Will this make Apple Silicon Macs a fully open platform?
No, Apple still controls the boot process and, for example, the firmware that runs on the Secure Enclave Processor. However, no modern device is “fully open” - no usable computer exists today with completely open software and hardware (as much as some companies want to market themselves as such). What ends up changing is where you draw the line between closed parts and open parts. The line on Apple Silicon Macs is when the alternate kernel image is booted, while SEP firmware remains closed - which is quite similar to the line on standard PCs, where the UEFI firmware boots the OS loader, while the ME/PSP firmware remains closed. In fact, mainstream x86 platforms are arguably more intrusive because the proprietary UEFI firmware is allowed to steal the main CPU from the OS at any time via SMM interrupts, which is not the case on Apple Silicon Macs. This has real performance/stability implications; it’s not just a philosophical issue.
And wouldn’t it be a lot cheaper to just build your own PC rather than pay the premium for the apple logo?
It’s not virtualization. It’s actually booted and runs on bare metal, same as the way Windows runs on a normal Windows computer: a proprietary closed UEFI firmware handles the boot process but boots an OS from the “hard drive” portion of non-volatile storage (usually an SSD on Windows machines). Whether you run Linux or Windows, that boot process starts the same.
Asahi Linux is configured so that Apple’s firmware loads a Linux bootloader instead of booting MacOS.

Apple’s base configurations are generally cheaper than similarly specced competitors, because their CPU/GPUs are so much cheaper than similar Intel/AMD/Nvidia chips. The expense comes from exorbitant prices for additional memory or storage, and the fact that they simply refuse to use cheaper display tech even in their cheapest laptops. The entry level laptop has a 13 inch 2560x1600 screen, which compares favorably to the highest end displays available on Thinkpads and Dells.
If you’re already going to buy a laptop with a high quality HiDPI display, and are looking for high performance from your CPU/GPU, it takes a decent amount of storage/memory for a Macbook to overtake a similarly specced competitor in price.

Except the boot process on a non apple PC is open software. You can create custom a bios revision. The firmware on an apple computer is not open source. AFAIK you cannot create a custom bios on an apple computer.

No idea what you mean by this. You cannot buy Apple’s hardware due the restrictions Apple places on any purchases. Any hardware you can buy from Apple has a premium.

