That's why I cannot use M1 Macs for work. I must have Intel compatibility to run VMs at near native speed. Unfortunately, I will have to buy Intel laptop.

I wonder how they are able to load the kernel image at all. The tutorial should answer, but from the mention of pongoOS, I suspect they are exploiting some flaw in the secure boot process itself to load an arbitrary image and pass execution to it.

Reading through the commit for DART support, it looks like Apple did indeed design their own IOMMU core rather than using ARM's reference SMMU.

Apple opened up the tooling to load custom kernels on Apple Silicon.

When was that? Last I heard (end of November), they said you could boot any signed version of macOS, but that they would not support booting other operating systems directly on the hardware. They said everything had to run through the hypervisor framework.

I'm finding it extraordinary difficult to believe that Apple could replace the existing Xeon-based Mac Pro (or even iMac Pro) with comparable performance & expandability in only two years.  Low end, no problem at all.

So exactly what is apple doing? Tile and the article make several claims that Apple has systematically disabled tile products but never said how. 

We keep hearing about airtags but they’re still rumor-ware. Personally, I don’t think I’d use either AirTags or Tile, but I don’t think Apple should lock a competitor out, either. 

Certain APIs needed for Apps to communicate with the iPhone that are needlessly disabled without having an impact on privacy. Now, somehow it looks that Apple disables these APIs especially if Tile needs them, so that’s somewhat strange and worthy to be investigated. It would not serve the public discussion to list obscure function names and I don’t know these, but I have experienced myself what these changes cause and how companies depend on these APIs for their business to operate.
