquired by Apple and product support ceased.

Last time we looked at the specs, they were pretty much alike any IvyBridge E6x30.

The mini PCIe slots of the Dx30 do operate in combo PCIe/USB mode. Oherwise the WWAN modules would never work and they can be use in any slot. EDIT: WRONG: Ok on the D430 (both slots) but not on the D630 in which only the WWAN slot is combo PCIe/USB; the WLAN slot is PCIe only.

Why do you use that kext?

Never assume that a 3rd party component such as combo wireless/bluetooth card will work OOB. 1st identify the Bluetooth chip used on the DW1550 then refer to the Wireless and Bluetooth section of the forum. You may also want to read the existing literature on your Bluetooth matter. You also confuse USB ports and USB devices. The USBInjector kext only serves one purpose: get the built-in USB ports to be recognized and work, not the connected USB devices...

You can refer to my D630 guide if you need anything. I use a tuned USBInjector kext that matches the D630 USB2.0 ports arrangement under the chosen SMBIOS profile. Watch because I use a different SMBIOS profile between OS X versions up to EC (MBP5,1) and macOS Sierra (MBP7,1). I can't guarantee that the USBInjector kext I use for the D630 will also apply directly to the D830, but you can use IORegistryExplorer to identify all your ports and adjust the kext Info.plist file as needed. The packs also include FakeSMC kext tuned for GPU throttling (AGPM patch) and native CPU SpeedStepping. SSD/HDD speed is limited to SATA II performance, i.e. 3Gb/s max, not 6Gb/s; nothing you can do about it, that's the chipset specs...

Cache did not rebuilt properly: Error 77... Re-type the touch + kextcache commands.
