Originally the ‘security enclave’, and subject of a series of patents, it was introduced in the iPhone 5s in 2013, then the T2 in 2017, and blossomed in M-series Macs from 2020.
Explains the sequence of events from Boot ROM to FileVault login, what storage is accessible at different times, and where the code is.

How to check there’s no hardware problem, then use Restore in DFU mode to completely wipe internal storage, including firmware, and reset the NVRAM.
How to check your Mac is booting in Full Security, and how to read its log to verify all the key steps involved in that process.
Gives the latest firmware versions for all Macs running the most recent supported version of macOS, and which are expected to change in the future.

How your Mac can use less energy and power, run its battery down less, generate less heat, and keep its P cores for the work you want it to do for you.
Apple silicon Macs (and iPhones and iPads) with AI enabled load 23 cryptexes to support that. This explains how that works, and how you might see an odd volume named Creedence….
