Before you install
Confirm that both Macs are running macOS 12.3 or later. The two Macs must be connected over the same Wi-Fi network, the same Ethernet network, or a direct Thunderbolt connection using Thunderbolt Bridge.
macOS may ask you to confirm that you want to open an app downloaded from the internet.
If the download does not begin automatically, use the download button above again or open the DMG link directly.
