How to Upgrade/Install Memory in a 21.5-inch iMac (Mid 2017) iMac18,1 iMac18,2

[@alessandrochiarenza]

Holy cow, 75 minutes for changing the RAM modules is not an upgrade...it's a surgery!!! However, very professional video. Thanks!

[@midisqusdisqus802]

Same thought here. You almost have to disassemble the entire iMac! Holy God! I'm not afraid to do this type of surgery (I already had a very complicated one many years ago when changing the internal battery of a Titanium), but... just to UPGRADE Apple's RAM? In the past Mac's were designed with simplicity in mind. Now all is the opposite. Why? We miss Steve Jobs.

[@darkbrich]

Dude, 4 hours

[@theKellyG]

Buying the ram extra from apple is extortion, so take your pick. At least this way, you learn something useful.

[@fredmoody1914]

I have upgraded the RAM many times on three previous iMacs I owned. I remember when upgrading was as simple as removing a small panel from the bottom (or back) and replacing the memory modules. Maybe took 5 minutes. My mid-2011 iMac was a piece of cake. I even upgraded to a SSD and it was not difficult. The instructional videos by OWC are excellent. So now I have my 2017, iMac 18.1 and I don't think Apple could make it more complex to do. I contacted my Apple dealer and they don't even to memory upgrades. It's not worth their time. It would appear that Apple is making it more and more difficult for users to do any upgrades to their computers. I've been a loyal Apple fan since the Apple IIe days and have owned about 12 different computers but their pursuit of making their computers as thin as possible and impossible to service is a joke. I have no problem doing this and enjoy the challenge but some of Apple's design decisions are asinine. I'm a photographer and the new iMacs don't even have an SD slot! It was bad enough when they moved it from the side to the back.

[@bortsampson3642]

Same here, cannot believe how hard they make it to remove this thing.. and to top it off my kid's got a bad case of diaper rash!

[@midisqusdisqus802]

And your Apple dealer is right. Consuming so much time just to... upgrade iMac memory! 75 minutes of surgery to only... change a module! Holy God! Aaarghhh! We miss you Steve (Jobs)!

[@romadixx]

Fully agree with you!

[@hiker64]

I think the 2019 is even more convoluted - I'm going to upgrade my 2017 first, then Ram and HDD on my 2019. not looking forward to either, to be honest. Yeah, the 2012-ish just required taking off the access plate on the bottom for the memory - Like 5 minutes to upgrade. This hot mess is another story.

[@leoc75]

@@midisqusdisqus802 Miss Jobs, too. Now the Apple M-series CPU makes it even harder for software engineers to use VMWare for work so many developers in my company switched to Windows PC because of that. Apple MacBook are left to people (like sales, marketing, PMs) who don't need to run development tools. Pity... Mac mini and early iMac are the best time I have with Apple Mac products.

[@williamsilcott2519]

Completed the upgrade in a couple of hours with no issues at all. If I do this to another iMac I think I will be able to complete in an hour easily. I also replaced the HD with a 1 TB SSD and replaced CMOS battery while I had it open. If you have an older iMac I highly recommend doing all this. For around $200 USD I now have a mac that can keep up with my newer macbook pro easily, minus the processing power you get from M1. Unless you really need to do heavy lifting for CAD or gfx work, the processor isn't going to be a deal breaker. So happy I did this.

[@peterkiss501]

I havent done it by myself but want to give a bit of push for thise who are just thinking of doing this: Owning a 27 inch 5k top model I couldnt believe the used 21.5 ac is not faulty being so slow. Then got this change done by a friend, put SSD and 2x 16gb ram in and the 21.5 imac is booting quicker than the high end 27 inch, cuts video and does everything at least the same speed. Amazing! Thanks

[@retrorter89]

Thank you for taking the time to make this video, it has persuaded me not to bother trying to upgrade my iMac. How hard would it have been to have an access panel at the rear (Obv they dont wan't you upgrading it at all, maybe I could make one with my dremel lol !?!). As memory upgrades go, this is by far the most insane I have ever seen. So many possibilities for a bad ending, from a cracked screen to getting electrocuted. Only thing I think I could add is If I ever did get that far I would change the CMOS battery while I was in there.

