EDIT - (Easter-Egg 2026):

“We’re raising the flag of history !”

This build honors a quiet revolution. In Cambridge, Acorn’s ARM2 (1987) introduced a low‑power RISC design in the Archimedes
that shaped a generation of British computing. Apple’s early collaboration and investment in ARM technology for the Newton helped
commercialise the architecture. Although Acorn itself faded from the market by the late 1990s, its ideas endured - now powering the

modern ARM‑based Macs and millions of ARM-devices (Android etc.) we use every day !

In the mid‑1980s a small, determined team in Cambridge set out to solve a practical problem: how to build a fast, efficient processor

without the complexity and cost of mainstream chips. The result was the ARM concept and the production ARM2 CPU, which powered
the Acorn Archimedes - a machine that arrived in 1987 and stunned observers with RISC performance in a home/workstation form factor.

Acorn’s machines became a cultural fixture across the UK education system, shaping a generation of programmers and engineers.
Yet outsidethe British Commonwealth the company’s footprint was small - in the United States and much of continental Europe
Acorn remained largely unknown, which helps explain why its name is unfamiliar to many younger Apple users today !

Apple’s interest in low‑power RISC designs led it to collaborate with Acorn and others, helping to form the commercial path for
ARM technology.
Apple’s early investment - driven by projects like the Newton - seeded a technology that would, decades later,
become central to Apple’s own silicon strategy !

The rise from Newton to the modern M‑series chips is a story of patient engineering and strategic foresight.


From Cambridge to the Mac:
Acorn’s ARM2 (1987) seeded an architecture that powered education, inspired Apple’s early RISC work
for Newton, and ultimately underpins today’s ARM‑based Macs.

Acorn’s role:
Acorn Computers developed the ARM architecture and shipped the Archimedes family in 1987, the first
widely known RISC‑based home computer.

ARM: The ARM2 was the first production ARM CPU used in those Archimedes machines and established
the low‑power, high‑efficiency design that later scaled massively.

Apple’s early involvement: Apple joined Acorn and VLSI to form Advanced RISC Machines (ARM Ltd.) in
1990, investing to secure a low‑power CPU for the Newton project.

Acorn’s market footprint: Acorn was primarily a UK institution - its machines were ubiquitous in British schools but rare
in the US and much of continental Europe, which helps explain why Acorn is little known outside the Commonwealth.

Company fate: Financial troubles led Acorn to close its workstation division in September 1998 and the company was
effectively dismantled by 1999.


  • 1983–1986: Acorn designs the ARM concept in Cambridge.
  • 1987: Archimedes & RISC-OS (Arthur) ships with the ARM2 CPU.
  • 1990s: ARM becomes a commercial venture with industry partners; Apple invests for Newton‑era CPUs.
  • 1998–1999: Acorn’s workstation division closes; the company dissolves while its ideas continue.

Hi, my sister found an original SE/30 in some hidden cupboard (from her late husband). How much is such a thing worth??

Hello, that's worth minimum 100€ , but how is the condition of computer and case ?
Is it 100% functional (with macOS) and are there additional functional parts like Keyboard and Mouse ?

-> auf ebay.de wird sowas in gutem Zustand für 500€ und mehr an Sammler angeboten !
😉 (ob das einer kauft, kann ich nicht sagen) 🤣


Perhaps the easiest way : check out ebay (condition of computer & case, functional, additional peripherie) ?

I pay for some old defected Macintosh cases 50€ (without technic and frame) to 75€ (+ defected inside parts)
-> but a conversion is worth it only if you get a cheap HDMI 8" screen (AliExpress or Amazon importer)
-> Given the screen size, it’s usually not worth it — unless you’re drawn to the Macintosh’s iconic design
or have a passion for collecting — on the other way, you could always sleep under a bridge (it’s cheaper, too) !

😉 ...so, it's your choice !

hello!i try many amd and bootcamp and others drivers but i give up…AMD FirePro S7100 and no sound under windows11,on mac oses-try high sierra,oclp monterey and ventura always freeze on streaming like a prime video or netflix.Somebody have a experience with this GPU?buy on ebay with pre flashed vbios but i try different bios and always same thing
 
I'm having a problem with my iMac 11.3 with an Nvidia K3100M card.
I bought it through Aliexpress, and the card has the Nikey22 software installed.

Everything works fine: brightness adjustment, boot screen, and Metal support.

On every system, without exception, the card has poor performance; windows freeze, and animations are very slow. The system is sluggish.

The dock and top bar transparency work. What could be the problem?
 
All settings are standard from app for host model, exepct NVIDIA GOP, and force Kepler driver
OCLP, yes? And you are positive you have the correct settings for EFI and have post-install patches installed correctly?
Settings are predefinied for host model, excepct overwrite NVIDIA Kepler and NVIDIA GOP injection.

Post install corectlly installed.

