Sync content between your Mac and iPhone, iPad, or iPod touch over Wi-Fi
You can sync your Mac and device when they’re connected to the 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.
For more information about syncing, see Intro to syncing your Mac and your devices.
Connect your device to your Mac.
You can connect your device using a USB or USB-C cable or a Wi-Fi connection.
Click
in the Dock to open a Finder window, then 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 the Apple Support article If your computer doesn’t recognize your iPhone or iPad.
In the row near the top, click General.
Select the “Show this [device] when on Wi-Fi” checkbox.
Use the options across the top of the window 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 checkbox.
Before disconnecting your device from your Mac, click 
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.
You can choose to sync your Mac and your device automatically whenever you connect them. See Turn automatic syncing on or off.
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.
