Introduction

Ce guide vous aide à remplacer/mettre à niveau le disque dur.

Collez une ventouse dans chacun des deux angles supérieurs de la vitre. Pour fixer une ventouse, commencez par la positionner avec la poignée mobile parallèle à la surface de la vitre (comme illustré dans les première et deuxième photographies). Tout en maintenant légèrement la ventouse contre la vitre, soulevez la poignée mobile jusqu'à ce qu'elle soit parallèle à l'autre poignée (comme illustré dans la troisième photographie).

  • Si la ventouse n'adhère pas à la vitre, essayez de les nettoyer, l'une et l'autre, à l'aide d'un solvant doux.

  • N'utilisez pas les ventouses pour porter l'écran. Si l'une d'entre elles se détache, l'écran risque de tomber.

  • L'emballage d'origine de votre iMac est un endroit sûr pour conserver votre écran. Sinon, vous pouvez aussi étaler une serviette sur une table et poser l'écran dessus.

You can easily lift the glass panel off the magnets with only your fingernails (or something thin like a credit card or a guitar pick). No need to buy suction cups you will only use once.

Nick Caron - Réponse

Yes, you don't need the specific suction cups to remove the display cover - it's held on by magnets, and if you start at the center by the iSight you can work out to the edges and remove it. I had an iPhone screen suction cup around and it helped with balancing the screen when you pull it out fully, but by no ways is it required.

jtowner - Réponse

Great guide and pretty straight forward the only thing that took me ages and I didn't manage to undo were the power btn cable (step 28) and the thermal sensor (step 25) Seemed like they were glued on! Very difficult to remove and obviously conscious so I didn't break anything!

Eddie - Réponse

Thanks!!! Worked excellently.

I used a plunger (clean first ;-) to get the screen off, and http://exirion.net/ssdfanctrl/ for fan control.

Then, i did not take out the whole display and left it in the hinges on the bottom side and held it up with two small cardboard boxes. Easy enough to disconnect the hdd then.

I replaced with an ssd, put that into a ssd enclosure. Had to drill an extra hole in it to fasten the pins that hold it in place.

Used Carbon Copy Cloner to make an image from the old hdd, with the sad connected via usb. Checked it of it booted via System Preferences > Startup Disk. It worked so the took the imac apart and replaced the disk. Booted, everything was working as always, only faster!

Frank303 - Réponse

I'm replacing my optical drive too. what exactly needs to be plugged into the SSD? I don't have the kit - as I am not sure one is required if I buy something like this: http://www.amazon.com/gp/product/B0056OB...

Can you please advise? Can I do it with this piece, or do I need to get the entire bracket kit?

Allen Borza -

My display data cable forks, with a smaller section going up near the camera board. Where it forks, it is attached to the aluminum plate that attaches around the cpu board. I haven't seen any images that look similar, and I'm stumped at how to remove this second section of the cable. 2010 i7 build to order

Awolf - Réponse

Agree with the other comments here. Despite buying suction cups, not sure they were necessary as the screen removed very easily. A sat nav suction cup would do the job fine.

Stuart Bloomfield - Réponse

I can confirm that it is possible to remove the front glass using fingernails rather than suction cups. It isn’t easy, but if you try you should be able to pry off the glass.

I did this twice: once at the beginning of the procedure and once again at the end, when I realized that a big pice of lint was trapped under the glass.

Soulevez doucement la vitre perpendiculairement à l'écran LCD pour dégager les broches de montage en acier fixées en dessous de la vitre, le long du bord supérieur. Retirez la vitre en l'éloignant du bord inférieur de l'iMac et mettez-la de côté. N'utilisez pas les ventouses pour transporter le panneau en verre - Si l'une ou l'autre des ventouses venait à se détacher, le panneau pourrait tomber et se briser.

you should do this mac up, because, for me, one of the suction cup failed, and the glass fall into the lcd screen. Now there is a big hole in it...

Alpha Dimension -

Reassembly: After powering on and running for a few minutes, found a large whitish patch on the screen. Persists after powerdown.