I am afraid your card is the problem. I had the same problem with an AMD m6100 card, it worked but very unreliably. I bought another M6100 and flashed exactly the same vBIOS and it worked flawlessly.
 
For all who want to install Parallels and Win11 on an upgraded 11,3 iMac:

I upgraded this 11,3 iMac with an AMD M6100 card and installed Sequoia and 8GB RAM. All went well but when I installed Parallels and Win11 a strange problem occurred: whenever I started Win11 the sound would disappear on both sides (Win + MacOS). When I stopped Win11 the sound came back on MacOS. I spent hours on the internet to understand the problem. In the end the fix was easy: more RAM! With 12GB the sound was ok on both sides.

Strange thing: I also upgraded an 12,2 iMac with an ADM WX4130 card and 8GB RAM. With this configuration I had no problem with Parallels and WIN11.
I guess it has something to do with the type of graphic card.

Hope this helps.

Use default drivers in Windows, not Realtek and you'll have sound on both.
 
There is a possibility to check version Nikey BIOS on my card? Maybe too old bios version is a problem. If any hope, ill install Windows and try to reflash.
 
Hi
i am having a huge Problem right now.
On the 2011 iMac 27" i had a gpu failure, so i followed this guide and bought a k1100m.
When i am booting the computer now on this Thumb drive linux to flash the gpu the Computer does not boot properly and is not visible in my Network even though plugged in into Lan.
The display stays black as it should. But the Computer also does not appear on my Network.
Too find out what the problem is i installed the old AMD gpu again and booted this one into the usb stick.
But again with this GPU the display stays black too, even though the GPU was working halfway before i swapped it.
But with the original AMD the iMac is visible in my Network and i can also ssh root it. But it says "cd /lib/live/mount/medium/flash" does not exist.
So i swapped again the K11000m in but it still does not work and i cannot flash the card via ssh root.
I really dont know what to do anymore, i have already spent three or four days searching fo rthe problem trying to get this thing to work, and have also tried this whole process multiple times. But it doesnt work.
Please help me.
Best regards

Are you sure to have a working K1100m video card and have you ever seen it running in another system?
 
Hello. I got a iMac late 2009 A1311 with a core 2 duo. Trying to upgrade gpu to a quadro K2000, but trying to flash with ch341a shows "Buffer size not equal to IC size". Trying to flash K2000.bin from Quadro_beta1.2. I wiped out the original vbios without backing up. Took the card from a dell precision that had faulty keyboard, display and also terrible condition. However ran benchmarks and the gpu seemed to work fine.

Well, the A1311 has the internal display connected via LVDS unlike later models (including the late 2009 Core-i models), which have it connected via eDP - so, you'd need a VBIOS which supports that. There are some AMD GPU based cards which are known to support LVDS and where VBIOS versions for the A1311 have been created, but I have not heard of any Nvidia based cards yet.
 
Hi guyz.

SO i've been using my 2011 27" imac with the K4100M. Windows 10.

I just changed the CPU from 2700k to the 2600 thinking it would solve the sleep and boot issues I have. Essentially what would happen with the 2700k was I would boot the system to a black screen and would need to try 10 ish times and one of those times it would finally show something on the screen and let me use the computer. I couldn't sleep the system though and had to just run it 100% of the time. I don't think I used OCLP to boot -- it was just a UEFI install of windows on the SSD that would boot. I don't have any mac OSX installed on the drive at all. The original HDD is still in the system but I think it failed so it's disabled.

Now, I put in a 2600 thinking this would let me boot like normal and sleep the system. This time I tried OCLP thinking I would need that. I'm not sure I have a working OCLP USB but it does show up in the boot picker when I hold ALT when starting. This is how I boot: I hold alt, choose OCLP and then windows to boot. I see the windows logo and the spiner, and it just turns to a black screen. Safe mode works.

So what can I do to make this system boot nomrally? Do I need to make a new OCLP USB? The OCLP that I boot with was made with my 21.5 imac which does have a version of OSX installed. I just recently made a new OCLP for the 27 where I chose the different mac type and I chose Nvidia GPU but I'm not sure of the other settings that are required.

I've also tried a bunch of troubleshooting with chatGPT and command prompts that had to do with rebuilding the boot files a bunch of times and setting it up to boot with the onboard graphics before the nVidia drivers load but none of that has worked yet.

Should I do something else with OCLP? I'm not using a huge USB stick because I don't actually want OSX on this computer.. I just need the boot loader to work and windows to boot. Please direct me to exact links of what I need to do because the documentation is too wordy, I don't know enough for anything to make sense to me when I'm reading these things on page 1 and also they don't really apply to me because I don't want anything with OSX to be installed on this 27" imac.

LLM AI (Large Language Model - offline AI) and Metal Video Cards (patched)

has anyone tried already LM Studio with Google Gemma 4 E4B (64Bit) with
patched Metal capable CPU, got 1st experience with CPU load vs GPU load ?

