Fire damages MacBook Air A2337

You should be able to access the data using a wired external keyboard and target disk mode. Connect a wired keyboard to the system using one of the USB-C ports, then power on the computer while holding the T key on the wired keyboard. Continue to hold the key until you see the Thunderbolt icon appear on the screen. You can then connect a Thunderbolt cable to the damaged computer and to a working computer, and the internal drive of the damaged computer should show up as an attached external drive on the working computer.
