Inspiron 3148 El Capitan/Yosemite


Recommended Posts

i want to install El capitan or Yosemite on my laptop.

Not sure which would perform better;sleep usb 3.0, hdmi ETC.

Cannot find anything on this to guide, was only able to boot with chameleon and mavericks.

I have installed clover builds on HP laptop, optiplex 760/780, vostro 220

Want this thread to help others with this laptop.


Ready for a clover build, I can build the USB installer but doesn't boot to installer, instant reboots.


Laptop specs:

Intel i3-4010U 1.7GHz dual-core Haswell ULV CPU (no Turbo boost)

Intel HD 4400 Graphics
DW1560 wireless
Can provide any other info, thanks in advance!

Instant reboot may be due for missing KernelPm CPU option in Clover config; it's required to handle kernel-based CPU Power Management for Haswell CPUs (AsusAICPUPM is for Sandy/Ivy Bridge platforms).


You may want to add the following hardware details to your specs:

  • LAN card model
  • Audio codec
  • SD card reader model
  • Bluetooth model
  • etc.

I was able to install Yosemite with clover method.

  • Touchscreen
  • Webcam
  • Closing lid turns off display
  • Battery percentage
  • Usb/usb 3.0
  • DW1560 wifi

---Not working---

  • Graphics, HD4400 is recognized but only 4mb VRAM and very slow/glitches. Device ID 0x0a13 Revision ID 0x0009
  • Audio. Specsheet says I have Waves MaxxAudio Realtek ALC3234 controller
  • Brightness. Cannot adjust brightness
  • Power Button. Pressing it does nothing
  • Sleep. Selecting sleep from menu just dims screen but cursor still on screen
  • Card Reader. System Information says computer doesnt conatin any apple internal memory card readers. I cannot find any information on the model of sd card reader, any ideas where to find it?
  • Bluetooth.The DW1560 is a WIFI/Bluetooth combo, and now only WIFI is detected.
  • Misc. After entering my password it takes over a minute to enter the desktop, there is a spinning wheel.There is an eject button in the menu bar by the wifi and battery icon but this laptop does not have a DVD drive.

In order to obtain full graphics acceleration on your Intel HD4400, you need:

1) to use Rehabman's FakePCIID set of kexts

2) inject Desktop HD4600 id (0412) to the OS (i.e. pretend your mobile HD4400 is desktop HD4600)

3) inject the appropriate Azul framebuffer to the OS (presumably 0x0a260006)


You can do 2) and 3) either through Clover config or DSDT patch.

Boot to Clover GUI. Hit F4, this will extract the raw files to /EFI/Clover/ACPI/Origin.

I'm assuming you don't have any patched DSDT/SSDT at the moment. Compress the Origin folder and upload it here. I'll try to patch them for you.

Once you're in the Desktop, download DPCIManager.app. You should be able to get the device info under PCI List.

The config you have does have the audio patches, but you'll need the DSDT and the patched dummyHDA to work.

Will you be installing El Capitan?


Here are files for Yosemite. Replace your config.plist and Other folder with this. Make a backup first.

Place the 2 DSDT/SSDT in /EFI/Clover/ACPI/Patched

Install kexts in /EFI/Clover/Kexts/Other/SLE to /System/Library/Extensions with kextwizard or just copy them there.


Run this to repair permission and recreate cache


      sudo chmod -Rf 755 /S*/L*/E*
      sudo chown -Rf 0:0 /S*/L*/E*
      sudo touch -f /S*/L*/E*
      sudo kextcache -Boot -U /
