This guide will show you how to replace the logic board.

  1. Power down your Mac mini, disconnect all of the cables, and flip it over. Insert the Jimmy into the crack between the aluminum top housing and the plastic lower housing.
    • Power down your Mac mini, disconnect all of the cables, and flip it over.

    • Insert the Jimmy into the crack between the aluminum top housing and the plastic lower housing.

    • The Jimmy should reach a stop about 3/8" down.

  2. Gently bend the Jimmy outwards to pry the crack open a little larger and lift the lower housing up a small amount. There are several plastic clips on the lower housing that fit into a channel in the aluminum top housing. Your goal is to use the Jimmy to push these clips inward enough to free them from the channel, while gently pulling up on the lower housing.

  3. Once you have the first side free, rotate the Mac mini and start prying up on the front edge. Use the same prying motion to both bend the clips inward and lift the lower housing up out of the top housing.

    • Flip the Mac mini back over and lift the top housing off of the lower housing.

  7. In the next few steps you will be removing the AirPort and Bluetooth antennas (shown in red) from the internal frame. Be very careful, as breaking the brackets will require replacing the internal frame.
    • In the next few steps you will be removing the AirPort and Bluetooth antennas (shown in red) from the internal frame. Be very careful, as breaking the brackets will require replacing the internal frame.

    • We will first remove the AirPort antenna, located in the lower left corner of this picture.

  8. Slightly squeeze the two retaining arms toward each other and lift the AirPort antenna off its post. Squeezing the two posts excessively will surely break them off the internal frame. Work delicately.

¿Alguien sabe como diagnosticar que el problema es la tarjeta madre? El led interno 601 está siempre prendido pero el led602 parpadea dos veces cuando le aprieto el botón de encendido. Y bueno, no prende la mac.
