kayoone Posted July 16, 2009 Share Posted July 16, 2009 Hi there, i had Time Machine perfectly running for month. After install i got "Error obtaining mac address" but found some kext to fix that problem, it has worked flawless ever since. Then i replaced my Asus P5Q Pro motherboard with another P5Q Pro because the old one died. I restored my old OSX installation from an CCC image and everything was fine again, but now i get "Error obtaining mac address" again from Time Machine, but the fixed IONetworking.kext is still in place :/ So i googled a bit and found articles from mac pro owners who got their motherboard changed stating that TM stopped working because the new motherboard has a different mac address. I thought thats it! So i followed the steps and set up my new mac address and realized that it still didnt work, i also get that error when selecting a clean drive so it cant be the same problem. Now i reinstalled the patched IONetworking.kext over and over, cleared boot/ext cache etc to no avail, still gives me that damn error message... any1 has an idea on how to proceed instead of reinstalling the whole system ? Thanks! Link to comment https://www.insanelymac.com/forum/topic/175159-time-machine-stopped-working-after-motherboard-change/ Share on other sites More sharing options...
Daveta Posted July 16, 2009 Share Posted July 16, 2009 you have attached the hd at the same port? Link to comment https://www.insanelymac.com/forum/topic/175159-time-machine-stopped-working-after-motherboard-change/#findComment-1201838 Share on other sites More sharing options...
FKA Posted July 16, 2009 Share Posted July 16, 2009 I've had a similar problem taking a clone of my install to another machine. Final cut pro was crashing on startup and the error related to a network issue. After some fishing around i found that deleting /Library/Preferences/SystemConfiguration/NetworkInterfaces.plist then reboot, sorted the problem. data relating to thye NIC is held in the NetworkInterfaces.plist. Your new board has a new built in NIC I assume! ##EDIT# The info in the plist will have your old MB's NIC as EN0. deleteing the plist forces it to be re-cahed setting your new NIC as EN0 ..... I think !## D Link to comment https://www.insanelymac.com/forum/topic/175159-time-machine-stopped-working-after-motherboard-change/#findComment-1201907 Share on other sites More sharing options...
kayoone Posted July 16, 2009 Author Share Posted July 16, 2009 You, Sir, are my hero of the day! That did the trick, have wasted hours with that looking in the wrong direction. With the other mods i did to change the mac address of my backup it even resumes my old backups. Thank you!

I think !## D Yes, that was it! Before that I tried the "IONetworkFamily.kext replacement method" I found in the Inet, but no success.. Therefore thank you for that very important information! Running now iATKOS 10.5.7 on a GA-P35-DS3, hdisks over AHCI, Intel Q6700, 8GB Corsair 800MHz, using a 160GB Buffalo USB 2.5" drive for Time Machine and have a Sparkle GF 8800GT 512 MB CoolPipe (QE/CI ok.) furthermore a working D-Link DWL-G122 for WLAN But there is another issue, relating Finder: Preferences doesn't work! Clicking on it and the icons on desktop disappears for a second - and nothing happens (I would deactivate the delete-dialog - moving to trash) So most of us have our special difficulties configuring our Hackintosh- and especially I ask me: Why?... ...coz' I'm also an owner of an iMac 24" early 2008 since Feb. 2009 ;-) I think: It's the sportive moment which accelerate us to make our Hackintosh working perfectly... EDIT: Now, using the direct SL (10.6) method (untouched 7.5GB ISO file) all iATKOS-problems went away. The first boot into Snow Leo after installation from USB stick was out of the box! +QE/CI, +Wlan, +sound... No KP, no HALT - it's amazing! And using NullCPUPowerManagement.kext in /Extra/Extensions, the direct Update to 10.6.2 from the Apple menu was only one click ;-) without any error after update & restart.
