Unfortunately, verifiable privacy is not physically possible on MacBooks of today. Don't let a nice presentation fool you.
Apple Silicon has a Secure Enclave, but not a public SGX/TDX/SEV-style enclave for arbitrary code, so these claims are about OS hardening, not verifiable confidential execution.
It would be nice if it were possible. There's a lot of cool innovations possible beyond privacy.
Every hardware key will be broken if there is enough incentive to do so. Their claims read like pure hubris.
As if you get privacy with the inference providers available today? I have more trust in a randomly selected machine on a decentralized network not being compromised than in a centralized provider like OpenAI pinky promising not to read your chats.
