I could not grasp the “why” here, not for the life of me. A Mac mini/studio would have been so much straightforward for the actual cited problem of “needing to develop on Apple hardware”.

I have to say I'm a bit perplexed as to why a person who is living in a small camping trailer would not want a normally functioning laptop with a screen.
I could see something like a macbook laptop sans screen being useful if it was like, perma wired into the electronics enclosure in a cabinet on a boat and plugged into an existing monitor/keyboard/touchpad... Maybe a tiny two way HDMI KVM switch to toggle between it and an existing x86-64 small computer?
There's a lot of that with this guy... His comment about requiring a low power environment so he discards all laptop power bricks. Dude, unless you're powering things off a hand cranked dynamo a few laptops are not going to melt your fuse board.
My guess is that the "why" is largely just showing off, coupled with oddness.
I have an M1 14" macbook with a broken screen. Would have cost $600+ to get it replaced so i just bought another refurbished one for $750. If i want to use the keyboard its kind of annoying to have to deal with the useless screen, so I would be open to just taking the dang thing off.
>I tried Virtual Machines, probably had half a dozen MacOS VMs over the years in VirtualBox and QEMU/KVM. Getting MacOS working in a VM is difficult, inconsistent and (at least on my machines) performance isn’t great. Apple strongly does not want you doing this, you’ll always be swimming upstream.
Idk. A year or two ago I wanted to test something on Mac. I searched a bit and found an image and probably copied a qemu config from somewhere, and it worked without any obvious problems. I'm sure there was a performance hit, but it wasn't unusable by any means, and I don't run the latest hardware.
I once bought an apple silicon macbook pro logic board to use with a kvm. It was a fun adventure. Things to notice:
-laptop lid closed/open sensor.
-no lid screen at first boot was a pain to fix to external monitor.
-logic board only on first boot requires macbook pro trackpad and keyboard(case), connecting external keyboard and mouse doesn't work at login screen due to security.
Once up and running though it is an excellent, cheap compiling/local llm machine i use over ssh from another mac
I just had this nightmare yesterday. Water damaged MBP so just the power button worked.
You can use any keyboard during recovery mode. But not connect BT devices (technically possible via some secret screen but it was stuck on a loading loop and needed a restart every time I tried) and I didn't have a wired mouse lol. So I had to voice mode + keybindings through a reinstall of MacOS which sounds easy but there were like 5 issues with focusing screens so regular tab didn't work and needed like cmd shift f4 and other mega random key bindings (thanks to AI this was easy to figure out though with enough trial and error). Had to restart it after an install thinking the keyboard would still work, but nope after login screen it wouldn't let me lol.
Pro tip — a magic keyboard with usb-c to lightning cable DOES NOT count as an accessory somehow. So you can use that.
There’s good crazy and there’s bad crazy. There’s good thinking different and there’s bad thinking different. This guy falls squarely on the latter of both.
> The battery bank from which I power my home is 12V (24V or 48V would be better and I’ll upgrade when the time is right). All my electricity comes from this battery bank.
> I have a power inverter, meaning I can use appliances with normal/household plugs, but the inverter wastes some power in the conversion process, stepping up from 12V to 220V. To then plug in a power brick, which will again throw away some power in converting 220V back down to whatever voltage a device uses, means double wastage, and a mess of plugs and wires.
Is this... a joke? How much freaking amps are you pulling? Average Canadian electricity consumption is 1270 watts. 1270 / 12 = 100+ Amps for one hour.
I'm guessing this is more of a third world situation and that electricity usage is much lower, but still...I fail to see how you would get to a setup like this. If you're fully off-grid then your generator or solar system could give you much higher voltage. If not, how are you charging the battery bank?
EDIT: From your CV, you are from the UK. I'm very confused.
Not the poster, but I live off-grid on a boat in the UK and pretty much everything (including the laptop I'm commenting from) runs off 12V DC.
I have 800W of solar panels and a 3.5kWh LFP battery bank.
I use approximately 2kWh per day in summer, 1kWh in winter, 500Wh when it's cold enough that I can turn the fridge off.
In the summer I dump any excess to an immersion water heater.
At that level the self-consumption power of an inverter, about 5-10W, is significant so I avoid relying on it for anything powered all day (but it's useful for appliances, power tools and other intermittent items).
Using incredibly wasteful amounts of energy isn't necessary, people just do it.
It sounds crazy but pulling >100A from low voltage battery is kinda normal for a 6kw solar inverter (in 220-250V countries). It needs a pair of 50mm2 wires which is thick as a rope though.

EcoFlow power stations draw somewhere around 30w with the inverter switched on with no load.
The idle power of a Mac Mini at the wall is a few watts total.
The relative tradeoffs (hacking together monitors, sketchy battery power, etc) don't seem to coherently add up to the stated goals.
Interesting read tho.
Here’s an M1 and somewhere in this guys Insta are photos of an M2 which is even easier as the cable is easier
