Introduzione

Segui i passi in questa guida per cambiare o sostituire il disco rigido SATA nel iMac 21.5" Retina 4K (2017). Fai attenzione che, se stai aggiornando il tuo disco, per tenere i tuoi file e il sistema operativo dovrai clonare il tuo disco rigido esistente su quello che andrà a sostituirlo prima di procedere.

Alcune immagini in questa guida usano un iMac 2015, il quale ha solo delle minori differenze visive. Queste non influenzano la procedura di riparazione.

    • Con il cardine libero di muoversi, l'iMac sarà sbilanciato e la lavorazione risulterà difficoltosa. Le riparazioni saranno più rapide e facili con un cuneo di supporto per iMac, ma potranno essere completate anche senza di esso.

    • Se intendi usare il Cuneo di cartone di supporto dell'iMac di iFixit, segui queste istruzioni di assemblaggio per montarlo.

    • Prima di iniziare a lavorare sull'iMac, scollega il computer dall'alimentazione e tieni premuto il pulsante di alimentazione per 10 secondi per scaricare i condensatori dell'alimentatore.

    • Fai molta attenzione a non toccare i contatti dei condensatori o qualsiasi punto di saldatura esposto sulla parte posteriore dell'alimentatore. Maneggia la scheda tenendola solo dai bordi.

    The wedge is an extremely tight fit for this model. I was worried that the amount of force needed to use it as shown might damage the stand, so I used it with the long side down instead. It worked fine that way and didn’t need anywhere near as much force to insert.

    Here are a couple tips from me:

    1) Expose the adhesive to extreme temperatures. I did this by transporting my iMac in my car, screen-down on a piece of cardboard on a cold February morning (in Chicago). When I went to pick up the iMac, the screen practically fell off the chassis. I would have been distraught by this if I hadn’t already planned this replacement. So it was a happy accident.

    2) Remember to expell the residual power from the power supply by pushing the power button while the iMac is unplugged. This does NOT guarantee it’s safe to touch, but when I accidentally brushed the solder and exposed capacitors, I didn’t get shocked.

    Instead of using the wedge, I placed the iMac faced up with the top side (web cam) facing me while I ran the pizza roller around. It worked out great!

    There is no replacement glass for this model, it is part of the LCD and impossible to remove or replace- the entire LCD has to be replaced unfortunately if the glass is cracked or damaged. You will have to Google search for a replacement. Also be careful with some of the lock tight tork screws as I broke one of my screw mounts taking one out.

    Phil Tesone - Replica

    I used this service wedge but also found it a very tight fit. The same stabilization can be achieved by using a big rolled up towel.

    While this is a good instruction guide, I recommend to also look at OWC’s instruction video about drive installation, before starting the exercise. Those install videos are very detailed and useful.

    • Iniziare sulla parte sinistra del display, accanto al pulsante di alimentazione, inserire l'attrezzo per l'apertura dell'iMac nello spazio fra il pannello di vetro e il case posteriore.

    • Il perno sull'attrezzo per l'apertura dell'iMac impedisce di inserire la ruota troppo a fondo. Nel caso di utilizzo di un altro attrezzo, non inserirlo nel display per più di 0,95 cm, In caso contrario, si rischia di tranciare i cavi dell'antenna e provocare danni gravi.

    Don’t get too worried about starting exactly where the picture says. The glue is stronger in some parts so just start wherever is easier and then work slowly and patiently around in the direction shown.

    As this guide doesn’t cover replacing the adhesive strips, I found referring to the following was useful (noting that it’s not for the same model of iMac, so the modification they mention wasn’t necessary): Sostituzione strisce adesive iMac Intel 21.5" EMC 2544

    It is very easy to crack the glass in front of the LCD during this step. I used the guitar pick, maybe it was too thick… crack is just on the frame but anyway it is disappointing :(

    Nikolay - Replica

    This part of the exercise should be done with extreme patience. I took my sweet time with the opening tool, rolling it through the entire panel and enclosure gap over and over again, until I was very sure no parts were sticking together anymore. And when I thought I was I done, I decided to do it over again.

    Ernst - Replica

    You can "warm up" the adhesive before try to cut it with the tool using a hair dryer. Heat the edges for about a minute, keep moving it so you don't cause stress in the glass. Also the above note.. use the tool and then the cards. Do not use a guitar pick or other objects as the thickness will cause you to break the front glass, which is a bonded part of the display (expensive).

    • Utilizzare l'attrezzo come una taglierina per la pizza: ruotarlo lungo lo spazio per tagliare la schiuma adesiva al centro.

