And for what it's worth, Macs have had this ability for basically as long as they've had Thunderbolt. The same can also be done over Firewire on all major platforms, but these days 400/800mbps just isn't what it was back in the day. edit: Also meant to mention that while Thunderbolt has always been rare on AMD due to its requirement of an Intel chip, USB4 is somewhat common nowadays as it's officially supported on the Zen 3+ and newer CPUs

yeah i had mac and had to clone disk over tb one time. but mac recovery is magical, wifi password is written in NVRAM and if you erased/replaced whole disk, "recovery agent" started and downloaded macos image over wifi and installed it ! it was on intel mac, im not sure if it still works same way in arm. it took 2 hours XD apples firewire and tb had problems with security, it was possible to do DMA reads from your ram over those. from external device.

  The DMA security issue was an Intel problem more than an Apple problem. It was Apple's popularization of Thunderbolt that got Intel to finally stop disabling IOMMU support for product segmentation reasons.

    security issue was Apple thing, they say security, privacy but have tb, firewire with posibility of "TSA" agents cloning your drive in 3 minutes. has nothing to do with any product segmentation. also they HAD icloud backups not encrypted, but had big public fight with FBI about unlocking ones iphone... good old days.

      > security issue was Apple thing Not true; basically everyone shipping laptops with Firewire ports in that era was at risk of DMA attacks. Apple was merely the most notable vendor trying to offer something better than USB 2.0. > has nothing to do with any product segmentation Go look at which Intel Sandy Bridge or Ivy Bridge processors had VT-d (IOMMU) capability enabled vs disabled. The product segmentation strategy is on plain display. They made overclocking mutually exclusive with IOMMU for several generations of processor. There's no technological basis for that, just artificial product segmentation. Please put at least a little bit of effort into fact-checking yourself before continuing ranting. It's not that hard, and you'll be much more convincing if you don't exaggerate your complaints to the point of being obviously wrong.
