Anyone have any luck solving this one?
I submitted a support ticket with Apple, but they've been so far unable to figure it out.
+1, after update 10.6.8 came the error "No GUID is available. Contact Support for assistance." program in Mac App Store.
+1, all i want to do is spend some money...
i have the same problem since update to 10.6.8 ... 😟
Aside from the NetworkInterfaces.plist, I also see com.apple.airport.preferences.plist and com.apple.network.identification.plist that I'd like to trash as well to see if that causes any different behavior.
I'll try that when I get a chance and report back.
In the meantime, anyone else have any ideas?
i deleted all files in /Library/Preferences/SystemConfiguration and restarted the system
but it didn't solve the problem
(btw: in my com.apple.boot.plist the parameter EthernetBuiltIn is set to Yes)
I too have the same issue after update to 10.6.8, all the suggestion here didn't work for me.
Obviously i now cant update to Lion when it's released.
I've done everything bar reinstalling system, surely i shouldn't have to do that??
PLEASE, any ideas, every other forum has the same advice about deleting network interfaces and plist files but this just does not work.
Yeah, I know, it's pretty frustrating. I haven't been able to sit down and spend much more time with this, but I doubt if I'm going to be able to find a solution.
+1, same "No GUID is available. Contact Support for assistance." error after updating to 10.6.8
Yup, same problem since going to 10.6.8. :-/
I have also had the same problem after upgrading to 10.6.8. But just tried to login to Appstore a minute ago and it worked fine again. I haven't done anything ex. deleting NetworkInterfaces.plist, or modifying com.apple.Boot.plist. Maybe they have fixed the problem?!
Anyway.. maybe this solution could work for some of you:
I found an Apple article on deleting that network preferences. It has the steps explained a little better for anyone who is nervous about deleting stuff:
I have the problem with the following machine:
Model Name: MacBook Pro
Model Identifier: MacBookPro4,1
Processor Name: Intel Core 2 Duo
Processor Speed: 2.5 GHz
Number Of Processors: 1
Total Number Of Cores: 2
L2 Cache: 6 MB
Memory: 4 GB
Bus Speed: 800 MHz
Boot ROM Version: MBP41.00C1.B03
SMC Version (system): 1.28f3
I have reformatted and gone back to the clean OSX 10.6.8 install and still nothing.
Yikes, well, I guess no point in trying that. I might, however, do a reformat and go back to 10.6.7, since it was definitely working with that build.
confirm that deleting the plist no longer works in 10.6.8. bummer.
pretty sad and expected by apple. Some bugs they have have been around for years and they still havent' fixed them. Once they get their PR for new features, i t doesn't matter to them that they have bugs
