Hank Chill Posted December 17, 2008 Share Posted December 17, 2008 Hey all, I'm sure some of you have seen this error: "_CFGetHostUUIDString: Unable to determine UUID for host. Error: 35" I did a search on it and found that some have had some luck by adding a dict entry into the network interfaces plist, but I've had no luck. This error comes up every second or two for every application or process that runs, and it's really bugging me. Does anyone know why this is constantly coming up in the console, and perhaps a permanent fix? Thanks, --Henry Link to comment https://www.insanelymac.com/forum/topic/141562-_cfgethostuuidstring-error-35/ Share on other sites More sharing options...

Thanks, --Henry Hi Henry, For me the solution was (and i believe this is the reason why that error keeps flooding system.log) to edit /Library/Preferences/SystemConfiguration/NetworkInterfaces.plist, and search for IOBuiltIn, it should be false, change it to true, it might be more then one of course. Save the file and it should stop bugging you Link to comment https://www.insanelymac.com/forum/topic/141562-_cfgethostuuidstring-error-35/#findComment-1097307 Share on other sites More sharing options...

Thanks, --Henry You can try the attached file which has the patched IONetworkingFamily in it this should get rid of the errors you copy this file into the .kext of the same name probably best to clear the caches and reboot using the -f option if you need better step by step instructions for doing this then let me know.

Yes I need better instructions, I'm a noob when it comes to OSX. I've edited the NetworkInterfaces.plist, but everytime I reboot the value goes back to false. I would to try this method.

Alright you need to first download the file and extract it where it will most likely be in your Downloads directory. Now open the Terminal application it is located in the Applications -> Utilities directory once you have it open type in then hit enter key sudo -s you will now be asked to put in your password you set on install to become root user. First thing you want to do now is backup the original file using this command in the Terminal. mv /System/Library/Extensions/IONetworkingFamily.kext/Contents/MacOS/IONetworkingFamily /System/Library/Extensions/IONetworkingFamily.kext/Contents/MacOS/IONetworkingFamily.backup Second copy the new assuming the Downloads directory replace the UserName with your actual user name. cp /Users/UserName/Downloads/IONetworkingFamily /System/Library/Extensions/IONetworkingFamily.kext/Contents/MacOS/ Third check the permissions. ls -l /System/Library/Extensions/IONetworkingFamily.kext/Contents/MacOS/IONetworkingFamily -rw-r--r-- 1 root wheel 545904 29 Dec 19:27 /System/Library/Extensions/IONetworkingFamily.kext/Contents/MacOS/IONetworkingFamily If you do not see this part -rw-r--r-- then. chmod 0644 /System/Library/Extensions/IONetworkingFamily.kext/Contents/MacOS/IONetworkingFamily If not seeing root wheel then. chown 0:0 /System/Library/Extensions/IONetworkingFamily.kext/Contents/MacOS/IONetworkingFamily So now you have made sure of the permissions you need to delete the caches. rm -r /System/Library/Extensions/Caches rm -r /System/Library/Caches rm /System/Library/Extensions.mkext And reboot when you get to posting where the hard drive is first getting accessed hit the F8 key to get to the Darwin boot loader where you use the hit any key option to get to the command line where you type in then enter key -f this forces the reloading/caching of all .kext on the system so your changes will be seen.

Walgus Posted May 5, 2009 Share Posted May 5, 2009 Macuser's fix works good, though the error 35 is still present sometimes on like 10 lines at boot time. Here is a solution that i just found in another thread, which seems to fully fix it from what i can see, no more uuid errors on the logs. link 1 link 2 Link to comment https://www.insanelymac.com/forum/topic/141562-_cfgethostuuidstring-error-35/#findComment-1149022 Share on other sites More sharing options...

oldnapalm Posted September 1, 2009 Share Posted September 1, 2009 Chameleon 2.0-RC2 solves this problem for me, just add these lines to /Extra/com.apple.Boot.plist <key>EthernetBuiltIn</key> <string>y</string> Link to comment https://www.insanelymac.com/forum/topic/141562-_cfgethostuuidstring-error-35/#findComment-1246812 Share on other sites More sharing options...

Should I add it and just add those two key/string lines? Don't I need something around those two lines?
