Connecting via Target Display Mode (Legacy)

Important Note: Target Display Mode is only available on specific iMac models. Check Apple’s documentation to ensure your iMac supports this feature.

Ensure both your iMac and MacBook are powered on.
Connect the two devices using a Thunderbolt or Mini DisplayPort cable.
On your iMac, press Command (⌘) + F2. The iMac screen should switch to displaying the MacBook’s screen.
To exit Target Display Mode, press Command (⌘) + F2 again on your iMac.

Connecting via AirDrop

AirDrop is the simplest way to transfer small files.
