Regarding Apple’s walled garden in macOS, I think this explanation from Asahi Linux sums the situation up to a good extent: > The line on Apple Silicon Macs is when the alternate kernel image is booted, while SEP firmware remains closed - which is quite similar to the line on standard PCs, where the UEFI firmware boots the OS loader, while the ME/PSP firmware remains closed. In fact, mainstream x86 platforms are arguably more intrusive because the proprietary UEFI firmware is allowed to steal the main CPU from the OS at any time via SMM interrupts, which is not the case on Apple Silicon Macs. https://asahilinux.org/about/ https://asahilinux.org/about/
