Outdated software on either the MacBook or the iPhone can introduce compatibility issues. Apple frequently releases updates that fix bugs and improve iMessage functionality. Running outdated versions may prevent messages from syncing correctly.

Incorrect settings within the Messages app or iCloud can also cause syncing problems. For example, if the “Messages in iCloud” feature is disabled on any device, messages may not update across all platforms.

Other causes include:

  • Problems with the Apple ID authentication or two-factor authentication.
  • Temporary server-side issues on Apple’s iCloud service.
  • Corrupted cache or preferences files related to the Messages app.
  • Restrictions or parental controls limiting iMessage usage.
