Concerning that they're selling hackintoshes with AMD processors for commercial use.
I use an AMD processor and it's fantastic, but hackintoshing on AMD isn't a fun experience - a lot of apps don't work without modifications because they expect Intel-specific instructions to be present. No amount of OpenCore magic can fix that.
In my testing, Adobe software, Cubase and REAPER all crashed at launch. I'm sure other software is affected as well.
Parallels and VMware won't work because they expect to use the Apple virtualisation framework, which expects Intel VTx to exist (which of course it doesn't). The same is true for Docker.
Would add as well that, whilst I wasn't able to confirm this myself, I've heard reports of software having poor performance compared to what you'd get on an Intel hackintosh. Games run particularly poorly (much worse than they would on the equivalent Intel hackintosh).
AMD processors are fantastic, but they're a terrible choice for a hackintosh.
I would add as well that I'd be amazed if this website doesn't turn out to be an outright scam - no company information whatsoever, no indication of where they're based and only accepting bitcoin for payment is suspicious as hell. Honestly I'm amazed that MacRumors would stoop so low as to give them the publicity.
