Note	Apple's announcement that Private Cloud Compute (PCC) extends to Google Cloud systems with NVIDIA GPUs, using NVIDIA Confidential Computing, Intel CPUs with TDX and Google's Titan chip. Apple says its software attestation is "rooted in at least two separate roots of trust from independent vendors" for components that could be abused to exfiltrate user data if compromised. It says attested keys are held in a separate confidential VM. It also says it will publish the binaries and provide access to live nodes in research mode through the Apple Security Bounty. Apple states that PCC on Google Cloud "will be gradually ramping towards the complete set of protections throughout the summer preview period". Supports only "Apple reports" statements.
