    According to this page, the 8 screws are not identical.

    Can anybody tell me where each kind of screw is supposed to go?

    They are all 100% Identical. You were probably looking at a different model, or Apple has entered the wrong information... Hey, It happens...

    The screws on the Late 2009 are identical. The blue lock compound might make tightening some require a little more effort.

    thanks again mick van aar, perth western aus.

    The A1342 will take up to 16 GB of RAM, however, there are only two RAM slots, so use two 8-GB RAM modules. Other World Computing (OWC) is a great reference source for info on exactly which RAM to use with which model; prices are usually much better on EBay though. Add an SSD from OWC and your machine will really scream!

    I hope that helps!

    Gregoire is right. The 8 screws are absolutely NOT identical, I’m looking at them right now, weeowey weeowey.

  2. La struttura del case inferiore è in alluminio con rivestimento in gomma. Durante la rimozione, non piegare eccessivamente l'alluminio, poiché eventuali deformazioni permanenti causerebbero problemi di tolleranze dopo il riassemblaggio.

    • Sollevare leggermente il case inferiore in prossimità dell'apertura della presa d'aria.

    • Continuare a far scorrere le dita fra i case superiore e inferiore finché quello superiore non si sgancia dalle levette di fissaggio.

    • La posizione di queste tre levette è indicata nella terza immagine.

    Do the retaining clips have to be re-engaged when replacing the lower case?

    John Morley - Replica

    Answering my own question, the clips re-engage when the lower case is correctly positioned. You can help them by gently pressing the lower case with your thumbs midway along the two short sides. When everything is correctly aligned the eight screw holes line up.

    John Morley -

    Rather than running your fingernail down the sides to free up the retaining clips, I found that using an old credit card, inserted about 1/4”, to run along the left and right side popped those end retaining clips right off with no problem. You may need to twist the card slightly when in the middle area to help pop those off.

    • Per precauzione, suggeriamo di scollegare il connettore della batteria dalla scheda logica per evitare eventuali scariche elettriche. Il passaggio è facoltativo.

    • Mediante l'estremità piatta di un inseritore, sollevare il connettore del cavo della batteria dal connettore femmina sulla scheda logica tirandolo verso l'alto.

    • Potrebbe essere più semplice utilizzare le unghie per sollevare il connettore da entrambi i lati.

    you do not need to remove the battery when replacing the hard drive or ram

    beware not to lift the connector to close of the angle, as the picture suggest it. It might broke the angle. Attack by the middle.

    Not necessary?

    hikkymemo - Replica

    Be careful of the corner of the battery cable connector when trying to pry it off with the spudge. I knocked the corner of mine. No operational impact but was not very pleasing!

    jljordanweb - Replica

    Not necessary, but a good idea, so as to avoid any spurious charges going through the boards...

    svenaustx - Replica

    @Svenaustx - What could happen if not removing this battery? Worst case? Not a geek on this but did change RAM on my Macbook Pro "15. Can't remember disconneting the battery back then. Shouldn't it be sufficient shutting the Mac off and ensure it has been used for an hour or so before replacing RAM?

    Allan Clarke -

    i used a metal pry and noticed some sparking when i disconnected the battery. replaced ram. now it wont turn on. did i fry it?

    • Sganciare le linguette sui lati del chip, premendole contemporaneamente in senso opposto al modulo stesso.

    • Queste linguette bloccano il chip in posizione. Sganciandole, il chip "salterà" fuori.

    Aggiungi Commento

    • Dopo aver sganciato il chip di memoria RAM, estrarlo dal relativo connettore.

    • Ripetere la procedura in presenza di un secondo chip di memoria RAM.

I have been running 2 x 4gb chips for the last two months in my unibody white late 2009 macbook with no probs. The only difference from the standard ram chips is a massive speed boost!

alex - Replica

Hi I'm currently installing 16gbs of ram, that is supported by my Macbook 2010 White unibody, however the mac is not reading the full amount installed. i have gotten 10gbs working, by installing one of the new 8gbs sticks, and the old 2gb. Both of the new sticks of Ram have been tested, by simply swopping them out with each other, but when combine the full 16gb sends a error code, 3 beeps with a 5 sec in between. Both ram slots work, all four sticks of ram work, the two 8gb and the old two sticks of 2gb, and computer runs right now at 10gb, so there is proof that it is supported. please help me, i am stuck.

skyler hall - Replica

You have two different types of ram there... One cannot be read by the Mac book for some reason because of the speed or type.

theloo32 -

Hey Skyler, I'm having the same issue. It appears that if you have at least one DIMM of 1066MHz RAM, the machine will be able to boot and clock-down faster RAM so that both DIMMs are running at this MacBook's maximum 1066MHz speed. I suspect that because both of my upgraded DIMMs are faster than 1066MHz (1300MHz), it is preventing the machine from being able to boot, and it's subsequently unable to remedy the RAM speed discrepancy. In my case, I get a single beep every 5 seconds when trying to boot which means "No RAM Installed"

The solution would be to return the faster memory and buy 1066MHz speed RAM, although now-a-days that's more expensive than buying 1300MHz or 1600MHz RAM when you're looking for 16GB. I guess you can also leave the mismatch DIMMs (10GB) if you need to, but it's definitely not optimal.

My white 13" MacBook Unibody Late 2009 A1342 updated to OS X 10.11.6 (El Capitan) now runs 8GB (2x4GB) of DDR3 1333 SODIMM taken from my Lenovo Y570 laptop. The MacBook already used an SSD, but is even quicker now. Here are some screenshots from the MacBook:

Hopefully any brand of 2x4GB DDR3 1333 SODIMM will work for you...

Note that it has to be 1.5 volt DDR3 RAM, not 1.35 volt DDR3L.

Has anyone tried 16 gb in the late 2009 (white) MacBook?

Scott Davidson - Replica

What type of ram should i use as i tried 2 sticks of 2gb in it and it doesnt work. Although, if i just put the 1gb which was original from apple and 1 stick of the 2gb it will work…it just wont work the two 2gb sticks together and what is the max ram please.

Alfie Johnson - Replica

You are right. This was easy. The hardest part was removing and replacing the eight 4 mm Phillips screws securing the lower case to the MacBook.

My MacBook Unibody Model A1342 now has 16GB of OWC Memory.

Thanks Walter!
