    • La tarjeta AirPort/Bluetooth, que cumple con el estándar Wi-Fi 802.11ac, aún se adhiere a la parte posterior de la placa lógica, lo que hace que el reemplazo no sea más fácil que antes.

    • No es la primera Mac que se actualiza con el nuevo estándar ac, esperábamos ver un hardware similar al de las MacBook Air actualizadas de principios de este año.

    • Quita el bloque nuevo:

    • Broadcom BCM4360KML1G 5G WiFi 3-Stream 802.11ac Gigabit Transceiver: como se esperaba, este es el mismo chip que impulsa el Wi-Fi de CA en el MacBook Air de 11" y 13".

    • Skyworks SE5516Módulo frontal WLAN de doble banda 802.11a/b/g/n/ac

    • Solución Broadcom BCM20702 Bluetooth 4.0 HCI de un solo chip compatible con Bluetooth Low Energy (BLE)

    Replaceable Wifi card is excellent news. Question: is it possible to upgrade the WiFi card to 'ac' in previous Late 2012 iMac? If so, where can I buy that part?

    • Como ahora es estándar en todos los nuevos iMac, el nuevo iMac de 27" incluye soporte para almacenamiento flash basado en PCIe. Esta es una sorpresa agradable en comparación con el modelo de 21,5" del año pasado, cuando nos quedamos muy decepcionados por las almohadillas de soldadura despobladas en nuestro bajo placa lógica final.

    • Según Apple, la inclusión de almacenamiento flash PCIe permite velocidades hasta un 50 por ciento más rápidas que la generación anterior.

    • La opción Fusion Drive combina la gran capacidad de almacenamiento de un disco duro con el alto rendimiento de la memoria flash para ofrecer tiempos de arranque más cortos y un acceso más rápido a aplicaciones y archivos.

    i jst want to know if i can upgrade my graphics card to NVIDIA GeForce GTX 780M with 4 g.b memory,, is i ?!

    gforceemas - Contestar

    I would like to know, do they sell a ssd that can fit in that slot in step 4.

    Is it m.2 or mSata?

    Where can I purchase the SSD to utilize that slot?

    • La actualización del iMac de Apple incluyó algunos cambios furtivos en el modelo de 21,5", y estábamos más que un poco perturbados al descubrir una CPU soldada.

    • Afortunadamente, su hermano mayor de 27" se salvó del mismo destino, y los usuarios avanzados aún podrán actualizar su procesador sin un horno de reflujo.

    I've never heard of anyone buying a Mac expecting to upgrade the CPU (or ever having to replace one).

    Scott Adams - Contestar

    Not to mention that the reason the CPU is soldered in the 21.5" iMac is because it's the only formfactor Intel sells the CPU in with the Iris Pro graphics. You CANNOT get that chip with a socket. No way, no how.

    Given this iMac does not need the Intel graphics, Apple went with the traditional socketed design.

    Blame Intel for that one, not Apple.

    (Though I agree - do people really upgrade their CPUs? Short of enthusiasts who upgrade every 6 months (who would never buy an iMac anyways...), by the time one finds the CPU too slow, it's time to upgrade the entire machine anyhow. Even on a PC you'd probably have to replace the motherboard, so soldered or not...).

    Do we know which i7 they're using in the 27"?

    Daniel Gray - Contestar

    can i put this wifi card in my 2010 imac 27 i7 2.93 ghz?

    jess - Contestar

    I've done it before. If you're happy with the shell it's a great way to spend 10% of a computer's replacement cost and still enjoy a generational leap forward in performance. Made my G4 last 10 years that way through RAM, Graphics Card and Processor upgrades. This is the same thing. I bought a Haswell iMac 27 only because the screen is so much better than my iMac 24. Otherwise I would have figured out a way to stretch my $2400 investment from 2008. Did the same with a Macintosh Plus too. Well a 2 Mb upgrade and cutting the 256k resister. Still. I've always enjoyed messing with out of the box items.

    • Circuitos integrados pesados:

    • Procesador Intel Core i5 de cuatro núcleos a 3,2 GHz

    • Concentrador de controlador de plataforma Intel

    • Como se anuncia, el iMac 27" ahora tiene un nuevo y elegante procesador de gráficos:

    • GPU NVIDIA GeForce GT 755M

    • Cuatro circuitos integrados SK hynix H5GQ2H24AFR 256 MB GDDR5 SGRAM conforman 1 GB de RAM de gráficos

    Good day!

    Is there any information about which exactly north bridge is installed on this model (ref to: Intel platform controller hub)?

    Today I got my iMac 1419 from non-official service and noticeably work slower and image update very slow on the screen compared to late 2011 iMac sending next to this one.

    Hola Tocayo, excelente explicación pero me podrìas orientar de como quitar el CPU, lo quiero actualizar a un core i7, gracias

    • iMac 27" EMC 2639 Puntaje de reparabilidad: 5 de 10 (10 es el más fácil de reparar)

    • La memoria RAM es reemplazable por el usuario sin abrir la carcasa, gracias a la puerta de acceso posterior.

    • Todavía puede reemplazar el disco duro y la CPU dentro de esta máquina, aunque con algunos cortes adhesivos.

    • Los componentes son modulares y bastante fáciles de quitar.