Turned out to be condensation, though it didn't look like it - more like fine white powder rubbed in. Humidity is very high this time of the year. Fix: start airconditioner in a room, leave it running a while, take iMac in, prise open the glass again. Condensation vanishes instantly. Keep it out for a ~15 minutes running infinite loops to get iMac nicely heated up and fans running. Snap glass back.

ganesh - Réponse

I used a Swiffer dry cloth to get all the dust off the screen while just blowing with my mouth at a steep angle. I know I didn't get every speck, but the screen looks perfect once assembled and lit again. Removing the glass from the screen is pretty easy if you need to re-clean it.

Jay Gillibrand - Réponse

I used a microfiber cloth instead, which worked well. The same type as yo use to clean eye glasses, but in a larger form factor.

Daniel -

The Swiffer idea worked great! I just brush it over the LCD and glass panel lightly, and all dust particles are gone quickly. The screen after boot up looked beautiful. Thanks!

dtsai2 -

I strongly recomment to detach the suction cups while working at the rest of the steps. In my case after half an our i heart a crack noise behind me on the table... The vacuum of one of the suction cups braked the glass! maybe there should be a warning in the Repair guide

shippe - Réponse

I didn't crack the screen, but it popped out of the shims and then popped back in, as if the glass edge is magnetic or has steel in it to connect to magnets. Be careful with this step — it is pretty nerve-wracking, but doable!

Alex Reynolds - Réponse

You need a big clean surface free, or at least 2 or more free surfaces because the iMac, the glass and the LCD display are quite bulky. You'll also probably need space for a tablet or a laptop to read this guide while you are working. And don't forget room to work on the optical unit and for the tools you are going to use. I covered a large table with a double layer of bubble wrap. In my opinion it's better to put the glass face down to limit powder sticking on the internal surface.

Roberto Blandino - Réponse

Thanks good advice! I was wondering exactly about the working space issue!

I followed the procedure in the Apple Technician Guide and it was a lot easier. Stand the iMac upright on the stand (as per normal operation) and then carefully tilt the top of the unit towards you while holding the top of the LCD. The LCD just falls forward into you hands. It is also then easier to disconnect the cables.

iandh - Réponse

This procedure can be VERY dangerous. Why? Because there is the possibility of a gravity disaster if you lose control of the screen and it falls before you disconnect the interface cables. I know. It happened to me. After studying the Apple directions I came to the conclusion that I would need both hands on releasing a couple go the cables and decided to tape off the screen in the open position - which I did very carefully and securely. What I did not account for was the tape not adhering. Needless to say when it came loose the screen fell and ruined the connector sockets (and my computer). This could also happen just trying to hold the screen with one hand while spudging the connectors apart with the other as well. SO. LAY THE iMAC DOWN! DO **N O T** GIVE GRAVITY THE CHANCE TO RUIN YOUR DAY like it did mine!

After disconnecting the VSync cable, I was able to keep the screen wedged apart by 8" which gave me enough working room to extract and replaced the hard drive without having to remove Step 6 - 8. This resulted in a faster change out of the hard drive.

Amen brother! These are great guides, but could be improved with tips to simplify some processes. I just did the same as you, and it was quick and easy, with less chance to damage cable connections.

Once I put the tip of a very small flat-head screwdriver on the other side of the spudger tip, the connector popped out.

I've managed to break off the fitting in step 6 trying to remove the screen, would anyone know the part to buy or how to fix this?

jonostainsby - Réponse

It is very hard to detach the connector with the spudger. I tried forcing the connector out with the spudger by pushing on one side and then the other repeatedly. After several times it finally came out. A tool would be useful for this; there must be special plyers for doing this. Fingernails on either side seems most obvious, but maybe there is a downside to this ?

Daniel - Réponse

Rocking it back and forth with some “outward” pressure on both sides was the key. This was the only connector in this upgrade that gave me a problem.

Do step 7 first. The cable is much shorter and more fragile, you'll have more space to remove the other cables if that one is removed first. On my mac, the cable in step 7 was glued down and had to be freed up before I could pull the connecter out of its socket.

Good idea! I used two chopsticks as they are longer. Placed them near the corner and use one of the T10 screw's hole in the side of LCD panel to prop it up. Fit perfectly and very sturdy. This gave me plenty of space to work with the replacement.

me too. All went well expect replace this flat cable which is tricky almost when my view is low and I've got big finger. I broke the cable end connector to motherboard but I don't know if I damaged the connector on motherboard. I'm waiting from Apple service for diagnostic.

