Well we have a "Dell Latitude D620 Thread" that is pinned. Please post your questions there.

Follow the guide again, but instead of using EDP to prepare the Extra folder, download the one that matches your D620 model (GMA950 Graphics or nVidia graphics) from the link provided. EDP does not work when making Extra folders for install usb drives. Also, turn on your D620 and on the dell screen, hit F2 and go to System Info. If it says "Core Duo", don't even attempt it. If it says "Core 2 Duo", there is still hope.

Ethernet doesn't work out of the box for OS X. You need to install EDP. Once EDP is installed and you have restarted, go to Network, and it should say a new Network Interface has been added to your system, called Ethernet. Now you are able to use Ethernet.

Hi, Follow this guide: https://osxlatitude.com/index.php?/topic/756-mac-os-x-lion-install-guide-for-d620/ It should work on your D620 model very well.

Your Intel PRO Wireless Card will not work with Snow Leopard, since Apple never used that card in their machines and there is no kext for it. There are Broadcom cards made for your model that will work in Mac OS X (Dell Wireless 1490 Dual Band). Good luck!

Get the EDP package for Snow Leopard, put that on a CD or Flash Drive and install it on the D620, restart, and everything should be back!

Hi, Follow this guide: https://osxlatitude.com/index.php?/topic/756-mac-os-x-lion-install-guide-for-d620/page__pid__5351__st__20#entry5351 It may be easier from there

At this point in time, I would say stick with Snow Leopard. The compatibility is much better as of now, and it runs way more smoother than Lion, even if Snow Leopard doesn't have iCloud. It is also way more smooth on the Hackintosh community, but that will improve as times go on.

I updated to 10.7.2 and rebuilt my kext configuration with EDP 2.1, and I booted using arch=i386 -v and was able to get into OS X. I had noticed it removed the arch=i386 boot flag, so I re-added it and now I can get in 10.7.2 with no problem. Still have the shutdown/restart problem. Don't know if that will be solved later on or not.
