An error has occurred forbidden(10403)



Hi there, somas_sk!


Thanks for reaching out to the Apple Support Communities! It sounds like you are having issues with installing the 10.12.1 update to your computer. I know how important it is to be sure the computer updates properly. What you might want to try next are some specific restarts. Check out this article to Try safe mode if your Mac doesn’t finish starting up. While this article speaks about the computer not starting up properly, it can also run repairs and stop startup items that can cause issues with installing updates.

Another option you can try is in this article: How to test an issue in another user account on your Mac. This will allow you to check to see if the issue is user specific or system wide.

Just be sure you try to install after each step.

Cheers!

I had this same error. I looked around for a response that would solve it for me but didn't find one. After thinking on it some I decided to check what all was trying to be updated at the same time as the new OSX version. I realized it was trying to update iTunes as well. So I selected the OSX update to install first by itself and that worked. Went back into software update afterwards and was able to then install the rest of the updates including the iTunes (which I assume was giving the 10403 error) with no issues. Hope this helps.
