Hi all,
this my first post in your forum, but thanks to your nice tutorial, I was able to install succesfully OSX on a D420 as well as a D430; The only remaining lacking thing is the SD card reader. Yersterday; I downloaded the Dell Post Installer v1.4.1 and just installed the SD Card reader and ... It worked ! The SD card was detected, the content was accessible. However, Sleep was disabled and the system hanged up as soon as I removed the card. I saw that the Kext version was v3, so I tried with newer versions of iOSDHCIBlockDevice.kext but none of them were giving positive result.
I hope it helps.
Regards,
John Jaune
