One of my favorite macOS Tahoe 26 and iOS 26 features is the ability to set your Mac to automatically join your iPhone hotspot. With this feature, your Mac can seamlessly switch to your iPhone’s personal hotspot when no Wi-Fi network is available. For times when you are on the move, working remotely, or dealing with a patchy home Wi-Fi connection, it can prove to be very helpful.
While this new add-on works like a charm, some iDevice users have complained that it’s malfunctioning. If it’s also gone off the track for you, this detailed guide with the proven fixes is for you.
Fix Mac Not Joining iPhone Hotspot Automatically in iOS 26 & macOS Tahoe 26
From the malfunctioning iPhone Hotspot to a random iOS/macOS software bug to a wrong configuration, there could be multiple reasons why your Mac is refusing to auto-join your iPhone’s personal hotspot.
1. Ensure Auto-Join Hotspot Is Enabled
The first step is to double-check whether you’ve actually turned on the Auto-Join option.
- On your Mac, click the Wi-Fi icon at the top-right corner and choose Wi-Fi settings.
- Scroll down and find the Ask to Join Hotspots section.
- Click the dropdown menu and set it to Automatic.
If it’s already set to “Never” or “Ask,” your Mac won’t auto-connect to your iPhone’s hotspot.
2. Keep iPhone and Mac Signed in to the Same Apple ID
Auto-Join relies heavily on Apple’s Continuity framework. That means your iPhone and Mac need to be signed in with the same Apple ID.
- On your iPhone, head to Settings > Apple ID (your name).
- On your Mac, click the Apple menu () > System Settings > Apple ID.
- If you are using the same Apple ID everywhere, sign out of your Apple ID and sign back in.
If the accounts don’t match, sign in with the same Apple ID on both devices. This ensures smooth hotspot handoff.
3. Enable Wi-Fi and Bluetooth on Both Devices
The feature won’t work if Wi-Fi or Bluetooth is disabled. They’re required for device discovery and connection.
- On your iPhone, swipe down to access Control Center, then make sure Wi-Fi and Bluetooth are enabled.
- On your Mac, click the Control Center icon and ensure both toggles are switched on.
It may sound simple, but many connection issues boil down to this step.
Note: Should the issue persist, turn on/off the Airplane mode to refresh the connection. Also, ensure that your iPhone is connected to a strong and stable cellular connection.
4. Keep Your iPhone Hotspot On and Visible
Sometimes, your iPhone’s hotspot may not broadcast properly.
- On your iPhone, go to Settings > Personal Hotspot.
- Toggle on Allow Others to Join.
- Make sure your iPhone has a stable mobile data connection.
Even though Auto-Join should wake up the hotspot automatically, manually toggling it once often helps reset the connection.
5. Forget and Reconnect to the Hotspot
If your Mac has previously connected to the hotspot but refuses to auto-join, the saved settings might be corrupted.
- On your Mac, go to System Settings > Wi-Fi.
- Under Known Networks, find your iPhone’s hotspot.
- Click the More (…) button and choose Forget This Network.
- Reconnect manually once, and then re-enable Auto-Join.
This often resolves persistent connection bugs.
6. Check Family Sharing Settings
macOS Tahoe 26 supports Family Sharing Hotspot Access, meaning you can allow family members to connect automatically. If this isn’t working, recheck the settings.
- On your iPhone, go to Settings > Family > Family Sharing.
- Ensure hotspot sharing is enabled for the selected family members.
Then, on your Mac, test by disconnecting Wi-Fi and see if it automatically picks up the family member’s hotspot.
7. Restart Both Devices
The classic fix still works wonders. Restart your Mac and iPhone to refresh system processes. Sometimes, temporary glitches stop auto-join from working.
8. Update macOS and iOS
Since this is a fairly new feature, Apple may patch bugs through updates.
- On Mac: Apple menu > System Settings > General > Software Update.
- On iPhone: Settings > General > Software Update.
Install the latest version to ensure compatibility and fix known issues.
9. Reset Network Settings (Last Resort)
If nothing else works, resetting network settings can resolve deeply buried issues.
- On iPhone: Settings > General > Transfer or Reset iPhone > Reset > Reset Network Settings.
- On Mac, launch Finder and head over to – /Library/Preferences/SystemConfiguration/
- After that, locate and move these files to the Trash:
com.apple.airport.preferences.plistcom.apple.network.identification.plistcom.apple.wifi.message-tracer.plistNetworkInterfaces.plistpreferences.plist- Once you have trashed these files, restart your Mac to recreate fresh network configuration files.
Keep in mind that it will wipe saved Wi-Fi and hotspot connections, so reconnect everything afterward.
Wrapping Up
And that’s about it, folks! Auto-Join iPhone Hotspot feature in macOS Tahoe 26 is a real convenience when it works properly. If your Mac isn’t auto-joining, try enabling the setting, ensuring the same Apple ID is in use, and keeping Wi-Fi/Bluetooth turned on. In many cases, a simple network reset or software update clears up the problem.
By following the steps above, your Mac should once again connect seamlessly to your iPhone’s hotspot whenever Wi-Fi isn’t available—keeping you online without interruptions.
