Perhaps the most critical Apple-specific thing to note about the TPM is that Apple's firmware is not TCG-aware in that there's no Apple-provided provision for asserting "physical presence." Some sensitive TPM operations (such as "clearing" the TPM, which results in a new TPM owner being established and any previous owner being forgotten) require physical human presence to be asserted. For example, to assert physical presence on some computers with TCG-aware firmware, one must press the Fn key at power-on time, enter the BIOS, and clear the TPM from within the BIOS. There is also a software-initiated way to assert physical presence, which is what we will use. The key thing to realize is that the software method is normally only possible when the firmware is TCG-unaware. If not, the firmware locks physical presence, disallowing the software method and resulting in stricter security. Do you know if this fix will work on a surface pro 3?

The industry standards from the Trusted Computing Group (TCG) specify that TPM manufacturers must implement some form of protection logic in TPM 1.2 and TPM 2.0 chips. TPM 1.2 devices implement different protection mechanisms and behavior. In general, the TPM chip takes exponentially longer to respond if incorrect authorization values are sent to the TPM. Some TPM chips may not store failed attempts over time. Other TPM chips may store every failed attempt indefinitely. Therefore, some users may experience increasingly longer delays when they mistype an authorization value that is sent to the TPM. This can prevent them from using the TPM for a period of time.
