Hello,
I am experiencing a persistent login loop when attempting to access the Apple Developer portal and App Store Connect on my Mac. Every time I submit my credentials on developer.apple.com or appstoreconnect.apple.com, the browser returns the error message: "Failed to verify your identity. Try again."
Here are the specific details of my setup and the issue:
- System Specs: MacBook Pro with M1 Pro chip, running macOS Golden Gate.
- Cross-Device Status: The exact same Apple Account credentials work perfectly on my iPhone, allowing me to log into the Developer app and manage apps without issues.
- The Loop Behavior: The error triggers immediately in the web browser on my Mac during the web authentication handshake phase. It does not even reach the stage of sending a 2-factor authentication prompt to my trusted devices.
- Troubleshooting Already Attempted:
- Tested multiple web browsers (Safari, Chrome) in standard and Private/Incognito windows.
- Wiped all browser caches, cookies, and completely disabled all extensions and adblockers.
- Created a brand-new Administrator user profile on macOS, but the web portals throw the exact same identity verification error there as well.
- Switched network routes entirely by testing on regular Wi-Fi and routing through an iPhone Personal Hotspot (cellular data) to bypass local router/DNS blocks.
- Manually searched for local cache directories (com.apple.iCloud / com.apple.AppleID), but these paths do not exist.
Has anyone found a way to break out of this identity verification loop?
Thank you!