[@naughtytoaster3611]

Finally finished, took us about a hour and a half. Great video guys massively appreciated 👍🏻

[@wallrrusslord4779]

Great guide! Went from 4gb ram to 32gb. Only problem I had was the one power cable under the logic board you had to squeeze to pull out. After twenty minutes it finally did lol don’t squeeze from the back of the tab, squeeze at the short front bit.

This is a great instructional video to prepare yourself and to follow along during the upgrade. Some of the cables and connections can be tighter than what it seems here. Just take your time and be careful.

[@GarciaVideoProductions]

Did you do it successfully?

[@hiker64]

Pro tip: If you're going through this process to upgrade your memory, also replace that old SATA drive with an SSD at the same time since you have everything ripped open already.

[@GreyMatterTechnicalServices]

If you just upgrade the RAM it's hardly going to matter. The SSD is a must!

[@AdamStansbery]

I would find out exactly where the ram is located from the back of it. I mean map it out exactly. Draw a square/rectangle on the back a little larger than exactly where the ram is located. Search for the best way to make the to be new ram access door detachable and remountable. Probably rubber seal or 3d printing. Drill one hole at each corner of the drawn on rectangle/square. Possibly in a some other spots as well. Find a way to run a dremel with the smallest bit possible attached to a sweeper hose and attached to something that will guide it along a straight line. Aslo only deep enough to go through the back panel. Then cut out the rest of rectangle. Stopping half way to tape what has been cut to the rest of the back. Take some measurements for the gap cover. Upgrade the ram. Testing the new ram. Confirm, create, and test the new door latch mechanism. Find the best way to monetize the whole procedure for the most ease of the buyer.

Sounds like a really fun project, if you happen to have an extra iMac laying around for parts 🙂🔧

There could be some possible incompatibility issues, this is why we recommend using the memory here: eshop.macsales.com/shop/memory/imac-2017-21.5-inch, as this is both compatible and will work best inside that machine.

[@AptisTutor]

Thanks a lot, it is an excellent tutorial @OWC. A couple of the screws on the speaker were extremely tight and I had to use a tiny drop of oil to loosen them and come back to it later on so it took a lot longer. As you've mentioned in this post, a good idea is to use tape and reboot to make sure that it works - and then when everything works ok, use the proper sealing tape. (My microphone doesn't work now - which isn't a problem as I always use an external one anyway) but I successfully upgraded to 64 GB RAM.😅😅

[@poweredbyowc]

Hello Shon Yagutilov, For your iMac you can change out the memory to the max of 64GB, we have provided you the memory upgrade link below. eshop.macsales.com/shop/memory/imac-2017-21.5-inch Now for the SSD it would depend on how you purchased the iMac. If you purchased it with a HDD yes you should have no issues with installing that Samsung drive but now if you purchased the iMac custom with a NVMe SSD you will not be able to install that Samsung drive due to the iMac not having a SATA connector in the mac 21.5-inch iMac models that came with a factory-installed SSD or Fusion drive.

[@poweredbyowc]

Hi @Sandeep! Have you reached out to the RAM manufacturer already for help? If you purchased the RAM directly from OWC: eshop.macsales.com/Service/ Since the iMac18,2 is spec'd out by Apple for 2 x 16 GB, and we've discovered in the years since that it will accept 2 x 32 GB RAM, I suspect there may be something else in your particular situation that may be causing the behavior.

[@ernesthemingwayrocks9732]

What pisses me off is that they could have very easily engineered a removable port in the case over the memory modules as they are flush with the back of the case anyway. They’re purposefully making it difficult

[@midisqusdisqus802]

Yes... making it difficult on purpose. Because if you analyze the video, you end up with the RAM modules facing the back of the case. In a 27-inch model they simplified the procedure, but in the 21.5-inch model... they push you to "think twice" if you investigate beforehand how to expand your RAM memory. Too bad Apple!

