Dell Latitude D420's


Recommended Posts

I got to install Snow Leopard 10.6.3 on a friend of mine's D420 and talk about fast.


Everything was working great, that is UNTIL I updated to 10.6.8 in whereby I lost WiFI, Bluetooth and USB


Anybody else with update issues with Snow Leopard?


EIDT: I found this in another post, I havent tried it but I think it'll work:



Hi all with WiFi problems after update to10.6.8.


I found the solution for my D620 finally! Here are the steps:


1) You must add this key in smbios.plist ... SMboardproduct Mac-F4208CC8

2) Delete the file NetworkInterfaces.plist from /Lybrary/Preferences/SystemConfiguration/

3) Delete Network Interfaces from System Preferences/Network

4) Roll back the files Apple80211Monitor.bundle to 10.6.7 version

5) Roll back the IO80211Family.kext and IONetworkingFamily.kext to 10.6.7 versions

6) Repair permisions ...


Add network device to System Preferences/Network and thats all ... everything works !!