    • Effettuare sempre una pressione con l'impugnatura dietro il disco tagliente. Tirando, il disco potrebbe uscire dall'impugnatura.

    • Far scorrere l'attrezzo lungo il lato sinistro del display.

    If re-opening a screen that was opened and re-attached using iFixit’s adhesive strips, I would strongly recommend heating it first with an iOpener, heat gun or hair dryer. 20 minutes after attaching with the iFixit adhesive I tried to open it again with the pizza slicer to fix something and cracked the screen on the left-hand side.

    In this step can I cut along the display without make any damage to the front camera?

    arisnordico - Replica

    Hi! Actually - there is no need to cut the tape around the camera area - there is no tape to cut at all! And so, the way go is easy - just pass 10 mm to the left and to the right from camera and start cutting!

    P.S. Just did the whole procedure to replace a RAM and to add SSD on PSIe an hour ago! Seems to be different reading the instructions... you know - 2/10 and so on. But it's really not that hard, trust me. I'll give it 5/10.

    P.P.S. By the way there is one trick to pass the difficult steps. Any action which requires pulling smth (motherboard, speaker, power supply unit) from the narrow crack (or should i say - slit?) at the bottom of your Imac is really not so easy.

    And the trick is to first remove a thin metal stripe with some kind of insulation on it which held by 5 small (very small!!) screws at the bottom of your Imac. After you done it - it's easy to pull everything! Pay attention to the fact that one of this 5 screws at the center are more shortly than others.

    dv1977 - Replica

    After doing the replacement the adhesive still sticks quite good enough to hold the screen in place. Maybe this isn't rock-solid, but enough for me.

    If you're changing cracked EMC 2638 display to new assembly, there's two more steps:

    Step 24: Use the tip of a spudger to flip up the metal retaining bracket on the display data cable.

    Carefully pull the display data cable from its socket on the display assembly.

    Step 25: Use the tip of a spudger to unplug bracket of the thermal sensor small cable near display data cable.

    Carefully remove scotch tape covering thermal sensor. Using iSesamo or flat tip of the spudger carefully peel the thermal sensor away.

    The key thing is to never put any force on the opening tool when working through the tape. Just roll it back and forth with ease.

    • Terminare l'applicazione dell'attrezzo per l'apertura nella parte inferiore del lato destro del display.

    • A questo punto, si consiglia di ripassare nuovamente l'attrezzo lungo tutto il display, per fare in modo di tagliare il più possibile l'adesivo.

    Yes, do it many times to loosen the adhesive.

    Noah Ralston - Replica

    Would be good data to show the 3 areas (wifi antennas where the "tape" is larger and covers them. The rest of the "tape" is 1.4" and easy. Also after removing the display, be sure to remove the old "tape" from both the display and the rubber parts of the case. Use the spudger to start an end and it should pull off easily. Careful on the baackside of the display as you can scratch off the black paint/covering.

    • Sebbene l'attrezzo per l'apertura tagli la maggior parte dell'adesivo, il display sarà ancora leggermente attaccato al case. Occorre una scheda di plastica per liberare la parte restante dell'adesivo.

    • Poggiare l'iMac su un tavolo, rivolto verso l'alto.

    • A partire dall'angolo superiore destro dell'iMac, inserire una scheda di plastica fra il display e il telaio.

    • Fare attenzione a non inserire la scheda di plastica per più di 0,95 cm, in caso contrario si rischia di danneggiare i componenti interni.

    this step is extremely important NOT to stick in the cards too far….. doing so, you risk a 600 euro replacement as I experienced………

    • Ruotare delicatamente la scheda di plastica lateralmente per creare uno spazio fra il display e il telaio.

    • Eseguire movimenti lenti, facendo attenzione a non fare troppa pressione sul vetro del display, poiché occorre solo uno spazio di circa 0,63 cm.

    This part must be done very carefully or you can damage the flat cable from display, despite it was under a iron cover.

    • Far scorrere la scheda verso il centro del display per tagliare il resto dell'adesivo lungo l'angolo destro dell'iMac.

    • Occorre fermarsi prima della fotocamera iSight per non danneggiarla.

    You don't need to do it like this, simply open the iMac bendidng the LCD completely and use the pizza cutter to remove the adhesive.

    Felix - Replica

    Agreed. The card is too thick to cut through the adhesive in this way. Use the pizza cutter or a sharper blade at this point.

    • Mantenendo entrambe le schede di plastica inserite vicino agli angoli come indicato, ruotarle delicatamente sui lati per aumentare lo spazio fra il display e il case.

