Do Apple devices ship with a TPM chip? My Mac doesn't have a TPM chip, but does an iPhone have of a TPM chip or how do I determine if the iPhone has a TPM chip or not? On my Mac, I use this command to check if TPM chip is there or not: ioreg -x | grep TPM.


I'm assuming that your TPM reference stands for "Trusted Platform Module."

According to Wikipedia:

Due to legal restrictions TPMs may not be deployed in a number of countries. Possible reasons for these legal restrictions include the fact that state security services may not be able to access data or keys secured with a TPM.

  • China
  • Russia
  • Belarus
  • Kazakhstan

Since Apple sells iPhones in China (see this NY Times article), we can infer that the iPhone doesn't ship with TPM chips.

See https://www.apple.com/business/docs/iOS_Security_Guide.pdf especially the part about the 'Secure Enclave' coprocessor.

All the Apple S2, Apple A7, and later A-series seem to have such a co-processor.

As stated here it's essentially a TPM: https://news.ycombinator.com/item?id=10918999
Though I guess you could still argue that, especially when not knowing the exact architecture and inner workings of this chip.

I can't find any mention of a "... unique and secret RSA key burned in as it is produced ..." (Wikipedia, 2017) inside the enclave processor for example. But I guess you could do more research ;)

BTW: I'm not sure if (and how) the presence of the 'Secure Enclave' chip inside iPhones might be affected by the legal restrictions that country's have as @JW8 so clearly states in his answer.
