desmopro Posted April 2, 2011 Share Posted April 2, 2011 On the build 11A419 (Also call Developer Preview 2) the IONetworkFamily extension has been modified and support for Realtek card dropped. I have actually add realtek kexts from Snow leopard IONetworkFamily inside the new extension and its worked but Mac App store seem unsupported ("You don't have any GUID partition on the disc, ...") Test with DP1 kext is needed, but if you want to upgrade, remember to backup the first IONetworkFamily. Link to comment Share on other sites More sharing options...
MacFanatic76 Posted April 3, 2011 Share Posted April 3, 2011 Downloading the Realtek-driver for Mac 10.6 could also help, without having to replace IONetworkFamily.kext. Just extract the ".mpkg" after dowlnoading, copy over the AppleRTL8169* to /S/L/E Link to comment Share on other sites More sharing options...
FuManchu84 Posted April 12, 2011 Share Posted April 12, 2011 For me the installing the "RealtekR1000SL.kext" using kext utility works. For some reason the realtek installer doesn't. Link to comment Share on other sites More sharing options...
