mRusso87 Posted May 30, 2008 Share Posted May 30, 2008 Hi All, I am running OS X 10.50.2 and I am getting a problem when backing up data with time machine. See log below. The hard drive is an internal SATA drive(250gb). It has been freshly formatted HFS+ (journaled). I have tried various tests as to what it backs up and it fails regardless (excluding system files etc.) Is there any know resolution? Thanks in advance.

coolied Posted May 30, 2008 Share Posted May 30, 2008 it has to do with IONetworkingFamily.kext; I can't remember exactly where I downloaded the one I had to use, but I had the same problem and it's now fixed. Do a google search for "IONetworkingFamily.kext time machine" and you'll be lead to some good info (mostly in this forum) Has something to do with Time Machine reading the network card's MAC address, of all things, that's how Time Machine figures out it's using the correct backup volume, from what I understand........ Not sure though, basically a total newb here speaking...... *LOL* EDIT: this post should get you up and running! http://forum.insanelymac.com/index.php?showtopic=68708 (I'm not responsible if it doesn't work/hoses your system/etc) Link to comment https://www.insanelymac.com/forum/topic/107717-time-machine-error-18/#findComment-764705 Share on other sites More sharing options...
mRusso87 Posted May 30, 2008 Author Share Posted May 30, 2008 Mate you are a champ. That method below worked for me. http://www.megaupload.com/?d=HWVMONUU After placing it it /System/Library/Extensions sudo -s *password* rm -rf /System/Library/Extensions.mkext chmod -R 755 /System/Library/Extensions/IONetworkingFamily.kext chown -R root:wheel /System/Library/Extensions/IONetworkingFamily.kext reboot, and keep your fingers crossed From: http://forum.insanelymac.com/index.php?showtopic=68708 Link to comment https://www.insanelymac.com/forum/topic/107717-time-machine-error-18/#findComment-764786 Share on other sites More sharing options...
coolied Posted May 31, 2008 Share Posted May 31, 2008 Glad it worked out for you! Drove me nuts for a few hours looking for a fix, mostly because the networking KEXT was the last place i'd think to look for a problem with a LOCAL backup solution......... I figured it was a SATA problem or a GUID problem..........

mRusso87 Posted June 1, 2008 Author Share Posted June 1, 2008 Definitely the last thing I would have thought of, glad it all works now tho Link to comment https://www.insanelymac.com/forum/topic/107717-time-machine-error-18/#findComment-766222 Share on other sites More sharing options...
dparada78 Posted August 8, 2008 Share Posted August 8, 2008 might be an old thread but i had the same problem...downloaded the ionetworkingfamily.kext and installed it but it didnt work... until i realized that i needed to have my usb wireless plugged in at the same time as my external usb drive. i dont know why. i dont use my ethernet port because it drops out all the time...had to use wireless.... and for some reason it must be plugged in for time machine to work!
