ptesone Posted September 23, 2011 Share Posted September 23, 2011 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 !! Link to comment Share on other sites More sharing options...
