seems someone is able to install Mavericks and Yosemite here.

Follow the post installation instruction. Did you see the Clover loader and it won't boot or you don't see Clover loader at all? Please be more specific...

It might be an internal USB issue. Check to see if your bluetooth shows up under USB in about this mac.

You shouldn't lose audio by changing smbios. Perhaps you changed something in the DSDT?

You should generate a new SSDT after you changed the smbios.

No, you should generate it after you have changed your SMBIOS to MBP8,2

In order to use UEFI, you must format the EFI partition to Fat16. See here.

Download this. Launch it, then click file and select save. Save to Desktop, compress it and upload it here using 'More Reply Options'.

There's only 1 error you have to fix, Warnings and Remarks can be ignored. To fix your error 'Invalid leading asterisk, run this patch. Place this in the 'Patch Text' window and hit apply #Maintained by: RehabMan for: Laptop Patches#fix_HID_pnp.txt # To fix Name(_HID, "*pnpXXXX") and Name(_HID, "pnpXXXX") into_all all code_regex (Name\s+\(_HID,\s+\")\*pnp(.*\") replaceall_matched begin %1PNP%2 end; into_all all code_regex (Name\s+\(_HID,\s+\")pnp(.*\") replaceall_matched begin %1PNP%2 end;

Try booting from the USB 2.0 port on the left

Make sure secure boot is disabled too.

Did you format the USB Installer with GUID and install Clover according to this specs? Then adding the bootpack from post #2. Note Bootpack is a combo of the Generic_EFI + E7440 = EFI Install for UEFI booting only Install Clover in the ESP Drivers64UEFI\OsxAptioFixDrv-64

Is your USB installer with Clover? Chameleon does not support UEFI. How is your Installer configured?

Install this for Bluetooth and this for Wireless. Kexts you'll need from the downloads: FakePCIID_BCM94352Z_as_BCM94360CS2 FakePCIID BrcmPatchRAM2 and BrcmFirmwareRepo, or BrcmFirmwareData if needed.

You still need to upload IOReg exported from your system.

Upload your working Clover folder, I'll add or fix it for you.

Please specify the system's full specs. Are you looking for a Chameleon or Clover guide? I have a Yosemite Chameleon guide but can easily be updated to El Capitan. Just need to use the Enoch branch of Chameleon and disable SIP. Just use our search engine. You'll a bunch of El Capitan with Chameleon guide, just replace the bootpack with M6800.

I'm not sure Quadro K2100M is supported. Can it be disabled in the BIOS? Does system have HD 4600?

Try this config.plist.zip

For QE/CI, I don't think you need inject EDID, so uncheck it. The AppleIntelFramebufferAzul patches, you have way too many and I don't know if you need them all. Enable just a few to test at a time. Do you have FakePCIID_Intel_HD_Graphics and FakePCIID installed? You'll need a DSDT to disable the Nvidia card too to save battery life.

Use Legacy as declared in the guide. Note1: For Exx20 (SandyBridge models), use Legacy - GUID Scheme. Not UEFI Install Clover with the following settings in 1: Prepare Bootable USB Drive step 26 above: Install Clover in the ESP Bootloader/Install boot0af in MBR CloverEFI/CloverEFI 64-bits SATA

I know this sounds strange, but changing the SMBIOS to MBP10,1 or MBA6,2 will get you up and running.

Here 1.60.5 ACPIBatteryManager.kext.zip

Replace DSDT with this one for SDcard reader

There's an old guide here that might be able to get you started. The Intel Wireless card will need to be replace with a compatible card though.
