Sotirios Papakonstantinou Posted March 29, 2015 Share Posted March 29, 2015 Hello! I'm not sure if this has been asked before, but I couldn't put the correct key words to find it. Please give me the thread's link. I have taken an old HP Pavilion notebook, and a spare disk and decided to install Mac OS X 10.6 to see how compatibility goes and experiment. A common problem is that when I upgrade from 10.6.3 to 10.6.8 with the combo upgrade, my LAN and WLAN cards stop working. No matter what drivers (kexts) I tried, I couldn't make them work properly again and the only solution is to format and reinstall Mac IS X 10.6.3 from iAtkos DVD. The question: is there any way to backup the working drivers and make the combo upgrade? Then I could restore them and the LAN works as it should. Alternatively, can I select which components are being upgraded, so I make sure kexts aren't? Thank you in advance. PS: My specs: HP Pavilion zv6000 series, AMD Athlon 64 3200+ 2GHz (I use legacy_kernel to boot), ATI Radeon Xpress 200M chipset, ATI Mobility Radeon Xpress 200 128MB VGA (basic display, but I don't care), Audio ATI SB400 AC'97 (no audio yet), Reatlek RTL8139/810x LAN, Broadcom BCM4318 WLAN, TI PCIxx21 Flashmedia (not working), TI TSB43AB22 IEEE 1394.

Allan Posted March 29, 2015 Share Posted March 29, 2015 Every time there is an update, we have new versions of kexts. You can try to save the kexts in a Pendrive and then, reinstall. What's your WLAN and LAN driver?

fantomas Posted March 29, 2015 Share Posted March 29, 2015 hi for your LAN (RTL8139), you need to add AppleRTL8139Ethernet.kext in System/Library/Extensions/IONetworkingFamily.kext/Contents/Plugins for your WLAN (BCM4318), you need to add AppleAirPortBrcm4311.kext in System/Library/Extensions/IO80211Family.kext/Contents/Plugins repair the permissions and rebuild the kache reboot enjoy! 1 Link to comment https://www.insanelymac.com/forum/topic/305369-apple-upgrade-without-affecting-drivers/#findComment-2124074 Share on other sites More sharing options...