How many Output tokens did you got from your patched Metal GPU ?

I want to try in short time with :apple: A1312 (16GB) up from macOS Big Sur
(if it runs, configuration follows)...

I like to visualize my thoughts and help this community to give these old machines a task they can manage,
with patched Metal capable video cards - you can't expect me to raise questions and concerns here that
1.000 people 🤪 have already asked before
🚮 without researching first the topic of BIOS updates for specific

graphics cards on the famous Page #1 of this thread.

What is the worst-case of running offline AI on an iMac A1311 or A1312 ?

-> That the CPU manage all AI instructions (and the patched "Metal 1" capable video card was not supported)
-> that only NVIDIA or AMD Radeon Pro (WX series or S7100) can handle AI calculation on the 2009-2011 iMac.
-> what about Linux or WIN11 on an intel platform ? 😉 Edge AI performance & LLM support - haha !
-> manage that with Google Coral AI accelerator (Edge TPU) ?


So try it out 🫵 I know that these 🧑‍💻 people here (+ BIOS-Patcher 👩‍🎓 OCLP Community)
are the - Tip of the 🏔️ iceberg for :apple: Apple developers and can open the 🌈 gate !

Hi, I need help with some issues on the iMac 27 Mid 2011 and it's only on Windows 10. My i7 2600 processor runs at 1600mhz and does not rise above under any load. Also, I don't have a brightness adjustment, k3100m graphics card, but I don't know which bios it is with, but I can go to the boot menu and it displays it. tell me how to solve these problems.
 
Hello everyone,

I’m working on a GPU upgrade for my iMac 2010 27" (i5-760, originally with HD 5670). I am trying to install a Dell AMD FirePro W5170M, but I’ve run into a persistent issue where the internal LCD remains black, regardless of which vBIOS (from GitHub) I flash.

Here is a detailed breakdown of my situation:

1. The "Pre-boot" attempt on High Sierra (10.13):I used my original HD 5670 to set up OpenCore (OCLP 2.4.1, with GOP and GCN options enabled). After booting successfully with the HD 5670, I swapped in the W5170M.

  • Result: The internal screen is still black.
  • Observations: I can get a signal via DisplayPort (DP) to an external monitor. However, the GPU information in "About This Mac" is blank. Interestingly, I can trigger the internal LCD to light up using Target Display Mode (TDM).
2. The Bootloader Issue:Even after reinstalling OpenCore while using the external monitor, the Boot Picker (Option key menu) remains black. When I blind-pick the OC partition, the system often fails to boot (confirmed via SSH and remote desktop).

3. The Big Sur Attempt:I tried another approach: Upgrading the system to macOS Big Sur using the HD 5670, applying the Post-Install Root Patches, and then swapping in the W5170M.

  • Result: The internal screen is still black.
  • System Info: It shows "W5170M 14MB". Running a kext check in Terminal shows "No Kext Loaded".
  • External Display: Unlike in High Sierra, I now get no signal via DP to the external monitor in Big Sur.
Hardware Notes:

  • I have removed the original HDD (and its thermal sensor), as well as the Optical Drive (and its sensor).
  • I have NOT removed the temp IC/sensor from the W5170M GPU PCB itself.

I will be greatful if anyone can help me.

Perhaps you should read more about SMBUS - Problems with this GPU- and CPU combination !
This card is by performance really no game-changer in an A1312 from 2010, perhaps try a W6170.

The AMD W5170 (Metal I support) is not very powerful and similar to AMD HD5670 acceleration 😀
and I cannot understand why users don't use a NVIDIA K1100, K2100 or K2000 instead...


SMB-Dat #pin 16.jpg

Disable SMBIOS resistance information (W6170 same-lane GPU/CPU - parallel resistance calculation = faulty 129° Celsius)

Attention:
Before
desoldering one or two jumpers try and make sure that they are connected to the MXM
Lane 32
(Use a resistance tester / voltmeter and make sure the pin #16 is connected to one of these jumpers) !

This is perhaps (!) the easy-to-use alternative (than you don't need to desoldering the jumpers,
if one of them have connection) - if you are desperate enough to disable the SMB-DAT pin #16 !

I think the PCB layout of the W5170 is similar to W6170, S7100 and other MXM (A/B) GCN 1-3 cards !

I have not try out this solution, 'cause I never had a W5170 (I must look in my home depot)
but I'd have to check my spare parts boxes to see if I have something like that lying around...


...which BIOS do you use on your card (GOP / EG2 / EG) ?
It can be helpful, if you look at the date a W5170 solution here was published, then look at the
used OCLP version, the OS and the BIOS version which are available to the date of publishing.

(That is sometimes the most important that people here have a look at the date-dependent current configuration) !!!
