Error -9813

Every time I try to check for available downloads, I'm told 'could not complete your request, error -9813.' I've found the meaning of many other error codes, but not this one. Anyone know?

macbook pro, Mac OS X (10.5.8)

Just did a chat with support - didn't help me, but might help others:


The "Error 9813" alert occurs when there is an issue with the root certificate in a Keychain. Root certificates are stored in a system keychain located at : /System/Library/Keychains/X509Anchors These roots are used by Mac OS X system software to evaluate trust for secure web connections, secure e-mail, and other PKI interactions.


There are a few possible resolutions for this issue: 1.Quit iTunes, open Safari, and choose Empty Cache from the Safari Menu. Return to the iTunes Store and test to see if the issue is resolved 2.Use Time Machine or another backup to return to a previous working root certificate (X509Anchors) 3.Copy the root certificate over from another Mac. This solution is proposed in a mail troubleshooting Mail 2.0 Help Unable to verify message signature. Copy the "X509Anchors SystemRootCertificates.keychain", and "SystemCACertificates.keychain" files from another computer running the exact same version of Mac OS X as your computer, restart, and test. 4.Reinstall Mac OS X on your computer.

Note: If you choose to copy over contents of /System/Library/Keychains, be certain that the computer you are copying the file over from is running the same version of Mac OS X. You can compare Mac OS X version numbers by going to the Apple () menu and choosing About This Mac.

I spoke with support and went through every step outlined in the above post, except trying to bring the x509anchors from another computer. Nothing has helped. This includes completely reinstalling Mac OS, and that still did not fix it. Not sure what else I could possibly do? I think this is something on Apple's end, not just system settings.

I have been having this problem for almost 24 hours. Funny thing is, I get one error message on my 'puter (-9813) and one on my iPhone(Cannot connect to the Store. A secure connection could not be established. Please check your Date and Time settings.) I did check the date and time, all fine. I turned off auto, turned it back on, rebooted. Then I checked with my laptop and got the 9813 error. I did the keychain repair thing and rebooted more times than I want to admit. I've not fixed anything. I was comforted by the fact that I discovered this must be out of my hands, so I'm just chirping up so everyone knows there are lots of us in the same boat. Hey, Apple! Hellllllp!
