iPhone to MacBook Pro WiFi Syncing problems

Apple discovered a vulnerability with Wi-Fi sync that would allow a “bad actor” to initiate a backup to a computer that they had local or remote access to, so the added the requirement that the phone’s passcode be entered on the phone to back it up. I imagine they are looking for a better solution long term, but for now that’s the reason. Here’s more detail→https://imazing.com/blog/ios-backup-passcode-prompt

Hi BaliMac,

You started from a great resource: Sync content between your Mac and iPhone, iPad or iPod touch over Wi-Fi

In the guide it does state "To set up Wi-Fi syncing, first connect your device to your Mac using a USB or USB-C cable. You then turn on Wi-Fi syncing and choose the settings you want."

If you've first connected with a cable to ensure your settings are correct, test the steps below found in the article here: Use the Finder to sync your iPhone, iPad, or iPod with your computer

"Sync your content using Wi-Fi

After you set up syncing with the Finder using USB, you can set up the Finder to sync to your device with Wi-Fi instead of USB.

1. Connect your device to your computer with a USB cable, then open a Finder window and select your device.
2. Select “Show this [device] when on Wi-Fi."
3. Click Apply.

When the computer and the device are on the same Wi-Fi network, the device appears in the Finder. The device syncs automatically whenever it's plugged in to power."

If you're still asked for a passcode to sync via Wi-Fi, reach out to Apple Support directly to further assist.