I think you mean that Apple uses its own memory more effectively then a windows PC does. Yes it does, but memory is not that expensive to make. To increase the storage space from 256GB to 512 is £200. I can buy a 2TB drive for that. More importantly, it can be replaced when it wears out. Apple give you a replacement price that means you need a new computer.
Apple computers are designed to make repairs expensive. They may have pseudo adopted the right to repair, but let us see how that goes before believing the hype.
Except the boot process on a non apple PC is open software.
For the most part, it isn’t. The typical laptop you buy from the major manufacturers (Lenovo, HP, Dell) have closed-source firmware. They all end up supporting the open UEFI standard, but the implementation is usually closed source. Having the ability to flash new firmware that is mostly open source but with closed source binary blobs (like coreboot) or fully open source (like libreboot) gets closer to the hardware at startup, but still sits on proprietary implementations.
There’s some movement to open source more and more of this process, but it’s not quite there yet. AMD has the OpenSIL project and has publicly committed to open sourcing a functional firmware for those chips by 2026.
Asahi uses the open source m1n1 bootloader to load a U-boot to load desktop Linux bootloaders like GRUB (which generally expect UEFI compatibility), as described here:
The SecureROM inside the M1 SoC starts up on cold boot, and loads iBoot1 from NOR flash
iBoot1 reads the boot configuration in the internal SSD, validates the system boot policy, and chooses an “OS” to boot – for us, Asahi Linux / m1n1 will look like an OS partition to iBoot1.
iBoot2, which is the “OS loader” and needs to reside in the OS partition being booted to, loads firmware for internal devices, sets up the Apple Device Tree, and boots a Mach-O kernel (or in our case, m1n1).
m1n1 parses the ADT, sets up more devices and makes things Linux-like, sets up an FDT (Flattened Device Tree, the binary devicetree format), then boots U-Boot.
U-Boot, which will have drivers for the internal SSD, reads its configuration and the next stage, and provides UEFI services – including forwarding the devicetree from m1n1.
GRUB, booting as a standard UEFI application from a disk partition, works like GRUB on any PC. This is what allows distributions to manage kernels the way we are used to, with grub-mkconfig and /etc/default/grub and friends.
Finally, the Linux kernel is booted, with the devicetree that was passed all the way from m1n1 providing it with the information it needs to work.
If you compare the role of iBoot (proprietary Apple code) to the closed source firmware in the typical Dell/HP/Acer/Asus/Lenovo booting Linux, you’ll see that it’s basically just line drawing at a slightly later stage, where closed-source code hands off to open-source code. No matter how you slice it, it’s not virtualization, unless you want to take the position that most laptops can only run virtualized OSes.
I think you mean that Apple uses its own memory more effectively then a windows PC does.
No, I mean that when you spec out a base model Macbook Air at $1,199 and compare to similarly specced Windows laptops, whose CPUs/GPUs can deliver comparable performance on benchmarks, and a similar quality display built into the laptop, the Macbook Air is usually cheaper. The Windows laptops tend to become cheaper when you’re comparing Apple to non-Apple at higher memory and storage (roughly 16GB/1TB), but the base model Macbooks do compare favorably on price.
The typical laptop you buy from the major manufacturers (Lenovo, HP, Dell) have closed-source firmware.
FTFY: The typical laptop MOST buy from the major manufacturers (Lenovo, HP, Dell) have closed-source firmware. Though, I totally agree there are some PC suppliers with shitty practises. Where we disagree is that is if the firmware is fixed by the hardware manufacturer, then you have control over everything on the system. It is only when you have control of the base functionality of the system that you can say you are in charge. This may be too literal for you, but I just see that as a trust level you have in the manufacturer not to abuse that control.
17 inch screen (2560X1440) over the 15.3 inch (2880X1864)
16gb memory - 8GB upgrade to 16gb=+£200
1TB SSD over 256GB (upgrade to 1Tb=+£400)
8 full core/16t CPU (AMD5900hx) over an 8 core non hyperx cpu, 4 cores are cheaper variants.
All of the PC components can be upgraded at the cost of the part + labour. Everything on the Apple will cost the same price as a new computer to replace. Mainly because it is all soldered onto the board to make it harder to replace.
This is a £1400 laptop from scan V’s £1500 macbook air currently.
Ah, I see where some of the disconnect is. I’m comparing U.S. prices, where identical Apple hardware is significantly cheaper (that 15" Macbook Air starts at $1300 in the U.S., or £1058).
And I can’t help but notice you’ve chosen a laptop with a worse screen (larger panel with lower resolution). Like I said, once you actually start looking at High DPI screens on laptops you’ll find that Apple’s prices are actually pretty cheap. 15 inch laptops with at least 2600 pixels of horizontal resolution generally start at higher prices. It’s fair to say you don’t need that kind of screen resolution, but the price for a device with those specs is going to be higher.
The CPU benchmarks on that laptop’s CPU are also slightly behind the 15" Macbook Air, too, even held back by not having fans for managing thermals.
There’s a huge market for new computers that have lower prices and lower performance than Apple’s cheapest models. That doesn’t mean that Apple’s cheapest models are a bad price for what they are, as Dell and Lenovo have plenty of models that are roughly around Apple’s price range, unless and until you start adding memory and storage. Thus, the backwards engineered pricing formula is that it’s a pretty low price for the CPU/GPU, and a very high price for the Storage/Memory.
All of the PC components can be upgraded at the cost of the part + labour.
Well, that’s becoming less common. Lots of motherboards are now relying on soldered RAM, and a few have started relying on soldered SSDs, too.
True by the letter but not really by practice. PC is synonymous with a computer running Windows, or Linux at a push. I don’t know whether that’s because of Microsoft’s early market dominance or because Apple enjoys marketing itself as a totally different entity, or some combination of the two. But yeah, usage determines meaning more than what the individual words mean in a more literal sense.
Originally “PC” was IBMPC or PC Compatible (as in compatible with IBM without using their trademark). An IBMPC could have run DOS, Windows or even OS/2
I doubt it’s the last time.
also while “PC” means personal computer, it was a very specific brand name by IBM, not a general purpose term. their computers (and clones later) became synonymous with x86-windows machines.
Even apple themselves have always distanced themselves from the term (I’m a Mac, and I’m a PC…).

I agree with you, but you know how Apple operates, slapping a shiny new name on an already existing concept and making it sound premium.

Can you run that outside of a virtual box?

So you will still be at the behest of the AppleOS.

Apple leans heavily on the display being good on an Apple but imo it does not make up for the pricing. There is a good guide on better alternatives here.

I think the history is such that a “PC” is a computer compatible with the “IBM PC” which Macs were historically not and modern ones aren’t either.
But I still like “Windows computer”, we can abbreviate that to “WC”.
Another complication was that DOS-using machines weren’t always running Windows at one point in time.
