Removal
Note: If you’ve already completed the removal steps, skip to reassembly.
Position the housing with the logic board facing up.
Use the 10–34 Ncm adjustable torque driver and 3IP 25 mm bit to remove three 3IP screws (923-12078) from the Wi-Fi antenna.
Use the teal torque driver and 3IP 44 mm half-moon bit to remove three 3IP screws (923-11029) from the antenna grounding clips on the logic board.
Use the antenna tool to lift the ends of the three antenna coaxial cables off the connectors.
Use the flat end of the black stick to lift the end of the speaker cable off the connector.
Use ESD-safe tweezers to peel the polyester film tape off the display backlight flex cable connector. Save the tape for reassembly.
Pinch the sides of the end of the display backlight flex cable and slide it out of the connector. Then remove the display backlight flex cable from the housing and save it for reassembly.
Use the flat end of the black stick to press and hold the “PUSH” button on the zero-insertion force (ZIF) audio board and power button connector. While pressing the button, slide the end of the audio board and power button flex cable out of the connector. Then press and hold the "PUSH" button on the ZIF microphone connector and slide the microphone flex cable out of the connector.
Pull the tab to flip up the locking bar on the camera and embedded DisplayPort (eDP) flex cable (1). Slide the end of the camera and eDP flex cable out of the connector (2). Then remove the camera and eDP flex cable from the housing and save it for reassembly.
If you’re repairing an iMac (24-inch, M6, Two ports), skip to step 11. If you’re repairing an iMac (24-inch, M6, Four ports), pull the tab to flip up the locking bar on the logic board end of the high-speed flex cable (1). Slide the end of the high-speed flex cable out of the connector on the logic board (2). Then continue to the next step.
Use the 2.5 mm hex nut driver to remove 2.5 mm hex nut screws from the logic board as shown.
iMac (24-inch, M6, Two ports): Six screws (923-11028) (1)
iMac (24-inch, M6, Four ports): Five screws (923-11028 (1)
Four screws (923-11025) (2)

Move the antenna coaxial cables and flex cables out of the way as you tilt forward the logic board (1). Then use the flat end of the black stick to release the Wi-Fi antenna coaxial cable from the antenna grounding clip on the housing (2).
Use the black stick to gently peel the Wi-Fi antenna coaxial cable tape from the housing in the areas shown.
Lift the Wi-Fi antenna coaxial cable out of the channel in the speaker.
Remove the Wi-Fi antenna from the housing.
Note: You may need to release the adhesive between the microphone flex cable and the housing to remove the Wi-Fi antenna coaxial cable.
Reassembly
Position the Wi-Fi antenna in the housing. Set the torque value on the 10–34 Ncm adjustable torque driver to 10 Ncm. Use the adjustable torque driver and 3IP 25 mm bit to reinstall three 3IP screws (923-12078) into the Wi-Fi antenna.
Route the Wi-Fi antenna coaxial cable as shown.
Important: The Wi-Fi antenna coaxial cable must be routed under the microphone flex cable and audio board and power button flex cable as shown.
Press along the length of the Wi-Fi antenna coaxial cable tape to adhere it to the housing in the areas shown. Then use the flat end of the black stick to press the tape to adhere it to the housing as shown.
Route the Wi-Fi antenna coaxial cable into the speaker channel.
Press the tape above the speaker to adhere it to the housing.
Move the antenna coaxial cables and flex cables out of the way as you tilt forward the logic board (1). Then press the Wi-Fi antenna coaxial cable into the antenna grounding clip on the housing (2).
Position the logic board in the housing. Then use the blunt end of the antenna tool to press the ends of the three antenna coaxial cables to the connectors.
Use the teal torque driver and 3IP 44 mm half-moon bit to reinstall three 3IP screws (923-11029) into the antenna grounding clips on the logic board.
Use the 2.5 mm hex nut driver to reinstall 2.5 mm hex nut screws into the logic board as shown.
