Can I upgrade the processor to C2D Extreme X7900 @ 2.8GHz ?

It's all ok! :-)

I work with iMac 8 hours per day and don't have any problem!

It's totally recomended to change the CPU ! I install Lion and works perfectly.

I'm using an Intel based iMac (Mid-2011 model) 21.5 inch. It comes with a 500GB hard drive (ST3500418AS) and I'd like to replace (not add a new drive by removing the optical disk drive) that drive with an SSD (Samsung 840 EVO-Series 1TB 2.5-Inch SATA III Model #MZ-7TE1T0BW)

SSD link below:

http://amzn.to/1Ea56Ok

the ssd itself is 2.5 inch and I'm going to convert that drive to 3.5 inch drive by using a WD icepack which is sold on amazon.com for about $20 usd

WD Icepack link below:

http://amzn.to/1rITB9O

first I'm going to attach the ssd into the WD icepack and then I'm planning to replace the original HDD that comes with the iMac by installing the SSD.

My questions are:

1. does apple allow 3rd party SSD's for iMac?

2. do I need any additional cable kit?

3. is it enough to change just the drives? (I mean HDD comes with a termal sensor, does the SSD need a termal sensor?)

4. do I need any software after installing the SSD (if possible) to control iMac's fan speed [I heard some people complaining about their fan speeds and the loudness of the fans]

Does anyone see any problem with this being able to work after the upgrades are in place?

So with the macOS 10.12.4 beta 1 and beta 2 the iSight camera doesn't work on our 2007 iMacs. It shows up in hardware but won't turn on. I am working on how to fix this.

Also, If you want Night Shift to work on our iMacs you can use clover boot loader with a smbios to trick the iMac into thinking it is a late 2013. You will have to apply a fix for USB because changing it to a late 2013 iMac smbios breaks all but one USB and also bluetooth (which is considered to be on an internal USB port) the patch that I have fixes all this. If anyone is interested let me know and ill make a right up.

I’m thinking of making some videos to post on youtube at my channel Nandor690. I do AppleTV stuff right now but I think I'm going to also get into making videos on hackintoshes and unsupported real Macs as well

I have figured out how to get Night Shift to work natively (Without using clover or doing any crazy hacks). Ill be posting a write up on this thread.

I'm still working on getting iSight working on 10.12.4 beta 1 and 2. Will keep everyone updated.

What I am working on now.

As you know, macOS 10.12.4 comes with the new feature Night Shift. But it doesn't work on our iMacs because they don't support Metal. late 2012 iMac is the first year for that.

I used Clover boot loader to make a smbios for a 2012 iMac and now my iMac thinks its a 2012 and night shift works!

A few draw backs are

• 2 of the 3 USB ports don’t work
• Bluetooth doesn’t work
• iSight camera doesn’t work.

I am working on fixes for these now. (Remember, those things don't work because I made my iMac think it is a 2012 instead of a 2007. NOT because I updated to 10.12.4. It is safe to update.

I’ll report back when I have fixes ready. I plan on setting up a couple threads in different forums and will link them here for you guys

Hello Mayer, at last I received the Power Supply yesterday and I assembled it a minute ago. My iMac is back in service! for a few seconds I was afraid of pushing the button and not hearing the chime... but there it was. Thanks again for your help, and thanks also to the members and participants of the ifixt it site.

So my Hard Drive Fan will run the full speed after 10 mins when I power on.

I google the solution and someone suggest that I can jump the connector to make the sensor short then it will show 0 C degree.

It works but I afraid the Hard Drive will overheat when I use for a long time.

Do you have any solution to solve this problem?

Thank you.

But while trying to close the iMac screen, all adhesives lined up, I connected the display's power cable and ribbon cable. Mistakenly, I lifted the display while trying to align bottom and ouch....the ribbon cable (vsync cable??) pulled out from its connector argh.....

I connected it back and closed the iMac. When I powered up there was a green vertical line (which was gone after a min) and the gray/black thick stripe about 1.5inch wide. This stripe stays all the time from boot to shutdown.

Tried SMC reset, PRAM reset... no luck.

I doubt the ribbon cable damage (is it vsync cable)...now I'm skeptical to reopen to play around without knowing what could be the issue.

Many questions on my mind....did I damage the display? Is the ribbon cable replaceable (I tried googling for spare part couldn't find a proper lead)?

