WWDC this year again featured a session on notarization. Here’s a summary of its status in Big Sur, and details of what’s next.

What would happen to a Mac’s firmware if you installed Monterey beta to its internal or external disk? Could that be reversed?
Recovery on an M1 Mac runs from its own container, which should improve its robustness. It has one simple entry point, and offers a full range of facilities in an integrated environment. It’s a big step forward.
What you can learn about the processes running on your Mac, its processor cores, even the files which an app has open.
By segregating macOS background tasks on Efficiency cores, M1 Macs can run user apps unfettered on their Performance cores. And that feels really fast.
How the M1’s asymmetric cores can run background tasks more efficiently, or deliver high performance, according to Quality of Service.
M1 Macs may be as fast as greased lightning, but how good is their numerical accuracy? Can it match that of Intel processors?
The last five years have seen great changes in Mac firmware security. As Intel Macs are replaced by Apple Silicon models, firmware may at last be simpler and more secure at last.
Internally, it isn’t called Rosetta, but OAH. Although itself tiny, its demands on memory and CPU can be great. Details of how and what it does, and more.
Processors haven’t just increased in speed and packed more transistors into a smaller space. Features such as the Neural Engine in the M1 show Apple is moving in a different direction.
