iMac Intel 27" EMC 2546: Why is my iMac Intel 27" startup drive missing?

Mon, 27 Jul 2026 14:17:21 -0700

My 2012 iMac fusion drive stopped loading. In recovery, I can verify the disk but not repair. I can see both drives but can not erase or reformat. Both drive names appear in red. When I attempt to reinstall Catalina I get the message "This disk doesn't use the GUID Partition Table Scheme." It's like the drive disappeared. Has anyone seen this before I may know what my options are? Thank you in advance.

iMac Intel 21.5" EMC 2428: Alt/Option not opening recovery mode

Fri, 24 Jul 2026 10:34:26 -0700

So I while trying to install Linux Mint on my iMac, I accidentally deleted my Mac OS partition and recovery partition. I want to go back to High Sierra, which I was using before, but was only able to create an El Capitan bootable USB through the official Apple page.

I have now created a flash drive with Mac OS El Capitan on it, but when I start the machine and hold down Alt on my keyboard, it boots straight into Mint and does not let me select the installer USB.

Any idea what's going on?

Mac Studio 2025: Not teardown? No guides?

Sat, 18 Jul 2026 02:34:25 -0700

Hello,

It has been half a year since the release and still there is no guide available for this.

That's weird, I thought the only purpose and business of ifixit was exactly doing this, and there is still no effort put into this.

Is there any plan for it? I am really looking forward to see it, and decide if I am getting a Mac Studio M4 for that reason... or not.

Thanks

iMac Intel 27" Retina 5k Display: What is the display connector part on a late-2015 iMac?

Mon, 13 Jul 2026 11:39:57 -0700

I have a late-2015 iMac 5k with a broken display. It looks like the previous owner broke a couple pins on the logic board connector based on the couple missing pins on the original LVDS cable. Even when I connect a working display using a new cable it doesn’t function.

It’s not the display or the cable as I’ve tried both on another iMac 5K.

I’ve seen this (the logic board connector) referred to as a LVDS or a special eDP connector.

*Where can I buy this? And can I find someone to solder/replace it for me?

I’ve also tried reseating the cables with no luck. Is there something else I could try?

It’s one of the i7 models with m395x. I’d hate to junk it.

Mac Mini Late 2012: Mac Mini not booting, white led blinks, fan spins briefly, no chime

Sat, 04 Jul 2026 16:37:39 -0700

I'm having an issue with this model (intel i5, 4GB DDR3 ram), where it starts up, white led turns on for a while, fan spins up briefly but the mac mini does not turn on. This process repeats forever.

I've removed the power supply and I'm measuring the voltage. With no load, they all read 11.88V (any of the right pins with any of the left pins). Then I press the switch on button, all pins go down a little (like 11.82V) but the rightmost left pin + any of the right pins read ~9.22 for one second, they go up to 11.88V, then down again, then up and down, etc.

In a picture I've found on the internet, this "rightmost left pin" is marked as ground.

The point is: is this behavior right? Should the ground pin have 12V, 0V, or what?

Ps.: I'm from Brazil and English is not my first language.

Red: negative pins
yellow: neutral (? maybe not) pin
blue: positive

PSU details

Model details

Voltage reading between any one positive and one negative pin

Voltage between neutral and any positive pin when computer is trying to boot up. The reading fluctuates between 11.8V and 9.2V consistently - i.e., when trying to boot up voltage goes down, fan spins briefly, stop, voltage goes up, rinse and repeat

Reading between any negative pin and neutral pin when the process described above is happening. Voltage goes from zero to 2.5V at the same time the above process is going from 11.8V to 9.2V

Demonstration of how I'm measuring things. In this example, one negative pin (black probe, left), one positive pin (red probe, right)

mobo for reference (side 1)

mobo for reference (side 2)

Extra information: all tests were done with RAM installed and with no RAM installed, same results. Also, sometimes, for no clear reason (at least to me), after probing the mobo randomly with my multimeter (hoping some fairy could tell me what's wrong :-D ), the mini boots up - I hear the chime. But after turning it off and then on again, the miracle stops working.

iMac Intel 21.5" EMC 2308: LCD Backlight not working = solved

Sat, 27 Jun 2026 12:28:13 -0700

Hi,

I have an iMac 2009, 21,5" which has been working well until last week. First there was some flickering and sometimes a black display. Since yesterday the display seems not to work anymore.

I have found the apple technicians guide for this iMac online and tried some of the solutions described there. I did a SMC/PVRAM Reset, but this did not solve the problem.

To determine if it's the gpu I connected an external monitor -> everyhing working fine on the external monitor.

It seems that the LED backlight isn't working anymore, because if you use a flashlight you can see everything on the internal screen.

I asked at a local repair store but they told me (without looking at the device...) that it was either the LCD panel, which would cost almost 500€/650$ to replace or the SATA/Board (Logic board?) which would even be more expensive.

My question is whether it's possible to determine if it is the logic board, ta cable connection, the Backlight controller or the LCD-Panel.

Thanks fpr your answers,

Max

Hi all,

I deconstructed my iMac and made it into a functioning external monitor after it broke.

I want to re use the iSense camera by making it a USB device. I have heard of people soldering the cables onto a USB for use. The issue is, there is 7 wires and I am not sure which wires to attach to the USB as they only have 4 connections. I have attached an image.

Mac mini (2024): USB-C broken no connectivity on any usb-c port.

Mon, 15 Jun 2026 06:26:18 -0700

As per title. I've tried the various troubleshooting steps (holding the power button down to get to the boot select, however can't do anything as it won't recognise any keyboards/mice). I've tried multiple mice/keyboards and nothing works. It's like the ports aren't supplying power at all. It's been running happily for a while since I bought one when they came out (like within a week or 2 of launch so it's likely well out of warranty now). Are there any troubleshooting steps that I'm missing? I've tried to find support articles on this but they all refer to the SMC reset but that's irrelevant for this machine as they don't have it. There is no power draw on the usb-c (every single one) so I'm assuming it's a fuse that's gone somewhere? I want to exhaust all options before getting it under the microscope. It still boots but can't do anything with it, I'd happily use it as headless machine in my homelab even if the usb-c is toast. Is there a way to remote log in to the machine. It has RDP enabled but since power cycling it I can't seem to connect as it's waiting for a user to log in. This was the primary way I was interacting with the machine before the USB-C died anyway.

iMac Intel 21.5" EMC 2428: Can a 21.5" Mid-2011 iMac be upgraded to an i7 2600?

Sun, 14 Jun 2026 02:13:34 -0700

So my iMac is a 21.5" iMac from Mid 2011 with a core i5 2400S as default, now I know you can upgrade it's processor since it's socketed and that's just what I'm going to do.

But what I don't know is if I can only upgrade to a low power chip (S suffix) or if I can upgrade to a full power desktop chip (no suffix). I've seen people upgrade their i5 2400S 27" iMacs to i7 2600, but I've never seen anyone tried a CPU upgrade on a 21.5" imac before let alone the highest end CPU offering from Apple on the 21.5" Mid-2011 iMac is only an i7 2600S.

Now the performance difference between the i7 2600S and i7 2600 is negligible for me, but the problem is I can't souce any i7 2600S but I can fine loads of people selling their i7 2600.

So if anyone can answer, please do as I will apreciate it greatly and if anyone is selling or knows someone who sells an i7 2600S that can ship to Indonesia please answer too. :) Thanks in advance.
