Apple Places Encrypted Binaries in Mac OS X

BTW, an interesting fact has been pointed out by Amit Singh, author of a book describing Mac OS X internals: The first generation of x86-based Mac's - or at least some of them - contained a TPM chip (specifically, the Infineon SKB 9635 TT 1.2. However, Apple never used the chip - in fact, they didn't even provide a driver for it. It certainly was not used in generating the encrypted binaries. Proof? The most recent revision of the Macbook Pro does *not* contain a TPM chip. So in fact Apple is not using the TPM to "certify" a machine as being real Apple hardware. Presumably one can hack out the decryption key - it's in the software somewhere.... -- Jerry