    • In presenza di sezioni ancora incollate che non si separano, fermare la rotazione e utilizzare una delle schede per tagliare l'adesivo restante.

    • Iniziare a sollevare la parte superiore del display dal telaio.

    • Sollevare il display di pochi centimetri, poiché i cavi di alimentazione e dei dati sono ancora collegati alla scheda logica.

    • Solleva lo schermo abbastanza in alto da avere un accesso facile al connettore, ma non tanto da strappare i cavi e forzare i rispettivi connettori (alzalo di circa 20 cm).

    • Mantieni lo schermo con uno mano mentre con l'altra stacchi il cavo di alimentazione dello schermo .

    Can this cable be replaced? I am worried mine is damaged. I have no display after the screen fell and stressed the display flex cables following an SSD upgrade.

    Jeremy Brainard - Replica

    This step should be done with extreme caution and care, as this step 19 is not described in great detail (sorry, author).

    The first (most outward) cable will slide out by gently pulling it by its tabs. The second (inner) cable is more tricky, as the locking lever must be moved backward first, before gently pulling backward on the cable connector. The angled tweezers are useful here, to help lift that locking lever, because fingers are too big for this.

    Ernst - Replica

    be VERY careful and SLOW...take your time. These displays crack VERY easily when removing and they'll spider web on you. I've done probably 20 or so of these and cracked 3 being super careful.....ugh.

    • Solleva il display in posizione quasi verticale.

    • A questo punto ci sarà sempre una striscia di adesivo nella parte inferiore del display che lo terrà incollato alla scocca come una cerniera. Puoi allentare questo adesivo muovendo il display su e giù per alcune volte.

    The best way to remove the chin adhesive is to use the tabs at either end (there are two strips that run from each outside corner to near the centre). Carefully pull the tabs up and the strips should peel off.

    • Quando installi un nuovo disco, e' utile utilizzare un nastro biadesivo per attaccare le protezione al tuo nuovo disco.

    reconnecting the new drive can be a little tricky as the sata connector in the Mac is hard to align. I found that it helps to move the end of the bumpers out of the way, then push them back into position once the drive is connected.

    Can I install a Samsung 850 EVO 500GB to replace my 1TB 5400rpm disk? and is a seperate thermal sensor/cable needed to prohibit the fan to run at 100% all the time?

    Maurits K - Replica

    Yes you can install ANY SATA SSD.

    And no … there is no thermal sensor on the drive. You don’t need them on these models.

    Can I install a Seagate FireCuda 2TB to replace my 1TB 5400rpm disk? and is a seperate thermal sensor/cable needed to prohibit the fan to run at 100% all the time?

    andrew mudd - Replica

    Did you ever find out if you could replace your 500 GB with that Firecuda? I’m looking at doing that. I need more storage for my 500 GB photos library and don’t want to pay so a ton for the SSD that is big enough.

    where is the guide for the follow up ?

    installing a new hard disk and closing the screen back up.

    yog1389 - Replica

    The SSD was a HUGE performance boost over the 5400rpm drive my iMac came with. If you’re pulling your hair out because Lightroom has become excruciatingly slow, upgrade your hard drive to SSD. You will not be disappointed.

    The kit has everything you need. Follow these instructions carefully and you’ll be fine.

    Mike Mullis - Replica

    Huge improvement! It’s like a new machine. Highly recommended upgrade.

    Take care with the adhesive strips, and don’t forget to set new SSD as the boot disk (System Preferences, Startup Disk) after you’ve tested its bootable.

    Stephen Babbage - Replica

    I previously had a fusion drive and installed a SSD. Will there be any issues with the ssd portion of the fusion drive? I still see it there in disc utility. Also, I’m showing two SSDs, along with the 32 gig one. Is that correct or did I create something that shouldn’t be there?

    rossmueller - Replica

    I have this same question. I’m showing 2 drives but 1 is grayed out on the computer screen when I click on it nothing happens.

    Frank -

    A fusion drive combines two physical disks via software to act as one. It it something that has to be done manually and expressly. When you first got the computer, your fusion drive combined disks A (SSD) and B (HDD). If you replaced B, then you probably have an unused 32 GB blade SSD along with your new SSD. It possible to create another Fusion drive, but you’d have to start from zero, because creating a fusion drive erases the individual disks completely.

    also, not 100%, but I tried for several hours the other day and I’ve come to the conclusion that my version of Big Sur (11.1) doesn’t support Fusion Drives. Correct me if I’m wrong. Or maybe it’s because I’m running Big Sur on an unsupported iMac.