[@doffydonquixte]

Is it a reason you didn’t replace the ram from the back of the imac where you push the button and there is a slot that comes off instead of taking screen off the long way? Not being smart just asking from others I seen, or is the 27 inch and 21 inch ram replacers different?

[@poweredbyowc]

Hey Doffy, That is a great question, and many have wondered the same. Unfortunately, since 2012, Apple decided to design the 21.5" iMacs without a back door for RAM upgrades. This means the only way to upgrade the RAM in the 2012 and later 21.5" iMacs is through a more involved process that requires opening the machine.

[@N8andKids]

Question , should I go back in to my Mac and replace the unknown brand card with my spare Crucial card to pair with the other Crucial card? BTW the Mac seems to be working ok :-/

[@poweredbyowc]

Apple uses a variety of different manufacturers to outsource different components. My recommendation is that if they are working well, to leave them...or if not...consider an upgrade and upgrading the RAM to a bigger and faster kit.

When they got to the part of the video where they finally pull the logic board I couldn’t help staring at the wide open section of metal that is the actual back of the iMac. You know, the spot where Apple could have easily put an access panel. They have become the polar opposite of the company they once were. Great video from OWC, but there’s just way too many points where a connector is not going to come loose, or a screw will get stripped, etc. for me to justify attempting this.

Alright, so I did it. Couple things to add. My computer did not have a hard drive like it shows in the video so it was super easy. The video makes these connectors look big. They are not! Also, I did the whole thing while still having the power supply still attached. I could not for the life of me get the last plug detached. I for sure thought the computer would not work because the power supply banged a bit, here and there. The whole process took about 4 hours, but now I have 32gb instead of 8gb.

At 11:33 it's really difficult to not trap that tiny ribbon cable that I believe might be the microphone. I had to fish it out of of the bottom of the aluminum case, gently pull it up and tape it to the front of the case so the logic board didn't trap it again as the board brushed by the cable while being reinstalled. And if you're like me, you can swear at the top of your lungs at Jony Ives for burying the memory DIMMs so deeply in this iMac - literally cruel and vicious behavior, anti-consumerism at its peak.

[@poweredbyowc]

Thanks for sharing your experience! That tiny ribbon cable can indeed be tricky to manage during reinstallation, and your solution of taping it to the front of the case is a great tip for avoiding frustration. And yes, Apple's design choices-especially when it comes to burying components like the memory DIMMs-can feel pretty user-unfriendly at times! We hear you. Hopefully, the upgrade process went smoothly in the end, despite the challenges. 💙

To incentivize you to either purchase the higher end model or two furnish the cheaper model with obscenely overpriced memory.

[@pillettadoinswartsh4974]

I'm old enough to remember when iMacs had a little door on their bottom, which allowed you to *E-A-S-I-L-Y* upgrade the RAM. Took all of two minutes. One screwdriver. Apple has gone to hell.

[@tobysimmons6185]

Not worth doing buy a newer one or refurbished that already has the memory you need. At least iMacs hold there value for reselling.

[@jimmysgarage9068]

Dang. I just went from a 2009 iMac that I put an SSD and upgraded RAM into, to a 2017 Retina. Looks like surgery to upgrade the RAM... Thanks Apple.

[@poweredbyowc]

That is awesome to hear Jimmy's Garage, we are glad to hear that the upgrades brought your Mac back to life.

I just tried updating mine, and it won't turn on. Frustrated.

[@RX93akhrouk]

I own 2009 and 2017 .it was easy on 2009.I was wondering how to upgrade on 2017 , but It is a quite,,,,,long process isn it..XD

[@poweredbyowc]

Thank you for the comment. It is a lengthy process, but it’s totally doable and worth it, in the long run. I find that working at your own pace and pausing the DIY install video from time to time really helps.

[@photoboyjet]

I've been building PCs for over 20 years. It is beyond ridiculous to go through this many steps to install RAM - about the most basic of upgrades. Most desktops and laptops are easier than this. Unless the idea is to keep folks from upgrading in the first place.

