NSURLErrorDomain error -1100

Error 1100 is happening only on Macs with illegally installed Mac OS 10.8.x

Just pay $19.95 and be happy with updates 🙂

Do not talk nonsense! OS X 10.8 I got a new MacBook, but still have the same problem is present. Once more I must pay $20?

I had the same error 1100 on one unlegalized Mac today morning, then bought licence and no error 1100 happens anymore during update.

Some new Macs are coming with 10.7 only and 10.8 shall be legalized during special procedure, not just upgrade thru downloaded 10.8 image.

This is NOT correct. I have a fully legal install of Mountain Lion (10.8.x) and I am getting this error message.

OS X 10.8 I have fully licensed, but the error message I get!

Same here.. error but i have everything licensed. Here u can see OS X Mountain Lion

And here error.

That's not right. At all, Karpatchev. Don't know how one would assume that. I've always been legal and I was getting same message.

DNS fix worked for me.

I'm not surprised that someone with such a lack of judgement as to have an illegal copy of the system would also make such a nonsensical conclusion.

There is no way in which Apple actively checks legalty of OS X, other than DSMOSX.kext. So this error doesn't 'only occur on machines running illegal copies of OS X' as some of us seem to think.

Moreover, my copy of OS X is legal, and still generates this error.

Using Google, I have found resources which suggest that 'NSURLErrorDomain error code =-1100' means that 'the requested file does not exist', but seeing as I have only ever seen this error as of today (i.e. never before today), it would seem that this error lies on Apple's side. Add to that the facts that:

a) there are MANY more persons who experience this error, in all kinds of locations, and;

b) all reports considering this error were started today

and one can be almost 100% sure that the issue IS on Apple's side. I'm not saying it definitely is, as there are some people for whom a 'DNS fix' works (i.e. changing the DNS servers to Google's DNS servers in your internet connectivity device). But there seem to be just as many (me included) for whom this fix does not work. Add to that the afforementioned facts and you'd just have to be sure. And, to conclude, someone mentioned in this topic that his logs show a 503 error (Service Unavailable). This would seem that my explanation of the error mentioned (File not available) could only hold true if this file were to be searched for on a remote location... I guess there's little more to it than just wait...

Moreover, my copy of OS X is legal, and still generates this error.

Yup, my point was that the guy saying that only illegal copies of Mac OS X are causing this problem. That's nonsense.

Some things I have heard indicate that this may be a regional problem, though what parts of the world are affected I don't know yet. A few people have been helped by deleting the following preference file (paste the path into the Go -> Go to Folder window in the Finder to locate it), though most have not:

~/Library/Preferences/com.apple.SoftwareUpdate.plist

Waiting for the servers to be fixed would appear to be the only fix available for most people.

lo mismo me esta pasando desde hace 2 dias... por un lado me quedo mas tranquilo que no soy solamente yo..

que hay que hacer???

I'm experiencing the same problem!

I've NO illegal copy of Mountain Lion.

It started after I made the last software update some days ago. Since then I wasn't able to update my Mac again.

Please help!

Try the DNS serverfix listed in this message. It worked for me.

Good luck! Tom

didnt work here

Just a thought, since I am having this issue too.

My Mac Mini server (which is running Lion server) downloaded and installed iTunes 10.7 just fine. When I went back to my iMac and tried to update my software, I got the above error. My iMac was using my Mac Mini as a software update server. I switch it to use Apple's servers and the error message went away. However, the App Store can't find the new iTunes and updaate my iMac. It says "No updates available".

If I try to point the software update server to be my Mini again, I can't do it.

Sorry, but I do not have more time to investigate right now, that's all I can offer.