    It is also possible install the bumpers after getting the drive cable attached. This gives you more room to work with the cable and drive.

    Sean Kane - Replica

    The hardest part was to plug the connector into the new SSD. I loose the two screws of the adjacent (left) speaker and move it just enough to have sufficient space to introduce my fingers to push the conector into the SSD. Left the replace of the rubber bumpers after reconnect the SSD, is easy to handle without it.

    Dennis Salas - Replica

    I bought Samsung QVO 1TB SSD and now the fan is blasting fast and loud. So if these don’t use the thermal cables then what seems to be triggering the high temp? Obviously it’s the hard drive but could it be that the drive was cloned? I’m kinda stumped, I know I can control with software but some of you are saying it should run normal after install. Thanks for the info.

    Is there a PCIe slot for an SSD instead of the SATA 3.0 2.5”?

    thank you,

    deejaysurfer - Replica

    The step-by-step guide was awesome and easy to follow. As others have commented, getting the SATA connector onto the SSD is tricky but not impossible. Just pull back the rubber bumpers long enough to reach the connector, then flip them back into place before seating the drive. One comment for my machine (late 2015 21.5”): There is no mic hole for my model, so while I was a little confused at the instructions on reinstalling the adhesive, the drive replacement went like a dream. And I saved myself the $120 labor the local Mac shop wanted to charge me.

    Glenn Pettit - Replica

    Hat alles prima funktioniert. Leider läuft der Lüfter jetzt auf 100% und kernel_task Prozess ist bei über 300%. Was habe ich falsch gemacht. Diagnose meldet jetzt einen SMC Fehler und CPU-Proximity liefert keinen Wert.

    Kann jemand helfen?

    Michael Schmitz - Replica

    This is the least accurately described step (sorry, author). While removal is easy, inserting the new drive in its place is a bit tricky. The key here, is to insert the new drive with its rubber bumpers back in its space, so that it is fully seated down in its place *before* the connector can be re-attached. Once it is seated in place, use the flat end of the spudger to gently manoeuver the connector back into place until it is firmly connected to the drive.

    Ernst - Replica

    Reassembling the iMac is not simply following these instructions in reverse order (sorry, author).

    Before embarking on the home stretch, it is very important to carefully study the guide about the Adhesive Strips Replacement (iMac Intel 21.5" Retina 4K Display (2017) Adhesive Strips Replacement - iFixit Repair Guide), as this a tedious and time consuming process. Perfect alignment of those adhesive strips takes some concentration, because you will want to have your display panel back nice and tight and fully aligned with the case. Once all strips are in place, the 2 display connectors need to be gently reattached to the motherboard, before closing up the panel. I took my sweet time for that step, and thankfully have a perfectly aligned display panel back in place looking no different from the factory fit.

    I got a 4 TB Seagate Barracuda HDD as a replacement for a client. (Going for capacity over speed.) Does anyone know if it will fit? It’s definitely fatter than the other HDD/SSDs I’ve installed before.

    David - Replica

    There needs to be more added to cover the first part of re-assembly. To connect up my SSD, I needed to remove screws that held in place the black plastic to the left of the drive bay. This was only way to get the added space needed to connect the SSD to the drive cable. I also connected the SSD first, then attached the rubber bumpers, simply to give me more room to maneuver the drive next to the connector. All in all, yes, a person well familiar with tearing down iMacs could do it in an hour or so. But frankly, the design of this iMac is a total horror show when it comes to repair or replacement of parts, especially given its reliance on glue and adhesives. Gee, just like other Apple products.

    Ben Myers - Replica

    Ben, after you replaced the HDD with SSD, did you have any fan issues on the A1418 model iMac? Thinking of doing this but I’ve been reading for hours and seeing mixed reports about thermal sensors.

    Christopher Henley -

    This iFixit tool (iFixit Opening Tool) will be your best friend when it's time to install your new 2.5" hard drive. Simply hook the tool to the back top corner of the iMac SATA adapter, connect your hard drive loosely to the SATA ports and use the tool to pull the SATA adapter forward into the hard drive.

    iannai29 - Replica

    After replacing the hard drive. All went well BUT -now my mic does not work. It's the single hole on the bottom. Any ideas anybody?

    Paolo Alberto - Replica

    Please update the end of this guide, pointing the customer to the guide for replacing the display adhesive strips. You provide a single kit for this procedure, and the customer has to figure out that they must follow two independent guides, in order to successfully complete the installation.

What type of SATA SSDs are compatible with iMac? I don't want to buy the kit because I have the necessary tools, but I'd like to know which brand of SSDs work the best.

