Fix iPhone messages not forwarding to Mac on macOS Tahoe

Breaking: iPhone Texts Won’t Forward to Mac on iOS 26 / Tahoe 26 — What You Need to Know and Do

A widespread hiccup is affecting iPhone users after updating to iOS 26 and macOS tahoe 26. SMS, MMS, and RCS messages that should appear on Mac and other Apple devices aren’t syncing automatically. Tech teams are tracking the issue as users report mixed success with the built‑in sync options.

What’s causing the delay in message syncing?

The two built‑in pathways for cross‑device messaging are Contacts and Cloud sync. First, Messages in iCloud backs up SMS, MMS, RCS, and iMessages to iCloud for access on iPhone, iPad, Mac, and Vision Pro. Second, Text Message Forwarding routes SMS, MMS, and RCS to linked devices. If one of these features isn’t operating correctly after the update, messages may not show on your Mac or iPad as expected.

Users report the issue appears most often after upgrading to iOS 26 and macOS Tahoe 26. When the forwarding becomes temporarily unlinked, messages can fail to surface on non‑iPhone devices despite being enabled.

Two reliable routes to keep messages in sync

Option	How It Works	Pros	Cons
Messages in iCloud	Backs up all iPhone messages to iCloud and syncs across iPhone, iPad, Mac, and Vision Pro.	Unified history across devices; automatic cross‑device availability.	Consumes iCloud storage; may lag if iCloud sync is slow or disabled on a device.
Text Message Forwarding	Forwards SMS, MMS, and RCS from iPhone to linked iPad, Mac, or other devices.	Fewer iCloud storage concerns; works even if Messages in iCloud isn’t enabled.	Requires active network on all devices; can be flaky if device pairing or accounts aren’t in sync.

Checklist: Quick checks to restore sync

1. Verify all devices use the same Apple ID on iOS 26 and macOS Tahoe 26. If not, sign out and sign back in with the primary account.
2. Ensure all devices are connected to the Internet (Wi‑Fi or cellular).Disable vpns if they’re in use.
3. Restart every device to clear temporary glitches and allow a full re‑sync.
4. Update iPhone, iPad, and Mac to the latest available builds for iOS 26, iPadOS 26, and macOS Tahoe 26.
5. Confirm Messages in iCloud or Text Message Forwarding is enabled. You don’t need both; one is sufficient if it’s functioning reliably.

How to enable Messages in iCloud

On iPhone or iPad

1. Open Settings and tap your Apple ID at the top.
2. Tap iCloud > Messages.
3. Enable Use on this iPhone (or iPad) and, if needed, tap Sync Now when the last sync date is stale.

On Mac

1. Open System Settings and click your Apple ID > iCloud > Messages.
2. Turn on Use on this Mac and use Sync Now if required.

How to enable Text Message Forwarding

1. On your iPhone, open Settings and go to Messages.
2. Tap Text Message Forwarding.
3. Enable the switch for Mac and iPad where you want to receive iPhone SMS, MMS, and RCS messages.

Refreshing iMessage: a proven workaround

For many users, a specific refresh sequence restores cross‑device messaging. Follow these steps carefully:

1. On iPhone, go to Settings > Apps > Messages > Send & Receive.
2. Deregister the iPhone’s number from iMessage by removing the checked phone number and signing out any non‑main email addresses. Then turn off iMessage for about 30 seconds.
3. Return to the previous screen, confirm the number has been deregistered, and observe that the device list updates on your Mac.
4. Reactivate iMessage on the iPhone. The Send & Receive section should show only your Apple ID email address.
5. Look for a confirmation alert across iPhone, iPad, and Mac that a new device has been added to your iMessage account.
6. Re‑register the phone number in Send & Receive,and wait for the process to finish.
7. With iMessage refreshed, verify Internet connections and ensure the iPhone number and Apple ID email appear in Mac iMessage settings.

After completing the refresh, ask a friend to send an SMS or RCS to your number and lock your iPhone. The inbound text should appear on the Mac as well, with you able to reply directly from the Mac notification.

When nothing else works

If the above steps fail, sign out of iCloud on one or more devices and sign back in. This can resolve lingering account synchronization issues that may have been introduced by the latest software update.

Evergreen takeaways for reliable messaging

Maintain a consistent Apple ID across devices, keep devices updated, and ensure stable internet connections. If storage is tight on iCloud,Text Message Forwarding offers a viable choice,but users should monitor reliability and consider freeing space to improve the iCloud route.