Any help would be much appreciated thanks.

Finally fixed the expensive mistake :)

Had a local shop fix my system in Dubai

Also the iFixit adhesive strips and the removal tool are a must have!

Can I swap out the original wifi card for an Intel 7260 card that gets 802.11ac? The connectors look the same but the intel card has Bluetooth on it as well, would this be an issue?

I run nothing but windows on my imac now.

It sure would be nice to get gigabit wireless as I am upgrading to an SSD hard drive.

Thanks in advance!

is it possible to change the 1 TB HDD for a normal SSD Drive (like an 2,5" Intel SSD)?

I wanted to bring this question back up because I'm working with Miro to do a tear down and repair manual on this machine. We don't have one. I still don't have an answer that I know for sure will work and wanted to bring it before the attention of possibly some other contributors. I've subscribed to the Apple thread on this problem with no results. Any ideas? Thanks.

Need some help please! I woke up one morning recently to find my iMac was dead to any input. It was working fine the night before, I didn't shut down and just let it go to sleep on it's own. There is zero response when the power button is pressed, no boot chime, no screen response, no fans/hard drives spin… nothing.

What I've tried so far:

• Different power sockets, different power lead
• Reset SMC
• Replaced PRAM battery
• Replaced iMac power supply
• Removed graphics card

There is only one diagnostic led lit on the logic board (labelled LED601) when the iMac is plugged in:

There are 4 LEDs in total and it's the led furthest from the board edge that lights up. Strangely the service manual for this model seems to list the LEDS in an opposite order to my board:

I assume the LED that is lit up must be LED 1? ( indicating that trickle voltage from the power supply has been detected by the logic board).

Does this mean that it's most likely a logic board fail? why would the logic board suddenly fail overnight when iMac was sleeping?

Took it to the Apple store for a repair. As the machine displayed these unexpected shutdowns while at the store they replaced the logic board and the power supply. Machine worked fine for a few weeks and then started shutting down unexpectedly again. Back to the Apple store again where this time the machine apparently ran fine for one week without any problem.

Back home within two hours started shutting down again, now every two minutes, so unusable. Does anybody have any idea what could make the SMC shut down the machine? Is it a (false) high temperature warning?

Which other part might need replacing?

Could there be another problem causing damage to the logic board and/or power supply?

⟐ Answered Şubat 16, 2024 at 12:07 GMT-7

My first thought is blown power supply. Second, damaged motherboard. Need info. on diagnosis procedures, repair, ect.

These questions are very important to me:

• The HDD is upgradable without needing a thermal sensor?
• Is the CPU upgradable?
• Number phases CPU? GPU?
• Model number memory GPU ?

Can I update my CPU i5 3.8 (7600k) with i7 4,2 (7700k), the phase corresponding in watt?

Thank you in advance.

⟐ Commented Nisan 23, 2021 at 7:49 GMT-7

Only the first diagnostic led is on when connected to power. Nothing happens when i press the button.

Does this mean my logic board is broken? Cause replacing that is way to expensive.. :(

I need to be 100% sure that if the information it's correct. I want to place a PCIe SSD blade to my Imac but I would like to know if any of the below options works for my IMac, if you agree with the following information please let me know:

1) Apple SM0512F or SM0256F SSD PCIe blades are the same Samsung blades models MZ JPU512T/OA6 (512GB) and MZ JPU256T/OA6 (256GB) respectively.

2) Those blades are used and compatible with the following models:

• MacBook Pro (Retina, 13-inch, Late 2013)
• MacBook Pro (Retina, 13-inch, Mid 2014)
• MacBook Pro (Retina, 15-inch, Late 2013)
• MacBook Pro (Retina, 15-inch, Mid 2014)
• MacBook Air (11-inch, Mid 2013)
• MacBook Air (11-inch, Early 2014)
• MacBook Air (13-inch, Mid 2013)
• MacBook Air (13-inch, Early 2014)
• iMac (21.5-inch, Late 2013)
• iMac (27-inch, Late 2013)
• iMac (Retina 5K, 27-inch, Late 2014)
• Mac Pro (Late 2013)
• Mac mini (Late 2014)

Am I right?

If yes, these blades would work for IMac 21,5" and 27" Late 2013 and 2014.

I just need to be sure before I buy some used pulled from a Mac lap-top
