REPAIR TIME & SKILL LEVEL:

This repair is estimated to take about 2 to 3 HOURS to complete and is of INTERMEDIATE difficulty, requiring careful handling of delicate components and familiarity with internal MacBook layouts.

STEPS:

Tools You Need

For this repair, you will need a suction cup for lifting the bottom case, a Pentalobe screwdriver for the base screws, a T5 and T3 Torx screwdriver for internal components, a PL1 screwdriver for the Wi-Fi vent module, a plastic spudger for safely disconnecting flex cables, and tweezers to assist with delicate cable routing and alignment.

---

Remove the Bottom Case

• Flip the MacBook over and remove six pentalobe screws: two long ones at the top and four shorter ones at the bottom.
• Use a suction cup or your fingers to lift the bottom case.
• Push the top case away and pull the bottom case toward yourself to release the clips and sliding fingers.

---

Disconnect the Battery

• Use a plastic spudger to unplug the battery management unit flex cable.
• With a T5 screwdriver, remove the pancake screw securing the jumper from the logic board to the battery board.
• This safely cuts off battery power so the unit can be worked on.

---

Remove Wi-Fi Vent and LCD Screws

• Using the same T5, remove four screws securing the Wi-Fi vent module and LCD board to the top case.
• Before removing the final screw, unplug the Wi-Fi antenna cables.
• Remove the bracket that holds the antennas in place.

---

Disconnect LCD Proximity Sensor

• Switch to a T3 screwdriver and remove two screws from the LCD proximity sensor.
• Unplug the sensor which tells the MacBook when the lid is closed or open.
• Set it aside carefully for reinstallation later.

---

Remove LCD Hinge Covers

• Still using the T3 screwdriver, remove four screws holding the hinge covers.
• Carefully lift and remove the hinge covers from the top case.
• These expose the internal mounting screws of the LCD.

---

Remove LCD Bungee Screws

• Using T3, remove four long screws holding the bungees in place.
• These provide hinge tension and stability when opening/closing the display.
• Screws may stay lodged even when loose; remove carefully.

---

Disconnect LCD Display Connector

• Remove four T3 screws securing the LCD display connector bracket.
• The top two screws are shorter; bottom two are longer.
• This step ensures the display cable doesn’t get kinked or damaged.

---

Remove Wi-Fi Vent Screws

• Switch to a PL1 screwdriver and remove all screws on both sides of the Wi-Fi vent module.
• These help detach it completely from the top case.
• Set them aside in order for easy reassembly.

---

Remove LCD Assembly

• Unscrew six T8 screws—three on each hinge location.
• Use a plastic spudger to remove the Wi-Fi vent module and unplug the LCD display connector.
• Open the MacBook and lift off the damaged LCD assembly.

---

Prepare New LCD Assembly

• Set aside the old LCD and place the new one on your work surface.
• Open the hinges slightly to slide the top case onto the new display.
• Hold the hinges while closing the unit to avoid damaging the top case.

---

Secure LCD to Top Case

• Reinstall the six T8 screws to secure the LCD to the top case.
• Make sure they’re tight—loose screws can cause the display to fall closed.
• Confirm hinge alignment before proceeding.

---

Reconnect LCD Proximity Sensor

• Plug the LCD proximity sensor back in immediately to avoid forgetting later.
• Use the T3 to reinstall its bracket.
• Ensure the hook on the logic board is correctly aligned before fastening.

---

Reinstall LCD Bungee Screws

• Install the four T3 screws that hold the LCD bungees.
• They may take some alignment; they will click into place.
• Don’t force them—patience is key.

---

Reinstall Wi-Fi Vent Module

• Place the vent module back into position.
• Use tweezers to feed the antenna cables through the cutout and up into the correct path.
• Align the bracket carefully and make sure all cables pass through properly.

---

Plug in Wi-Fi Antennas and Secure Bracket

• Connect all Wi-Fi antennas in place.
• Secure the bracket using the T5 screwdriver.
• Also secure the LCD board and vent module to the top case with T5.

---

Secure LCD Display Connector

• Plug in the LCD display connector.
• Use four T3 screws (2 short at the top, 2 long at the bottom) to resecure the bracket.
• Ensure the cable sits cleanly beneath the bracket to prevent pinching.

---

Reinstall Touch Bar Bracket

• Use two T3 screws to reinstall the bracket holding the touch bar connector and LCD proximity sensor.
• Hook the bracket into place before tightening the screws.
• Double-check alignment before finalizing.

---

Secure Wi-Fi Vent Screws

• Take your PL1 screwdriver and reinstall the many screws on the vent module.
• Start from the edges and work inward.
• Tighten all screws evenly.

---

Reattach LCD Hinge Covers

• Place hinge covers back over the hinge areas.
• Secure them with four T3 screws.
• These finalize the exterior appearance and protect internal hinge hardware.

---

Reconnect Battery

• Use the T5 to screw the pancake jumper back in place.
• Reconnect the battery management unit flex cable.
• Ensure the cable is seated properly to avoid charging issues.

---

Power On and Test

• Plug in a charger and power on the MacBook.
• Confirm display functionality and battery charging.
• Verify the proximity sensor by opening/closing the lid and observing fan spin down.

---

Reinstall Bottom Case

• Line up one corner slightly off the edge.
• Push down and slide the case forward to engage the vent fingers.
• Install the two long pentalobe screws at the top and four shorter ones at the bottom.

---
