Install OSX Mountain Lion 10.8.2 on Dell Inspiron 3520 with SSD. Windows 8/OSX UEFI dual boot. 99% Working, NO DSDT REQURED!!!

About this article

This article is a complete guide of installing OSX Mountain Lion 10.8.2 on Dell Inspiron 3520 (Purchased in Jan 2013) for experimental purpose only, before read this tutorial, you would need some basic knowledge as below:

  1. Bios settings
  2. OSX shell
  3. Encourage & Patient
    4. If you received kernel panic, don’t worry, just reboot couple of times.

I do not take any responsibility for any damage may occurred to your device, & you may be out of warranty if you replace the hardware  by yourself. So please use it at your own risk. 

Hardware Specification:

Intel i5 3210M  2.5GHz 3M

6GB DDR 3 1600MHZ

1TB SATA Hard Drive

8 x DVD Writer

Intel HD 4000 Graphic

Dell 1703 mini adapter

I bought some component for upgrade

Purchased components for upgrade (Optional):

1 x 4GB DDR 3 1600 memory

1x SATA Caddy bay to replace DVD rom +

1 x Sandisk SATA III SSD

1x Atheros 9285 wifi mini card.

This model of Dell 3520 is very effortless to replace components, you do not need to remove any screws on the back, all you need to do is use a flat screw driver to open the 4 holes on the top of the keyboard pad. Note: moreover you don’t have to remove the keyboard pad completely, all you need to do is replace the memory & wifi card & replace the cadday bay by remove 3 screws under the keyboard pad. I did not made a video for this section as I found this video on Youtube. NOTE: you do NOT have to add any memory, harddrive, or wifi mini card, you can use an OSX compatible USB wireless card if you wish.

1. Prepare Installation Media

Buy OSX mountain lion from Mac store. Install the Unibeast to your USB driver which has storage more than 8 GB.
You probably need a working Mac OS / OSX system to complete this step.

2. Installation

Reboot after installation is complete, press F2 on Boot & switch off the “Safe boot” option, save & exit then press F12 on boot  and in legacy boot section & select boot from USB drive.

After boot from the USB with Legacy USB Disk, use disk utility to format SSD drive, install OSX on the SSD disk. The installation should be no error as Dell 3520 has a very satisfactory compatibility for OSX.

3. Install Multibeast

Use this configuration


The reason  to install Chameleon is  Chameleon is much more easier to configure & if you did anything wrong in Clover configuration, you can easily boot up from Chameleon with legacy option.

Please do NOT install any audio/video driver from Multibeast, they are a bit outdated, download the driver  as below.

4. Install Audio/Network Drivers

There are only a few kext needs to be installed, you can install them use Kext Utility. You can download them from here:

Audio Driver: Download

Wifi Driver: OSX has native support with Atheros 9285 mini wifi card. However you do need to rollback to this IO80211Family.Kext

Battery & PS2 Controller: Download

Restart your laptop after install these Kext

If you have experience with Chameleon, you can inject the device code for video in /Extras/org.chameleon.Boot.plist, & use PCIROOT=1 to enable Lan. This will make your Graphic card, App Store work, yet Team Viewer & iMessage will not work we use Clover.

This is my version of org.chameleon.Boot.plist

EthernetBuiltIn Yes GenerateCStates Yes GeneratePStates Yes GraphicsEnabler Yes Graphics Mode 1366x768x32 Kernel mach_kernel Kernel Flags darkwake=0 PCIRootUID=1 Legacy Logo Yes Timeout 2 UseKernelCache Yes device-properties 7f0000000100000001000000730000000200000002010c00d041030a000000000101060000027fff04002c0000004100410050004c002c00690067002d0070006c006100740066006f0072006d002d006900640000000800000003006601140000006800640061002d0067006600780000000d0000006f6e626f6172642d31

NOTE: DO NOT USE GraphicsEnabler=Yes before you put the inject the device code, otherwise you will obtain a black screen after reboot

So far, you should have a working OSX installed, graphic card, network access, audios works etc.

Next we will need to install Clover & enable dual boot

5. Install Clover

Download Clover from and install as “Unpack” to your OSX disk.
Next you need to mount the EFI drive to a folder.

Open Application->Utilities->Terminal & input

mkdir ~/efi sudo mount_msdos /dev/disk0s1 /Users/saga/efi cp -R /EFI ~/efi/

modify ~/efi/EFI/config.plist with text editor
This is my config.plist file

ACPI DsdtName dsdt.aml Graphics CustomEDID 00FFFFFFFFFFFF0030E4DC020000000000140104902213780A09159D5F599B2719505400000001010101010101010101010101010101B01D56C650002A302430350058C210000019EC1356C650002E302430350058C210000019000000FE00394858584A803135365748340A0000000000004131960100000001010A202000F7 GraphicsInjector Yes InjectEDID Yes VRAM 512 PCI DeviceProperties 7f0000000100000001000000730000000200000002010c00d041030a000000000101060000027fff04002c0000004100410050004c002c00690067002d0070006c006100740066006f0072006d002d006900640000000800000003006601140000006800640061002d0067006600780000000d0000006f6e626f6172642d31 HDAInjection No LpcTune No PCIRootUID 1 StringInjector Yes USBInjection No SMBIOS BiosVendor Apple Inc.

you need to alter DefaultBootVolume to the volume of your OSX. Also you need to obtain the legal information for the OSX such as bios version or serial number, you can use other software to generate it.


Download these files & copy them to ~/efi/EFI/drivers64/ , This contains HFS & NTFS driver for clover, they are not included in Clover installer by default.

Open ~/efi/EFI/BOOT/refit.conf

this is my configure file

# # refit.conf

6. Change Bios Setting to add UEFI option & boot from Clover

In Dell 3520 bios , you are able to add additional UEFI boot file without using EFI Shell, which you can add Clover to your bios boot list easily. Simply select add UEFI boot file in bios setting & select the SSD disk -> /EFI/BOOT/CLOVERX64.efi, donate it a name “Clover UEFI” or whatever, alter the boot sequence in UEFI boot section, make it on the top of the list, save & exit. You will find on your next boot you will find the Clover boot loader screen & your OSX driver is selected as default boot device.

Finally you received a 99% working OSX working on DELL inspiron 3520, the only thing not working is the sleep, however you may resolve it with DSDT yet this will not be introduced in this tutorial.
