they offer free recycling of old hardware https://www.apple.com/shop/open/free_recycling when you buy new hw see also https://www.apple.com/me/recycling/

I hope they also plant one or two small trees somewhere! And promote the use of refillable water botles on campus!!

Not sure if you're kidding, but around 2014 on campus we all got reusable water bottles, and I still of course have mine, as they're useful (and less wasteful).

Yeah, that's my biggest complaint with iMacs: I want to be 100% certain I can repurpose them as monitors later in their lives. I have a ten year old iMac at the moment that would make an amazing second monitor... but it doesn't quite have the features I need to use it like that. An HDMI input would be great.

> An HDMI input would be great. There is a reason that is difficult to do: the licensing terms for HDMI require manufacturers to put DRM in place to make it impossible (or at least not straightforward) to record from an HDMI source. It's nearly impossible to meet that requirement on a computer.

You're thinking of HDCP, not HDMI. HDMI recorders exist (Elgato built an entire brand off selling them for console game streaming) but they are not allowed to speak HDCP because gestures vaguely at DMCA 1201.

In the specific case of the iMac:

- USB-C video outputs are all either DisplayPort[0]. HDMI Forum was promoting an HDMI USB-C altmode but it was never implemented. USB-C HDMI adapters are all DisplayPort adapters that additionally tunnel DVI traffic (because HDMI 1.x is actually single-link DVI with a funny connector and extra bits).

- Apple used to support Target Display Mode for video input until the Retina iMac a decade ago. They dropped Target Display Mode because their 5K display panels were using eight lanes of DisplayPort, a configuration that doesn't exist[1] outside of Apple's custom display controllers. Every other 5K display (and even some 4K ones) were instead using multiple cables, with some extra (poorly-supported) metadata to tell the graphics card to treat both halves of the display as one.

Why Apple hasn't brought TDM back now that we have enough bandwidth for 4.5K over standard cables is beyond me.

[0] Or MyDP, aka "the funny Nintendo Switch altmode"

[1] Think of it like a "32-lane PCIe port". It's technically possible but no host or device silicon supports a link that wide.

Since this thread seems to be about niche asks for pro users, despite the product being targeted towards casual users who want an easy out of the box experience, I'll add my own to the mix. I'd love a bigger/better screen on these, specifically an ultrawide variety. An iMac Pro with an 8k ultrawide would be a near-instant purchase for me. I find the ultrawide form factor so good for productivity. I love the apple "it…

Using a large 8K display for productivity is underrated. I wrote a blog post about my experience: https://daniel.lawrence.lu/blog/y2023m12d15/

I have a Sony 43" 4K and would love a 55" 8K. I think that would be the perfect. I'm really disappointed there's no current option. I'm waiting. Everyone says 8K isn't worth it for movies especially at 55", but I don't want it for movies! It would make my computer "desktop" as big as my physical desktop. I seriously considered the QN700B. I wasn't sure if it would do 60Hz 4:4:4 and wasn't quite ready to buy a new Mac (my current Mac can't do 8K).

The displays on these iMacs are so crisp, but disappointing that 24" only. Happy that the base RAM is increased, perhaps trying to pander to AI audience. But, who buys these at costs almost at Macbook Pros? Isn't this just a monitor?

Or buy a real computer, plug in an Nvidia GPU, and save your DRAM for compute while using your VRAM for inference.

16 GB or 24 GB for inference doesn’t cut it for large models… Mac hardware offers up to 128 GB shared RAM.

It is in a weird middle ground. It is much worse ram and much slower hardware (factor 4 or so IIRC) and only an option if you need more than 24 but less than 200. Also, only if you think that 9000€ is pocket change but 20000€ is cost prohibitive. Also, you need all that power but no server, no ECC,... And you only ever want to do inference but no training or tuning.

If you want a Mac anyway, sure. But if you don't care, this seems like a very, very specific Venn diagram.

The people who like the magic mouse (not me) don't care, and the people who even otherwise would never use a magic mouse get to keep making fun of it. Why would they bother?

I like the magic mouse, and I care that I can't charge it while using it. I also care that I have to activate bluetooth in order to use it, even if it's plugged in. Same with the keyboard. WTFF.

Are you sure about the keyboard? Mine disconnects from BT when it's plugged in (and continues to work)

I hope more companies start recycling their own products. It makes me sad to see so much valuable electronics, so many "totalled" cars just thrown away on the same heap as other rubbish (and old cars respectively). Such a waste of resources is surpassed only by war.

Recycling electronics basically means crushing them and extracting some of the minerals inside. A lot of them can't really be recovered, and of course all the electricity that was used to create it is still gone and the water used is still tainted.

If you make electronics you should be forced to do everything humanly possible to extend its useful life.

Reading this on 2017 iMac 27" - is the first 5k iMac that couldn't be used as a monitor after the computer inside is irrelevant. I hope EU will push for some law that requires all AIO computers to work in monitor-only mode if internal hardware is no longer good enough or no longer supported by software updates. I love the 5k screen on this iMac but the CPU is too old for photo or video editing as software got so much…

> Apple is only "green" in their presentations - in reality they care more about inifite sales only. needs citation. I say this as someone who worked several years in engineering at Apple, and they were extremely environmentally conscientious years before it was a thing.

I send all my old stuff for recycling now and get a gift card in return. They just did this for my ancient iPad that won’t even run the latest iPadOS.

I go on a site, pop in the serial number, and they ship me a box for free with a return label.

I basically got $45 for an incredibly slow brick, so I’d say that’s pretty good incentive for their recycling program.

Sure, you could install Linux and upcycle it, but how many people are actually going to do that? I think the recycling program is actually great for the 95%+ of people and how they use their devices.
