The T2 chip of the 2018 MacBook Pro with Touch Bar performs several tasks that are essential to the security of the computer and its proper functioning. Like its predecessor, this chip with a secure enclave is at the heart of the Touch Bar and Touch ID. And like on the iMac Pro, the T2 is super-controller of the system (it supports the audio controller and the SSD controller).
All this is good and good, but the immediately visible contribution of the T2 chip, apart from the rather anecdotic support of "Dis Siri", is the newfound vivacity of the Trousseaux d'accès utility. In particular, the search for an identifier or a secure note frequently (but not systematically, it is what makes the thing so painful) latency with MacBook Pro equipped with the T1 chip.
We were able to experience it on a MacBook Pro 15 '' with Touch Bar of the previous generation (2017) which, actually, is a little soft knee at this level. We have to wait a few moments before getting the result of the research …
This lag does not exist on our brand new MacBook Pro 13 inches, despite a database of identifiers and words pbadword well stocked. Admittedly, we are still lacking in perspective, but from what we have seen, there has been no slowdown to note. It is likely that this is the work of the chip T2, on which the good fairies of Cupertino have obviously bent.
