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 iOS5 or later or iPadOS 13 or later.

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.
