macos – How do I signal into iMessage on OS X 10.9 Mavericks?

Resolution

1. If you happen to lately tried to signal into iMessage, wait not less than half-hour with out making an attempt to check in.

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 in all your different gadgets. 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 acquired. 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 check in efficiently! If you don’t use iCloud for anything in your Mac, you may cease right here. In any other case:

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

7. Wait till you obtain a brand new Apple ID verification code on one in all your different gadgets.

8. In System Preferences, check in along with your Apple ID and your password adopted by the newest verification code.

Rationalization

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

This conflicts with Apple’s normal movement for older gadgets. 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.

This can be 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 aim to check in twice in a row, and Messages can solely try and check in 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 at least one sign-in try per half-hour, and Apple would not appear to thoughts that we’re utilizing the code in a special app from the place we requested it.
