(NSURLErrorDomain error -1012.)

Hi everyone,


Since 4 days my system isn't running as it used to be. It all started with Safari not loading several websites. It seemed this error only had to do with https:// websites. I tried to fix that problem with resetting my login-keychain. But when I tried to do that the program said the process can't be done, because I have not the needed rights to do that. (I was logged in as admin!!!). So I canceled the process and surprisingly my login-keychain was gone. GONE. AWAY. I freaked out because that was not what I wanted - and the system told me that I have not the rights to do that! HUH? How could this happen?


But now I regonized that my Mac App Store won't load any updates. I don't know since when this error occurred but I think it has to do with the deletion of the login-keychain. The error said: (NSURLErrorDomain error -1012.)


Can anyone help me to fix this problem?

For issues related to downloading updates and error -1012


  • Disable anti virus softwrare if installed
  • Check your firewall settings in System Preferences > Security & Privacy > Firewall > Firewall Options
  • Check firewall settings on your router and internet modem
  • Make sure Gatekeeper is enabled


Open System Preferences > Security & Privacy then select the General tab.


Make sure either Mac App Store or Mac App Store and identified developers is selected. If that area is grayed out, click the padlock icon to proceed.

Please read this whole message before doing anything.

This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.

The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of the file system or of certain system caches.

Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode and log in to the account with the problem. You must hold down the shift key twice: once when you turn on the computer, and again when you log in.

Note: If FileVault is enabled, or if a firmware password is set, or if the startup volume is a Fusion Drive or a software RAID, you can’t do this. Ask for further instructions.

Safe mode is much slower to start up and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal startup may also be somewhat slow.

The login screen appears even if you usually login automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.

Test while in safe mode. Same problem?

After testing, restart as usual (not in safe mode) and verify that you still have the problem. Post the results of the test.
