Could you attach the kext you used for the audio? I cannot seem to get any of them working.

Thanks

Note that contrary to the advice in post #1, patched AppleHDA must be installed to /S/L/E.

I'm sorry for the basic question, but where am I supposed to place the config_4600_4400_4200.plist file?

Thank RehabMan. I downloaded your raw config_HD4600_4400_4200.plist renamed it to config.plist and added to Clover, when I restart clover no longer sees any of the volumes.

When I replace with previous config file, laptop starts fine (though Clover Utility still comes up with error "no config.plist found").

You forgot HFSPlus.efi. Always read carefully.

I am going to install El Capitan on my Lenovo G50-70 (i5/8Gb Ram) and before starting I'd like to know:
  • is VGA out mirroring and/or extended desktop working?
    If it isn't working but someone is already looking for a solution I am available for help and testing, my actual lapintosh (hp630) doesn't have a usable VGA output and I'd really like to have it on my next one :)
  • I will use a new 1Tb hdd, any particular advice about partition strategy?
    I won't install Windows but maybe I'll install Linux to have a dualboot system, if I go for a single big partition will I be able to resize it easily?

thanks for your help

P.S. I already created the USB installer (Multibeast, MaciAsl, patches repo and audio kext ready on its root) and it boots flawlessly, I just have to switch the actual hdd with the new one received today and install
P.P.S I ordered a DW1560 (BCM94352Z) NGFF card as replacement

The VGA port is not supported (Apple computers don't have VGA). Use HDMI/DP (whichever the laptop has).
