You can sync your Mac and device when they’re connected over same Wi-Fi network. 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. Whenever your device connects to your Mac over Wi-Fi, you can select it in the sidebar and sync it. (You can turn on automatic syncing if you want.) Your device must have iOS 5 or later or iPadOS 13 or later.
See Intro to syncing your Mac and your devices.
- Connect your device to your Mac using a USB or USB-C cable.
- In the Finder
on your Mac, select the device in the Finder sidebar.
If you connect your device to your Mac using a USB cable and don’t see the device in the Finder sidebar, see If your device doesn’t appear in the sidebar.
- Click General in the button bar.
- Select the “Show this [device] when on Wi-Fi” tick box.
- Use the button bar to turn on and select sync settings.
- Click Apply.
Whenever your device connects to your Mac, the device’s icon appears in the sidebar. Select the device in the Finder sidebar to view or change syncing options.
Important: If you don’t see your device in the sidebar, choose Finder > Settings, then select the CDs, DVDs and iOS Devices tick box.
You can choose to sync your Mac and your device automatically whenever you connect them. See Turn automatic syncing on or off on Mac.
Before disconnecting your device from your Mac, click the Eject button 
in the Finder sidebar. The device icon disappears but Wi-Fi syncing remains turned on. The icon reappears automatically the next time your Mac and device are connected to the same Wi-Fi network.
Note: To restore your iPhone, iPad or iPod touch and revert it to its factory settings, you must connect the device to your Mac using a USB or USB-C cable.
Syncing over Wi-Fi is slower than syncing over a cable. If you connect a device to your Mac while the device is syncing over Wi-Fi, syncing continues over the cable. If you disconnect the device’s cable from the Mac while syncing, syncing stops, even if Wi-Fi syncing is on. Syncing resumes when you reconnect the device using a cable or over Wi-Fi.