I would suggest on the guide to add a step to explain how sensitive is to replace this cable. iMac should lay on the back and it should have some stuff to maintain the motherboard elevated in order to insert the display port flat cable to the motherboard on a less stressful way.

asthomas -

The ZIF display cable is tricky to get back in. I would suggest that this cable be the first one to be put back during reassembly. You need maximum wiggle room and visibility for this. Push in the display power cable *after* this one.

ganesh - Réponse

How do you get the ZIF connector back in? Some screenshot or instruction would be very helpful. I cannot get mine back in.

Brian Bowlin - Réponse

This is really difficult, but essentially it slides in - with no discernible click. A *slight* tug on the lever lets you know its connected. Horrible thing.

Use the ‘bic pen’ trick and you don’t have to remove this for most things but I had to go ‘back in’ to remove the super drive. I then used the tip next down and removed this connector at the screen also and put this end back in first with no screen in the way.

Jem Marsh -

I found the best way for me to reinstall the ZIF cable in was to lay LCD panel on its face and gently peel the black tape on upper part of lcd to expose and remove the connector there. At this point the ribbon cable is free and you can insert the hard to align connector to the board. Set LCD into imac and connect the small push connector next to the ribbon cable on board. It was easier to see and then reconnect the cable to the upper portion of LCD and tape it back over. Reinstall other connectors etc. This way worked best on my 27" iMac as it was much easier.

thewiseone71 - Réponse

The is a great tip

Jem Marsh -

I had to replace the cable due to damage from trying to reinsert it at the logic board and I found it best to re-attach it exactly the way that thewiseone71 describes it above. If you disconnect the part at the top with the tape around it, this goes much easier and there is less of a chance of damaging the port on the logic board where it attaches at the other end. I think some photos of this port, and the way this cable goes back in would be a great addition to this tutorial. Replacing this cable would also make a great tutorial.

What would be really helpful to this guide, and this image is the closest I can find in the sequence, is a quick summary of exactly where the diagnostic LEDs are on this model (and what they mean, although the latter is easily googleable). I only mention this as I believe my PSU is goosed as no LEDs are illuminated anywhere, however I can only find references to 2009 and 2010 of the similar MYs which evidently have diagnostic LEDs in a different place, hidden under tape, and I suspect numbered differently. So I can't be 100% certain!

FYI...I did this fix, upgraded my mid 2011 27" to a Samsung 850 EVO SSD Hard Drive. Everything went great except for two parts...

1. When I started up with my install media I got a three beep error and I could not install. I ended up using the CRTL-R at startup and did a network install that downloads an image of the original OS that comes with the system and allows you to install with the correct file.

2. Hard drive fan was spinning at full speed the whole time. This was annoying to say the least. Another person on this thread commented on this and said that you had to buy a $30 piece of software to fix it, I actually found another one that is free and works quite well (http://exirion.net/ssdfanctrl/).

There seems to be a missing step here. All the while one is removing the cables from their sockets it is supposed that the screen which is quite heavy is suspended in mid air… no, you are holding it up with one hand while doing everything single handed while in all honesty it would be nice to have both hands if for nothing else to steady your movements. So. Lets add a step. Lets figure out a solution and use some kind of prop until the screen is removable.

Note that if you are replacing the hard drive with a non-Apple hard drive, then you will have problems with the fan running full speed constantly (see http://blog.macsales.com/10206-further-e...). Basically, you'll need to either install a $30 piece of software to control the fans or short out some wires.

You don´t need to short out the wires, just install the free SSD FAN CONTROL app from EXIRION.NET und you´ll be fine :D

Martin Schober -

There are kits that have a thermal circuit and plug between the hard drive and cables to the 3.5" drive to allow other non-apple drives to be installed and still have the fans and diagnostics function normally. No need to short or modify fan speed with software that won't adjust for temperature properly. You just attach the thermal sensor to the drive and plug it in. Usually range from $50-$80 just for the cable, I'm really shocked I can't find them available from ifixit! Just ordered one from the US source.

FAN SPEED PROBLEM -> FIXED FOR FREE

When replacing HD with same (newer model) type and brand the fan-full-speed problem still occurred. Reason: All HD's not sold by Aplle Store don't have required special apple firmware to handle the Apple built-in fan controls. Fix: FREE program: http://www.crystalidea.com/products?ref=... Don't spend money.

