It does, because it means I cannot just install Linux on the machine. I have to have macOS installed and running first, then and only then can I install Linux. It makes the hardware dependent on macOS, even if I just wanna run Linux.
Other computers you can have literally nothing on it, and then get Windows or Linux running on it (or macOS even).
I didn't make that list myself, it's from the official Asahi website. And I'm not gonna argue against you if each item on the list has a big impact or not. I'm generally a fan of Asahi (and I donate to their efforts each month), I was just putting it out there to show that there are actually a bunch of "drawbacks" (more like missing features) than people in this comment thread is letting on.
This is absolutely not the case, of course - it’s just the pre-installed environment you use to install Windows or Linux is called “BIOS” or “UEFI” instead of “macOS”.
- HDMI: the MacBook Air doesn't have HDMI, seems to work on the Mini or how are they getting a monitor attached. Or they use DisplayPort, what you listed as not working.
- GPU accelleration, I mentioned that. Of course you cannot expect Video accelleration without GPU support
- Neural engine: well, most other devices don't even have one.
- CPU idle certainly will come, run times are already excellent under Linux.
- Touch Bar: except for the M2 Pro, there are no devices with a touch bar left, and I expect the touch bar to go away entirely soon.
