Simply having a boot volume group with a System snapshot in it won’t get your Mac to start up from that disk, particularly if it’s an Apple silicon model. Some details.
Apple silicon
Secure Boot and its 5 stages, the SSV, support for external bootable disks, the SEP, Recovery, and lightweight virtualisation.
Memory, from L1 instruction cache to main memory, and how it came to be Unified. Why the internal SSD isn’t like others, and why it’s so essential.
How the NEON vector processor, neural engine, matrix co-processor, and GPU all deliver high performance with low power and energy use.
What do you do when your Mac refuses to log you in because it thinks your password is incorrect? Don’t rush or panic, but follow these steps.
Running threads at different frequencies on the same core type can’t save energy and extend battery endurance. That’s where 2 core types come in handy.
How power efficiency is just as important to desktop Macs as it is to notebooks, and the story of the Mac mini in power from 2005-2023.
A gentle introduction to the new architecture, from how macOS allocates threads to core types, overflow, variable frequency, ending in huge differences in power.
PC users will get 20 Gbit/s and SMART health indicators from this new external SSD, but Mac users will only see half that speed and no SMART without reducing security.
Virtualisation of macOS on Apple silicon does deliver performance that’s impressively close to that of the host. Here are the figures to demonstrate it.