OVERHEAT PROBLEM / CLICKING HD

My medio 2001 iMac heats more then box windows pc: large screen that generates heat very close to components. When you hear the HD "click click", it's safe to say your HD is running too hot. Play with settings in Mac Fan Control prog to find the "no click"-setting. Check manual HD.

SLOW MAC = HOT MAC = BURNING HARD DRIVE TOO MUCH

Macrunning slow? check available RAM in Activity Monitor. If it's less then 1 gig, by some more. Dead cheap at +- 50$ / 4 gig.

EU USERS OF IFIXIT

1) Google for iFixIt Europe to find a German based webstore.

2) Buy kit + the screwset, the screws are USA type.

It's dead easy, took me 30 min.

Good luck!

Question for folks. I have a 3TB drive (WD Caviar Green) that is out of an Apple Time Capsule (the wireless bit died) that I was going to put into my iMac. It's got the Apple logo on it. Does anyone know if this will work without needing the cable or special software?

I did this upgrade - Samsung 850 EVO SSD - Adaptadrive & Sensor. The computer won't start now - won't even try to start. I think that the connection at the very top left of the screen to the back might not be correct - it might be broken. How do I deal with that? I went to an authorized Apple store and they said they won't look at it because I messed with it on my own.

All I had to do was disconnect the vertical sync cable. I supported the LCD with 2 Bic pens and had great access to the hard drive. There was no fan control on the HD. Everything went back together and it works perfectly. It took less than 15 minutes from start of repair to reboot.

jwlussow - Réponse

Same for me, no fan control cable, and I even bought the part and had it ready! And I agree, removing the whole panel is overkill, once you get that thin top cable detached it will lift out pretty far and gives plenty of access.

The Bic tip is a great move… many thanks. My third time inside mine now as I try to resolve a random restart issue - fitted OWC sensor on 2nd time in but now I’m putting the old drive back to see if it still occurs.

Going to be under there again - so much easier with the Bics

Jem Marsh -

Took an hour because I was taking my time and blew out all the nasty dust that permeated the entire inside of the nearly 4 year old iMac. Used an AdaptaDrive with an OWC thermal sensor, and a Samsung 850 EVO 1TB. Unscrewed the pins on the drive and the bracket on top and attached that hardware to the AdaptaDrive frame. Cloned the drive ahead of time and when powered up, the thing screamed to the desktop. Fans are both sitting at ~1150 RPM. So, success!

cvolek - Réponse

Added new SSD in place of HDD. I used the method without removing screen, just removing first wire and supporting it on whiteboard markers. I had to drill an extra hole in the upper bracket because it's screw holes were too far away. I used regular 5.5mm drill head, and you can swap the rubber hole inserts to the new hole. It allowed me to easily add the SSD with simple ADATA bracket I got for free with my Samsung EVO. I know you can get 'the right one', but I did with what I had.

Thanks, this guide was PERFECT. I just installed an Intel 730 SSD and now my iMac is SCREAMING FAST. Nice tip on using the Dry Erase Markers to hold open the display so that you only have to disconnect the vertical sync cable. I used a short Torx to undo the HD.

I tried to install an SSD using this and several other instructions available online. All of the others did it successful and I did not. The installation on the physical drive was easy. Getting my iMac to recover is not. It doesn't respond to the recovery boot. I tried using a bootable usb drive and a fresh install of the OSX, but that froze at "one second remaining". I'm now attempting a restore from time machine, which surprisingly did start, but is so slow that it will take over 9 hours to restore (it's still increasing as I post this). Can anyone give advice?

Kryn Sporry - Réponse

Managed to succeed. Here was my situation:

My SSD was brand new and not initialised. Internet recovery wasn't possible as the iMac couldn't boot in recovery mode. I suspect this may be due to that bootable part being absent from the new SSD. Newer models may have a bootable partition in ROM, but my late 2009 iMac didn't.

I made a bootable USB drive on my MacBook Air. That allowed me to boot from the USB in recovery mode.

There I formatted the SSD.

I tried a fresh install of El Capitan, but as explained above, that failed.

I then tried booting from my time machine, which surprisingly worked. It only allows you to do a restore, so I selected the latest backup entry point (a few hours before I made the upgrade.

