iFixit publishes teardown of M1 iMac, but making a determination of repairability is still hard

As expected, it’s just as unservicable as all the other M1 Macs, with soldered storage (in this case, a 128GB Kioxia NAND module) and RAM located on the CPU package (namely two SK Hynix LPDDR4x modules).
Whereas the previous Intel iMacs allowed some degree of upgradability, the Apple Silicon variant ultimately does not. No surprises here. These are where the winds have shifted industry-wide.

At least disassembly is familiar, albeit not exactly straightforward. As was the case with previous iMacs, the avenue of ingress was through the screen.
Apple affixed the display directly to the protective glass cover, allowing iFixit to detatch the pair with one swift movement. With little adhesive used, it cut through the glue with a miniature pizza wheel without having to apply any heat first.

By contrast, Apple previously treated both components as discrete units, with some models notorious for the amounts of rock-hard adhesive used. Admittedly, this approach had its own advantages. If you damaged the glass, that was all you had to replace. On the flip side, it also made it easier to damage the delicate LCD panel lurking underneath.
From this, we can infer that the latest 24-inch iMac allows for easy display replacements. But The Reg wouldn't be too certain.

In recent years, Apple has shown an unsettling enthusiasm for component serialisation. This effectively means individual components are linked to the logic board, preventing third-party repair shops from using donor parts obtained from other faulty devices. The iPhone 12 is the best example of this.
If you switch a camera from one iPhone 12 to another, it [7]won't work properly . If you re-use a display panel, Apple will [8]disable TrueTone and warn the owner they're using a non-genuine part , as recently noted by Aussie right-to-repair advocate Hugh Jeffreys.

Until software workarounds are discovered, the only way around this is to seek repairs from the Genius Bar, or another Apple-certified technician.
And so, it's really hard to make a determination as to whether the inaugural Apple Silicon enjoys a modicum of repairability from a simple teardown alone.
iFixit is expected to continue with its teardown later today, with the sound system and Magic Keyboard due an investigation. The right-to-repair group will also issue a repairability score. ®

Re: Where are the old teardowns?
How much solder did they apply to the discrete components on the oats and where you encouraged to repair boards yourself from spare components from other boards?
Re: Where are the old teardowns?
Well, for the S100 systems I used in my first job, "yellow wire" repairs (bugfixes) were something the owners were encouraged to implement. These were usually a wire or two soldered in, or a resistor clipped or replaced. Once it was replacing a hex buffer chip with a faster one.
e-waste
The real thing people should be going after electronics like Macs is how recyclable they are. I don't necessarily mean component removal. If grinding the thing up and treating it as ore is an environmentally great way to recycle it, so be it. But most of this stuff just eventually ends up in a open dump fill in places like Ghana.
Re: e-waste
What most peeps don't know is that any electrical seller is obliged to take your e-waste and recycle accordingly. ANY e-waste. You could waltz up to PCCurriesWorld with a chest freezer and expect them to take it off your hands
Re: e-waste
I believe that in the UK the seller is legally allowed to refer you to a recycling plant rather than necessarily take the equipment back. So for anything involving refrigeration fluids, your local household waste management site should be the first port of call, although I'm not sure where I should take my now defunct Dyson vacuum cleaner, but there is an 'electronics' section at my local establishment.
Re: e-waste
You could try that but…
Here in the US, supermarkets have plastic-bag collection bins by the front door. (Not sure if they’re legally mandated or not).
Having watched them being emptied a few times, I’m pretty sure the bags go straight into the dumpster.
Re: e-waste
Sadly, for a variety of reasons [1]that's the case with a lot of US 'recycling' -- including curbside pickup in many areas.

Where are the old teardowns?
Maybe I should publish a teardown of some of my old IMSAI and Altair systems, easy to do - just pull the cover off and swap one, or occasionally two, of the S-100 boards if necessary to get them up and running again although occasionally adding an extra wire to the front panel helped.