    • Las personas con presupuesto limitado ahora pueden agregar un segundo disco duro al iMac base porque el conector Fusion Drive ya no falta en la placa lógica.

    • El vidrio y la pantalla LCD están fusionados y ya no hay imanes que mantengan el vidrio en su lugar.

    • Tendrás que despegar magistralmente la vieja cinta adhesiva de doble cara y aplicar cinta nueva para volver a sellar este iMac en su estado original.

You forget to mention *HOW* one should mount an extra SSD in the new port.

Do we need to remove the LCD panel or is there a slot you can access through the back, like with RAM?

Christian Bille - Contestar

You'll need to remove the LCD and dig your way inside.

Miroslav Djuric -

On the BTO "SSD flash memory only model", is the SSD connected to the rear PCIe port leaving an empty SATA port? So someone could add an additional SATA drive?

Thx

Matthias Gasser - Contestar

I am also looking for the same info. Anybody has an ans?

imacsps -

Is the Thunderbolt port "Redwood Ridge", ie. DisplayPort 1.2 capable?

Robert Le - Contestar

Thanks for the tear-down...very nice as usual.

I'm glad we can still easily upgrade RAM on the 27" iMac. I would still like to be able to easily upgrade the HDD and/or SSD though - especially as SSDs get cheaper.

Scott Adams - Contestar

What we be required to install a second drive? I would like to keep the stock 1tb hdd and add a Samsung S30 SSD.

John - Contestar

Has discover how to add a second drive? thanks

janomixchile -

Do you think the cooling would support a 3 or 4TB hard drive and a 256 or 512GB SSD?

FredR - Contestar

1) In order to "upgrade" the CPU, would you just "pop out" the current i5/i7 and plop a new one in? Are some not going to work? Would you need to do any software upgrades, etc.?

2) Same sort of question regarding the fusion drive slot. Would this only work with an apple fusion flash drive? could you just plop in a samsung, etc SSD? Any max for storage space?

Ali Maadelat - Contestar

There is no "popping out or plopping in" a replacement processor in this or any other iMac, save for some of the earliest G3 and G4 machines. If you're going to upgrade your processor then plan on replacing the mother board complete, and then only the particular board that fit into the same model machine. This is the only way an upgrade can be achieved without a lot of 'board level' experience, the sort that won't be addressed here. Popping and plopping is saved only for various PC variants but then we don't see much in the way of generic and mundane in the Mac world.

Eric Haulenbeek -

Ok just tore mine down thinking I could easily add a SSD drive to my 1TB sata setup. NOT. There is NO additional SATA port and the one that's on the MOBO is proprietary to Apple. So unless you have a converter that can adapt a STANDARD sata cable and power, then adding your own "Fusion Drive" setup is not going to happen. However, if you bought the SSD model then you can add the additional HDD but would still need to split power from their proprietary power cable. UGH.

Michael Ybarra - Contestar

Is the GPU upgradeable? Can I swap a GeForce GTX 780m for the base 755m card?

California Aggie - Contestar

Does the fusion drive have a PCIe SSD and a standard sata HD or is it a special drive? Can it be splitted into two individual drives again?

Thomas Mosch - Contestar

This information is wrong. If you order the iMac with a fusion drive then the logic board has an SSD slot. If you don't order it with a fusion drive, it doesn't have that slot. Please correct your article.

Thor - Contestar

Eric Haulenbeek.... I just hate it when people spout off things as if they were gospel when they have no friggin' idea what they're talking about. Case in point: your assertion that you can't upgrade the CPU in these Macs without board level tweaking. Utter nonsense! Pick a CPU that will fit the same socket and TDP and you're in business. To be safe, you should pick a CPU that Apple has already installed in the same model so that the firmware will support it. For example, you could replace the 3.2GHz Core i5 4570 with the 3.5GHz Core i7 4771. Whether this would be an economically wise course of action is another question.

Is it possible to install 2 ssd in raid 0 in a imac 27" late 2013. I have the one that comes with 1tb of hdd.

gera07 - Contestar

I have a mid 2010 iMac 27, containing internally a 2TB conventional hard drive, and 240Gig SSD drive replacing the DVD drive. I’ve been offered an iMac 27 late 2013. Is there merit in swapping into it the 2TB and SSD drives from my 2010 model. Is there room and connectors to make this possible? Thoughts of others?

Regards,

Terry

Terry Smythe - Contestar

It’s been a year since you wrote this… great time to use a Big Sur hack… the 2013 I just acquired doesn’t have a SATA port installed. But Amazon and eBay had one. Pull the logic board and hook it up. Then enjoy the extra data connection. Nvme to apple SSD adapter works with no sleep wake issues.

Pete Karnowski -

Did a CPU swap to a Xeon 1231 v3… thus far it will not POST or turn on. It leads me to believe/hope I didn’t connect the power supply well. I’m a little exhausted this was a rigorous job, tomorrow is another day. Insights welcome until then.

Pete Karnowski - Contestar

Got back in, bent some CPU pins…. daintily put them back. Go for boot. Recommendation remove the plastic ram cage and start reattaching the CPU from the side closest to the edge. I can’t confirm the Xeon didn’t work, I didn’t see a point in testing too variables for repair and another surgery afterwards.

Pete Karnowski -

Rather than change parts and replace thermal paste to the heatsink and CPU, can I buy a new logic board?