Avery C. - Replica

>Will take any SATA SSD.

>On a mac with a fusion drive, it just removes the spinning drive from the mix, leaving you with a separate 28gig or 128 gig SSD drive that will appear on your desktop along with the newly installed SATA SSD.

>NO TEMPERATURE monitor is needed. This generation of iMacs has done away with the propietary temp sensor. It just relies on S.M.A.R.T. tech now.

robert Seith -

Does the screen stick back on with the same adhesive or do you have to reapply new adhesive? If yes, does it come in the kit?

Rick Hahn - Replica

You have to apply new adhesive. Go slow and careful, it’s really not hard at all.

robert Seith -

Will this work similarly for an iMac with a fusion drive? -> (what about upgrading the ssd portion?) Will there be a guide for that in the future?

Lucas - Replica

The 1TB fusion drive is simply a 1tb standard SATA spinning drive combined with a separate 28gig blade SSD. The blade SSD is much harder to get to, but when you replace the 1tb SATA drive with an SSD, you then have access to both drives, the 28gig blade SSD appears on your desktop to use and format as you wish, and you then have the newly installed SSD to use and format as you wish.

robert Seith -

Is the temperature probe/OWC cable nescessary for the Imac to register temps from a 3rd party SSD? I'm thinking about changing the 1TB hdd for a Samsung EVO SSD

Maurits K - Replica

No temp sensor is used on these 2017 models. Put in the new drive and you’re good to go.

robert Seith -

I'm planning to remove the Fusion Drive from the iMac 4K and replace it with SSD blade!

Is that possible?

How much does it cost?

thanks:)

Is there any posibility to replace the normal 1tb HDD by a NVMe SSD like the FusionDrive Model has?

Kevin Braun - Replica

If the iMac is originally SSD-only, can this procedure be used to add a SATA second drive?

Can I replace the 1TB HDD to 2TB HDD? Will it still work as Fusion Drive?

And do you need a iMac specific model HDD or whatever brand of HDD?

Way White - Replica

As far as I know, the fusion drive models actually have a HDD and a separate nvme SSD. 2tb upgrade will work.

I have a 2017 iMac 21.5” with Retina, Serial Number C02WN5FQJ1G5

I upgraded to an SSD and increased the ram. I cracked the screen glass during the reinstall. I have searched and can only find a complete display for around $300. The display is working fine. I only need the glass. Can you advise if any of the older model’s screen glass would fit.?

Ich habe bereits die neue SSD eingebaut ohne die vorher mit der alte zu Klonen. Besteht jetzt eine möglichkeit im bereits eingebautem Zustand die zu Klonen?

laios vangelis - Replica

Amazing difference. Thanks for the guide—everything worked great. After cloning my old hard drive, putting it all together was a piece of cake. I took my time and didn’t rush, and everything came apart and went back together just as the guide said. Couldn’t be happier. I feel like I’ve got a brand new machine. Wouldn’t have felt comfortable without following something like this. Thanks!

David - Replica

Wow, what an improvement in performance! It’s like a totally different computer. I should have done this ages ago. Actually, they never should have sold the device with the original slow hard drive.

This is about as easy as it gets with iMac upgrades. The hardest part is scraping off the old adhesive. Also, be sure not to cover up the microphone when you add the new adhesive strips!

Stephen - Replica

I am trying to replace the 1TB HDD on a Retina 4K Display (2017 iMac 21.5" with a Crucial 1TB SSD.

— Booted into Recovery Mode to use Terminal commands to split the two drives into a 28GB blade SSD and a 1TB HDD

— Opened up the iMac and replaced the HDD with the 2.5" SSD

— Booted the iMac from a macOS 12.5 installer drive and tried to format the SSD using Disk Utility. But whether I formatted it as HFS+ or APFS, it would fail validation (via First Aid)

— To test if it was a bad SSD, I connected the SSD to another Mac running macOS 12.5 and reformatted the drive successfully as either HFS+ or APFS. I then installed macOS 12.5 on the SSD and booted the Mac from the SSD. I also booted the iMac from the SSD in an external enclosure. So I know I have a good SSD that WILL boot this iMac

— However, when I connected the SSD to the iMac’s internal 2.5” bay it would not “see” the above SSD and obviously would not boot — However, it DOES “see” the original 1TB  HDD

Why is this iMac have a problem with this SSD?

eogold - Replica

To be clear, this iMac came with a 1TB Fusion Drive.

eogold - Replica

My iMac did not come with a 2nd drive from the factory. Would I be able to add one?
