    • Antes de iniciar este procedimiento, debes desactivar la función de arranque automático de tu Mac. El arranque automático se enciende en tu Mac cuando abres la tapa y puede activarse accidentalmente durante el desmontaje. Utiliza esta guía para desactivar el arranque automático.

    • Si tu MacBook está ejecutando Big Sur v11.1 o posterior, puede que no funcione la desactivación del arranque automático. Puedes proceder normalmente, pero asegúrate de desconectar la batería en cuanto estés dentro.

    • Apaga completamente y desenchufa tu MacBook Air antes de empezar. Cierra la pantalla y pon toda la portátil boca abajo.

    • Usa un destornillador P5 Pentalobe para quitar los siguientes seis tornillos :

    • Dos tornillos de 7.9 mm

    • Dos tornillos de 7.1 mm

    • Seis tornillos de 2.6 mm

    If the first thing you do is disconnect the battery, is it really an issue if you don’t (or can’t) disable auto-boot?

    I agree, why disable Auto-Boot when the lid is closed and the battery is disconnected immediately? – I've never had an issue since 2016 when the feature was introduced.

    On my machine, the longest two screws were in the corners, while the other two long screws were in the middle. Perhaps previous service in the past had them replaced into the wrong place? In any case, the longest screws do seem to fit in either place. I guess 0.8mm is not very much of a difference. Seems like poor design if they could have used one size of screw.

    • Pon tus dedos entre la pantalla y la caja inferior y tira hacia arriba para sacar la caja inferior de la computadora.

    • Remueve la caja inferior.

    Das geht etwas schwer, da das Unterteil mittig noch von 2 Druckverschlüssen gehalten wird.

    • Quita la cinta que cubre el conector de la batería lo suficiente como para revelar el conector que hay debajo.

    • Utiliza un spudger para deslizar el conector de la batería en paralelo a la placa lógica y sacarlo de su zócalo en la placa lógica.

    Before the battery can be fully disconnected, the battery disconnect button needs to be held down. There is a gold button just above the battery socket, along with a small LED much like the 12” machines. Once this has been held down and the LED has switched off it is safe to remove the battery.

    Aaron Dalziel -

    This seems like an important step?

    maccentric -

    Also, seems like this should be done after the battery is disconnected, not before? Otherwise, wouldn’t the battery re-charge it?

    maccentric -

    What if the white LED dosent light up after pressing the yellow button again?

    I just performed this repair on my late 2018 mac air. I did click the gold button but saw no LED illuminated or otherwise. Question- after reassembly does the button get pressed again to connect the battery? Please clarify if this button is to be pressed and if it needs pressing again after the repair.

    All said - I pressed again after the battery connector clicked, assembled the back and all worked perfectly. The original issue was one dead port (no charge, no communication). The battery charge lightening bold icon was acting funny too. Genuis bar guy in Naperville said it was likely a logic board too. But it was not. The port was apparently confusing the logic board with regards to the charge function. Thanks Adam for saving me $440 and sending my computer back to Apple. I am 71 yrs young - who says an old dog can’t learn new tricks with good training!!

    I didn't see Aaron's comment before completing the battery replacement. Afterwards, the computer would not turn on despite multiple SMC reset procedures. Upon double-checking the comments I see the importance of pressing the gold button. I pressed the gold button before disconnecting the new battery, then pressed it again after reconnecting for good measure. Computer booted!

    It would be good of iFixit to add this important step as most people probably don't open up every single comment on (seemingly) simple steps.

    Corey Matsumoto -

    Seconding Corey's comment. If paid more attention to the comment section, I would have avoided 15-30 minutes of panic. (BTW I did not notice any LED, but the golden button was easy to find).

    • Inserta la punta de un spudger bajo uno de los cables de la antena cerca del conector.

    • Levanta directamente para desconectar el cable.

    • Repite lo mismo con el otro cable de antena.

    As you are putting everything back together, it is a bit wonky trying to reconnect these antenna. Patience is necessary and it helps if you reshape the cables so that the cables are like the picture.

    • Levanta la barra de la antena hacia arriba y fuera de la caja. Ten cuidado de no enganchar la barra de la antena en ningún cable o conector.

    • Es posible que encuentre resistencia en los clips que están en el centro de la barra de la antena y que la sujetan en la caja. Puedes tirar con fuerza sin dañar nada siempre que tires hacia arriba, perpendicularmente a la caja.

    • Remueve la barra de antena.

    Tip: keep the six big lid anchor screws in place until after you remove the antenna bar. You may have to use your plastics spudger to wedge underneath the vents and get leverage off the underside of the lid along the hinge area. I also had to remove the Logicboard so I could get the plastic spudger underneath the antenna bar and lift it up. It felt like it was going to break. Did not want to have to remove the logic board, but seemed that was the only way I could get underneath and pry the antenna out.

    Felt like I was going to break it! It will come out but it requires patience and light touch

    Lamar's suggestion to view the video is excellent. Though I saw it only in arrears, it was quite valuable. I found a spudge, used to GENTLY pry both side first, then begin lifting on your right side (with back of laptop facing you) while gently twisting slightly inward to do the trick.

    Probably the worst moment in this repair.