[@ember5935]

As a 16y/o this is too much work lol all I could get to is the harddrive and upgrade it

[@redtails]

man wth why isn't there just a door on the back of the machine.

[@poweredbyowc]

Hey Redtails, unfortunately the 21.5" models being physically smaller than the 27" doesn't allow for easy access since they have to move where the RAM is. Why they couldn't have put a door where they moved it? I'm not sure, but for the 21.5" models it's unfortunately a big hassle to upgrade.

[@shadow.banned]

What is Apple's problem?

[@JoeDplummer_]

I like Macs but Apple did a very unfriendly service design. OMG!.. What a nightmare to upgrade your Mac. SHAME ON APPLE 😕👎

[@AudiSportFan1970]

I upgraded the RAM in my late 2017 21.5” iMac by removing the screen, the cooling fan, and the camera cable, carefully tilting it in its side and replacing the RAM. You don’t have to go through all of this LOL!!! Ridiculous!!!

[@poweredbyowc]

That is nice to hear that you were able to find another way to do the install of the memory that worked for you.

[@midisqusdisqus802]

You're right. I found the video that shows you how to do it. Even if it's a little bit tricky, you can avoid the hassle of almost completely disassembling your iMac. You'll need only FIVE MINUTES to upgrade your iMac's RAM (after the screen remove step, of course). It's up to you.

[@robertmiller2929]

The short answer is it’s a pain in the butt. Although if you are mechanically inclined and have patience like a Venus Fly Trap it’s doable. Wait? Do they have patience? OWC continues to be a great company and I hope they can diversify as Apple moves away from a company who thinks about the user. I’ve been a diehard Apple fan for 30 years but each year I loose a little more faith. Apple is solely focused on profit and their customers are no longer the main focus. The passing of their founder? Maybe but I think it goes deeper than that. A billion dollar company manufacturing in China? God Bless… not America. P.S. I was able to upgrade my daughter’s computer put it back together and when I turned it back on… it didn’t start smoking. Thank you OWC, you obviously still have a soul.

[@poweredbyowc]

We are glad to hear that the upgrade to your daughter's computer was successful.

[@poweredbyowc]

Sorry to hear it was unclear, what part had you struggled with? We might be able to clarify, I'd probably recommend giving us a call if possible at 1-800-275-4576 and speaking with a technician.

[@alecgoudreau6397]

Take it all apart put it all back together and then find out one or both new sticks is defective?! a door in the back like the 27 inch makes this delicate surgery unnecessary.

[@poweredbyowc]

We completely agree, but regrettably, Apple has chosen to make the installation process a bit challenging for both consumers and third-party upgrade companies like us.

[@jpcooler]

This just proves Apple is looking out for Apple and not the consumer, sad

[@midisqusdisqus802]

Unfortunately, that's correct since Steve Jobs is no longer at Apple.

[@shadow.banned]

Doesn't seem like 32-64GB would really be necessary.

[@poweredbyowc]

We do not recommend that you go 32-64GB if you are not a professional. We only recommend if you are using large RAM requiring Applications and softwares such as photoshop, illustrator and Adobe.

[@youknownuno]

Dude you could have written a disclaimer that some boards don't even have the ram slots, I got to part 2 only to find out I don't have those slots! Same model, iMac 21 inch 4k 2017. Can't believe I went through the trouble, and now I have to piece it back together and hope it still works

[@poweredbyowc]

We would recommend double-checking your Model number as some years did not include the ability to upgrade RAM. The information we are looking for to confirm your model is the model identifier that is found in your system information.

[@muenstercheese1653]

Bruh i bought 32 gigs of ram and was going to put it in, then I saw this video and I'm just gonna send It back. This also voids the warranty as well so yea.

Aren't most of these out of warranty by now anyway?

Elsa, I'm sorry it took you longer to do the iMac memory upgrade than is shown in the video. Our technicians routinely upgrade memory on all sorts of Macs, so of course they can work more quickly than someone who may not have done a memory upgrade before. On the newer iMacs like the 2017 21.5" OWC does recommend professional installation.
