Mac not recognizing iPhone after iOS update

One of us is not understanding the other.

In the year prior to updating iOS on my iPhone last night, my 2023 Mac mini M2 and my iPhone 16e, were happily paired, and the iPhone showed up in the Mac's Finder sidebar. AFTER updating iOS last night, that is no longer the case. And, after going through the various steps to solve the issue, and even though my iPhone says it is discoverable, and it now (finally) shows my Mac mini as available Bluetooth devices, when I attempt to pair the two devices, I am told "Pairing Unsuccessful:" my Mac mini M2 is "not supported."

NOT SUPPORTED? Everything was fine until this iOS update. As a Mac user since 1989, it would appear "Plug and Play" has died. Seriously: I am confused. Somebody please help me make sense of this.

As den.thed told you, Macs and iPhones normally do not pair with each other over Bluetooth. Some Continuity features make use of Bluetooth, but not in that way. Same goes for iPhone management using the Finder. The "not supported" message you received would thus be entirely normal and expected.

You may be mistaking syncing over Wi-Fi for Bluetooth pairing. When you connect your iPhone to your Mac, using a USB cable, you can set up things so that the two can sync over Wi-Fi later. See: Use the Finder to sync your iPhone, iPad, or iPod touch with your Mac - Apple Support .

I would suggest connecting your iPhone to your Mac with a cable, and then re-checking the setting which the Apple Support article mentioned, to see if the update somehow switched it off. If the setting is turned on, and your Finder settings say to show iOS devices in the sidebars of Finder windows, and your iPhone and Mac are connected to the same Wi-Fi network, and it still doesn't work, then you could consider calling Apple Support and/or reporting a bug using Apple's feedback page.

To fix your iPhone 16e not appearing in Finder after an update, re-enable "Show this [device] when on Wi-Fi" while connected via cable, restart the AppleMobileDeviceProcess, or check for VPN/security software interference. The issue often stems from a handshake failure between updated software and trusted devices.

Recommended Troubleshooting Steps:

• Re-enable Wi-Fi Syncing: Connect your iPhone via USB, open Finder, click the phone, and ensure the "Show this [device] when on Wi-Fi" checkbox is selected in the General tab.
• Trust the Computer Again: On your iPhone, go to Settings > General > Transfer or Reset iPhone > Reset > Reset Location & Privacy. Unplug and replug the phone to see the "Trust This Computer" prompt.
• Check USB/Cable Integrity: The iPhone 16e should vibrate/chime upon connection. If not, the USB-C cable may be damaged or only support charging, not data, preventing Finder detection.
• Toggle WiFi/Bluetooth: Ensure both Mac and iPhone are on the same Wi-Fi network and Bluetooth is enabled on both, as Finder relies on these for wireless continuity.
• Restart Management Services: If the Mac still doesn't see it, try restarting the Apple mobile device services to restore connectivity.

If these do not work, restart your Mac in Safe Mode to check for third-party software conflicts.

I appreciate all the responses. But here's the thing: since buying the iPhone a year ago, it had always appeared in my Mac's Finder sidebar without being connected to the Mac by cable.

Yes. That would involve syncing over Wi-Fi, not Bluetooth pairing. Wi-Fi and Bluetooth are both wireless technologies, but they are not the same technology.

If Apple changed something, and that will no longer be the case, I'm fine with that. I just don't understand why there was no mention of a change. What did I know?

ALL of this would've been unnecessary if I'd known that iPhone will no longer appear in the Finder sidebar, but everything will still function as it had.

If the control for Wi-Fi syncing still appears when you connect the Mac and the iPhone via a cable, I would assume that Apple has not intentionally removed the feature, and that you are looking either at

• A simple change to the setting, which you can reverse, or
• A bug, which should be reported so that Apple knows to fix it

NOT SOLVED. After updating iOS, my 2023 Mac mini no longer "sees" my iPhone 16e. I checked settings, restarted both devices, and downloaded the software allegedly needed to correct this problem. But, after disconnecting the USB cable, the iPhone disappeared from my Finder sidebar, and it does not show up in Bluetooth settings with my other Bluetooth devices.

That is normal because the iPhone and Mac do not use the bluetooth connection for user activity.

Now i’m wondering if you were using some third-party app for syncing devices that was broken by the update.
