iCloud login problem on Sierra, High Sierra? Try this.

Hey Guys, Apple just released their own new Apple IST CA 2 - G1 certificate in the PKI- Site, it also expires 20250507 but is different from the other ones it installs in the system column, just installed it and everything keeps working... Just going to leave everything as is (like in dgd's post) since it's working...

So I did this....

I went into all certificates listed in a couple of my earlier posts that I'd set trust to "always" . I set them back to "System".

Rebooted (don't know if necessary but why not).

So far all working fine.

I had these options come up after double clicking it, in Keychain access:

• Login
• Privateencrypteddatak
• Microsoft intermediate certificates
• iCloud
• System

Assume its to go in the iCloud keychain?

This thread might provided a little info on the -25294 error: https://developer.apple.com/forums/thread/675290

That certificate has not been updated at Apple PKI - Apple

I downloaded the file and hit space bar in Finder to view it and expiration date has not changed.

But when I tried choosing iCloud, this was my error message:

I'm just happy that my iCloud is back up and running and wanted to share the solution with others.

THANK YOU!!!! You have done what 24 hours of contacting Apple Support didn't do... This is the solution!! They wanted me to reinstall MacOS and that would have been a pain is the ***...

OK, reboot done twice as all kind of problems. Looks like OK now, I hope I am not dreaming. Thanks so much for the guidance and patience. I hope no need to come back here!

Thanks! That fixed! However, I noticed that the intermediate cert expires on May 20, 2022...I assume we'll need to update again?

Regards, Patrick

I have the same question about the expiry date... Coming soon...
