macos – Why cannot I signal into iMessage on OS X 10.9?

Answer

1. In case you just lately tried to signal into iMessage, wait at the very least half-hour with out trying to sign up.

2. Open System Preferences → iCloud. If already signed in, signal out.

3. In System Preferences, enter your Apple ID and password, and click on “Signal In”.

4. Wait till you obtain an Apple ID Verification Code on one among your different units. Don’t use this code in System Preferences!

5. Within the Messages app, signal into iMessage with (1) your Apple ID and (2) your password adopted by the verification code you obtained. For instance, in case your password was “correcthorsebatterystaple” and your verification code was “123456”, you’d enter “correcthorsebatterystaple123456” within the password discipline in Messages.

Messages ought to sign up efficiently! If you don’t use iCloud for anything in your Mac, you’ll be able to cease right here. In any other case:

6. Return to System Preferences. Try to signal into iCloud together with your Apple ID and password (no verification code).

7. Wait till you obtain a brand new Apple ID verification code on one among your different units.

8. In System Preferences, sign up together with your Apple ID and your password adopted by the newest verification code.

Clarification

I do not know what modified on Apple’s servers, however for some cause, Macs operating OS X 10.9 are restricted to 1 iMessage sign-in try per roughly half-hour.

This conflicts with Apple’s normal circulate for older units. Usually, the method appears like this:

1. Enter your Apple ID and password.
2. Obtain a verification code.
3. Re-enter your Apple ID and your password adopted by the verification code.

It is a actually intelligent system! It permits older Apple software program (from earlier than the introduction of two-step verification) to proceed signing in to fashionable accounts, with none client-side updates. Nonetheless, it requires customers to try to sign up twice in a row, and Messages can solely try to sign up as soon as each half-hour. That is longer than the time it takes verification codes to run out.

Fortunately, System Preferences will not be restricted to 1 sign-in try per half-hour, and Apple does not appear to thoughts that we’re utilizing the code in a unique app from the place we requested it.
