Help me to install Mac Lion 10.7.x on Dell Latitude E5420

[chan chua]

Hello,

 

I bought a Dell Latitude E5420 with this configuration :

Intel core i5 -2410(2.3GHz)

8GB DDR3 RAM, 320G HDD SATA

Intel® HD Graphics HD 3000 14" HD WLED True-Life (1366x768)

Broadcom Gigabit Ethernet and Dell Wireless 1501

 

Firstly, I tried many times to install as instructed :

- Boot from [url="http://www.insanelymac.com/forum/topic/279450-why-insanelymac-does-not-support-tonymacx86/"]#####[/url]

- Install the SL 10.6 retail DVD

But I always get this error message during the setup :

"The installer could not copy the necessary support files". I also restored the DVD to the hard disk partition but it does not change.

 

Later, I get iATKOS L1 DVD and install perfectly on my Dell.

 

After reboot, I had to type boot options : -f -s -v to get into the Lion system. With this, I have sound, webcam and keyboard functions. The wired/wireless, video card and power management do not work.

 

If I run [url="http://www.insanelymac.com/forum/topic/279450-why-insanelymac-does-not-support-tonymacx86/"]#####[/url] 4.0.3 with some options like :

o [url="http://www.insanelymac.com/forum/topic/279450-why-insanelymac-does-not-support-tonymacx86/"]#####[/url] Install

o System Utilities

o Drivers & Bootloaders

 Bootloaders

• Chimera v1.5.4

 Sound

• Voodoo HDA 2.7.2

o Mac BookPro 8,1

o Osx86 Software

o Extension Migration Tool

 

then I will get the video with its resolutions (1366x768) but I lost sound. It stop at that even i tried many other options in [url="http://www.insanelymac.com/forum/topic/279450-why-insanelymac-does-not-support-tonymacx86/"]#####[/url] or get other kexts from internet.

 

Could you please help me how to make this nice laptop installed with latest Mac OS X Lion.

 

Thanks for all your help !!!
