MacOS Sequoia 15.3 won’t let me sign in. On my MacOS Sequoia desktop I open 3 applications:
- TextEdit
- A browser pointed at account.apple.com’s sign-in page.
- System Settings > Sign in with your Apple Account.

Clicking Continue in only the browser produces this:
I enter the verification code in the browser window and click Continue in the Sign in dialog box:
You can see that Apple Account in the web browser signed me in, but the Mac did not. In both cases the user id and password were typed once in TextEdit and then pasted into both windows. Why is this happening? The credentials presented to both platforms are identical.
