Mac Mini Model A1176: Can I convert the power supply to USB-C?

Tue, 20 Jan 2026 00:37:12 -0700

Hello everyone. Since I lost the power supply to this old beast, I started wondering if I could switch the proprietary connector to USB-C?

From what I searched, USB-C doesn't handle the max power output of the original, which is aproximatly 19V/6A, and I also can't find any diagram or pin layout of the connector, which is a shame. Even if it is slightly underpowered, can it run normally?

Mac Mini Model A1176: Mac Mini not POSTing, Fan spinning at full RPM.

Fri, 14 Nov 2025 06:33:11 -0700

My Mac Mini is not POSTing; It's spinning the fan at full RPM and not turning on when I plug in the power adaptor. I tried everything: keybinds, CMOS battery stuff, and clearing the power (by holding the power button while it's not connected). I tried to see if the 5V rail works at least by plugging in a charger that has LEDs in it, and it started lighting up (and charging my phone), if that's useful.

Mac mini Model A1176: Max amount of Memory A1176?

Fri, 06 Jun 2025 07:15:02 -0700

I know that the Max memory on the original 2006 model mini's is 2 GB. However on the later 2008 model mini's it's 3 or 4 GB. Is there anyway to make an early model mini use 3 or 4 GB?

Seeing as they use the same chipset in theory it should be possible.

My guess would be it's a firmware issue?

Mac Mini Model A1176: Mac Mini A1176 power LED stable but no other signs of life

Fri, 06 Jun 2025 07:00:25 -0700

Hi,

I tried to power on my mac mini A1176 today after it's been in the garage for a couple of years, the white front LED comes on and stays solid, but there are no other signs of life - no video, beeping, flashing LED, fans spinning etc. So far I have tried:

Multiple displays and cables.
Strip all parts down to and including CPU.
18.2v off the PSU on my multimeter.
Replaced PRAM battery.

No matter what I do to this machine, I get nothing apart from the solid LED light. I can hear a really really quiet high pitched whine coming from the CPU though. Any suggestions will be gratefully received!

Mac Mini Model A1176: Cannot boot into Mac OS X on 2007 Mac Mini

Mon, 10 Feb 2025 10:46:35 -0700

I'm having an issue with a 2007 Mac Mini I recently purchased on eBay. When I first received it, the Mini was working fine. I replaced the internal drive with an SSD, installed 10.6.8, booted it up and all was well. My problem started when I tried to use Boot Camp. When I started the process, the Mini instantly rebooted without giving me the option to partition the drive or anything. I exited the Windows installer and rebooted the Mini to try to go back to OS X but it would not boot into OS X and none of the keys would work to enter recovery or choose boot options. I eventually removed the drive, wiped it with another computer and put it back in but that didn't work either. I then went ahead with installing Windows to see if that would allow me to use other boot options but after successfully installing XP I still could not go into recovery mode or choose boot options.

Is there any way to erase and reinstall the latest OS my Mac can handle? I tried deleting via disk utility but it is greyed out. I've tried command R and Alt+Command+R and nothing, it just starts up as normal. I just want to wipe it! Does connecting the Mac to ethernet do anything regarding this? HELP

Mac Mini Model A1176: Can I use a zip tie to replace the pin?

I was wondering I broke one of the heatsink hold-down pins in my mid-2007 Mac mini and I was wondering if I can use a metal screw that’s a 4-40 3/4 screw to replace the plastic pin? Or if not do I need all four or can I just use three pins instead of all four pins?

Mac mini Model A1176: Replacement heatsink hold-down pins?

Tue, 01 Nov 2022 22:33:36 -0700

I need replacement heatsink hold-down pins (spring loaded plastic pins) for the CPU heatsink on my A1176. On the second CPU upgrade the one-way ends (under the logic board) snapped off two pins despite careful handling.

I don't want to buy a whole $100 dysfunctional mini on eBay just to get heatsink pins! I came up empty with Digi-Key and other component suppliers. Anyone have any ideas?

Mac mini Model A1176: Sourcing chassis screws for Mac mini

Thu, 22 Sep 2022 12:24:19 -0700

Hello ifixit... I need to source the chassis screws (4) that hold the main assy to the base. An authorized repair outlet that I foolishly permitted to work on my Mac mini didn't reinstall them - threw them out! They actually told me that they're not needed, to which I immediately deleted them from my rolodex... Please tell me you at least have some sort of 'screw kit' for the Mac mini? Trying to find them is a major pain... Pls advise. Thanks in advance. Chas Hulme

Mac Mini Model A1176: Mac Mini Not Booting / CPU fan starts then doesn't turn off

Sun, 14 Aug 2022 23:17:10 -0700

Whenever I plug in the Mac Mini the Fan continues spinning but no signs of life in any sort of way. No LED indication or display on screen. I did a CPU/RAM Upgrade about a year ago and it worked for a month but after I did a disassembly I resembled the computer and it stopped working. It could be a power supply issue but I still have no idea , wasn't gonna take it to get repaired because this is my personal project computer. Any help or tips would be greatly appreciated …… Thanks IFIXIT :}}}}

Mac mini Model A1176: Mac Mini light comes on, but no chime.

Tue, 19 Apr 2022 22:47:55 -0700

I purchased a 1.66 Core Duo mini early last year, ran sata out the side, and upgraded to a T7200 processor. Over the past month, I got a couple of lockups under load (importing CDs), and once a GSOD.

Last week, I woke up to find my mini completely dead. The power light was still on, the hard drive was still spinning, but nothing going on. I powered it off, and back on, and it still sat silent. The light came on, but no chime, and no booting.

What I've tried so far:

- resetting the PRAM => fan runs @ max until I turn it off, front light does not come on.

- resetting the SMC => back to the normal state where the front light comes on, but nothing else.

- replacing the original 1.66 Core Duo CPU to see if I'd smoked the T7200.

- pulling one of the 1G chips out, and then the other.

At this point, is there much chance that it could be anything but a failed logic board? (The thing was quite dusty around the intake vents ...). I suppose it could be the power supply, but it seems sort of unlikely.

Nobody seems to sell logic boards, so I guess it's time to pick up the cheapest old mini I can find ($350 is what I've seen), or fork over ~$750 for a brand new one.
