Checking software updates in the Mac app store on iMac using Mountain Lion and just now getting my first error. Can someone tell me why? and how to fix? Could it be the server is down since they just annouced today the new iPhone, iPods?
iMac, OS X Mountain Lion (10.8.1)
Try adding the DNS Servers: 8.8.8.8 & 8.8.4.4
Open System Preferences > Network > (Select your means of connecting to the network) > Advanced > DNS
Click the +
8.8.8.8
8.8.4.4
My system was already configured with the Google DNS servers in my network settings, and I'm still getting this error.
I'm also getting this error (just today) and following your instructions didn't help. Thanks Yuengdog!
Anyone else have any ideas?
I'm experiencing the same error:
The operation couldn’t be completed. (NSURLErrorDomain error -1100.)
I've tried renaming and also deleting /private/var/folders as recommended elsewhere, but no luck.
Having same issue (NSURLErrorDomain error -1100.) Macbook Pro at work can do the updates. I just connected to work and connected to Macbook Pro there and it works fine. Macbook Pro at home will not work. Routed Macbook Pro at home through work internet connection - no dice will not update. Error message same through either internet provider.
Both running Mountain Lion 10.8.1
Facing the same issue - running Mountain Lion 10.8.1.. Is there any help
I stumbled upon some Dutch users facing this error and figured I'd check my situation. Strangely enough, I also receive this error now, even though I've never seen it on my system before.
I figured it would be an error on Apple's side (i.e. Server-side), so I think I'll just wait. However, I did find that NSURLErrorDomain error code=-1100 means 'The Requested File does not exist'. I would, in that case, like to know just WHAT file doesn't exist, at I'd be unable to repair it without this info. On the other hand, I have not knowingly deleted any files on my system, let alone any critical files (i.e. essential to the system).
NSUrl can be used to open a number of different connections to a number of different things. It is not a DNS Error as two computers configured the same do not respond the same. Whatever the case, the problem seems to be growing, not resolving. It will be curious to find out just what it actually proves to be.

LOTS of people are receiving this error (including myself). It probably has nothing to do with your computer at all but the fact that Apple's servers probably weren't prepared for the massive numbers of attemped updates, specifically for the iTunes update. DNS fixes have been posted, but these don't work for me. Unfortunately, probably the best solution is either to wait or, if you're looking for the update to iTunes, go to: http://support.apple.com/downloads/ where you can find the latest software. After downloading the latest version of iTunes, mine was listed as being the latest version.
@Doc Maynard; @Shylocxs: The web page you listed here is the one where I foudn error code -1100 to mean that 'The Requested File Does Not Exist'. So I'd already figured it wasn't quite a DNS error in the first place.
I think what happens is this (purely structural; underlying procedings may be completely different):
If things are actually happening along these lines, then that would explain the specific error code. Anyhow, I do indeed think that it's better for us all just to wait for a fix.
I tried all 'fixes' mentioned here, thogh none by carrying out destructive measures. Unfortunately, none of them worked for me, so I have reversed everything to the way it was beforehand.
For those of you who want to know: OS X Lion (10.7) is also affected, albeit in a different way. Users in the Netherlands are reporting seeing the very same code mentioned here when launching Software Update through [Apple] > Software Update ... in the menu.
Although Software update doesn't run through the App Store in any way in versions before Mountain Lion, it seems that talkback happens through the same connection (i.e. to the same server) for software updates. So this would strengthen my thought that this error be caused by a server-side issue with Apple. Also, it clarifies why I AM able to download new Apps, yet am UNABLE to update existing (system) software.
Interesting side note... Took my personal Macbook Pro to the office (Cox: Office vs Comcast: Home) and it connected and updated fine. This is the same Macbook Pro that 15 minures ago wouldn't update at my home. My other Mac at house still having the issue. Interesting since I routed this Macbook Pro out through work earler and it wouldn't update.
Side Note:
Error 1100 is not listed in the link I posted earlier, and their is no refernce to it being a file error there. NSUrl is a Cocoa API for connecting to any number of data streams as I stated earler.
I think it's not ISP-related, but rather geographical in some way. I have two different connections through which I can access the internet, both running through different ISPs. Both give the very same issue using Software Update (App Store > Updates).
Here appears the same error: NSURLErrorDomain error -1100 in Mountain Lion
Any solution??
thank you
Hi guys, i had the same problem till few minutes ago when i try to flush DNS cache to resolve the problem and it works for me!!! How to do this? It's simple:
Open terminal and copy and paste this command
sudo killall -HUP mDNSResponder
It will ask your password, insert it and press enter, that's all!
Just tried this but still got the same error message. Nice suggestion, though.