Restoring took about 9.5 hours, but this morning it had finished as the screensaver was on.

I logged on and it finished setting up my Mac.

The rest of the startup was a bit slower than expected, but I think it was faster than with the original drive.

GREAT! Replaced my HDD of a MID 2011 iMac 27" with a Crucial SSD 1 TB in 15 minutes (two people).

Performance is 100 to 1, this is really like buying a new iMac, but at 10 % of the cost.

Prior to replacing the HD I made a TimeMachine backup of my iMac and created a USB-Boot device for OS X Sierra.

After installing the SSD drive, boot up from the USB device and make a fresh install of Sierra. After this, connect your TimeMachine backup device (i used a 1 TB external USB HD) and use the Migration-Assistant from the Utilities Programs to restore the User/Apps/Data files from the Time-Machine Backup. The restore took about 5 hours (600 MB) because of USB 2.0 - so be patient.

This way you will end up with a FRESH IOS INSTALL and all your mail/settings/data/apps/fotos... from your TimeMachine Backup.

I absolutely recommend this upgrade because of the exceptional performance gains when using fotos, garage band, motion, final cut pro x, imovie - BIG SMILE!!!

...just do it!...

To get rid of the "HDD FAN PROBLEM" I installed HDD FAN CONTROLL app from EXIRION.NET. It´s free and does the job quite well!

Thanks for the instructions! :-)

I successfully swapped my iMac's original 1 TB Seagate HDD with a 2 TB Seagate SSHD and everything went smoothly. Prior to swapping the drives, I cloned my original drive to the new drive using Carbon Copy Cloner (https://bombich.com/). After I installed the new drive, my iMac booted up with no issues. I noticed my fan was running continuously so I installed the SSD FAN CONTROL app from EXIRION.NET. I ran this app and set the Hard Disk fan to SMART mode and the fan slowed down to a quiet speed.

Replaced broken stock drive with 2TB Western Digital Gold and OWC In-Line Digital Thermal Sensor HDD Upgrade Cable for iMac 2011 (model # OWCDIDIMACHDD11) using this procedure. You definitely do not need to remove the whole screen. Just lift the top edge, remove a single cable (the vertical sync cable) and then prop the screen up on both corners - the idea of using two BIC pens worked for me. All worked fine, no fan speed issues.

Hi, I've three questions:

One, if one is putting in an SSD is replacing the EMI foam necessary? One, it won't touch the chassis with an SSD mounted, and, I wonder if it's only needed for spinning drives?

Two, when replacing drive and using the OWC/MacSales thermal connector cable. getting that cable tucked in inside the inner frame, it's difficult to do without dislodging the wireless antenna connection leads. Is there a trick to doing this without knocking one of these sensitive lead connectors off?

Three, the display data (ZIF) cable seems somewhat imprecise to reconnecting it. It's not a positive click or lock into place. I'm sure the metal clip that retains it needs to be pushed back down, but it's reseating seems so tenuous that I usually boot the computer up before screwing down the display, just to make sure it works. Is there any sure fire way of making sure this cable is reconnected right when putting it back together? The other cables all seat nicely and you know they are either connected or not

Replaced the original apple 1TB WD drive with a Seagate 5900rpm 4tb hybrid. Excellent instructions. Quite easy to do. No issues with the fan.

Hello folks, my old SSD go down and I replace it with a new one (WD WD10EZEX Blu Hard Disk Desktop 1 TB, 7200 RPM, SATA 6 GB/s, 64 MB Cache, 3.5").

Now I’m trying to install the new OS with a USB pen with Install Disk Creator, I restart the Imac, hold down the Alt button and appear a message like “there is no space to install..”

What is wrong? I'm afraid it is not recognized the new SSD…

There are someone can help me?

Solved! I restarted my iMac again, without USB pen drive. It works!

Hi Folks, This was indeed an easy install. The instructions are great.

Unfortunately, after installing a fresh copy of High Sierra on my 2011 iMac, none of my “mice” will allow me to click anything.

Any ideas why?

Here’s some “low hanging fruit” to get out of the way before considering the more mysterious possible causes. Do you have any Bluetooth input devices like a mouse, trackpads or keyboard in the vicinity of the computer? If such items are powered on, they can interfere with even wired mouse clicks. Remove their batteries and wait a few seconds and then see if your mouse works.
