Apple Silicon Macs can't boot from external drive if internal drive failed
I get that the memory bandwidth and performance of the SoC is intimately tied to the CPU, GPU and memory being on the same silicon (grossly vulgarizing the approach).<p>However, there is no reasonable justification (as far as I can tell) for why the SSD would have to be soldered onto the same SoC, and even less reasonable justification for why the iBoot stuff couldn&#x27;t be located on an EEPROM or something of the sort, like a secondary BIOS&#x2F;UEFI.<p>It just boggles my mind why Apple would go so far to limit storage options and even make a straight up bad architectural decision (SSD gone ? You can&#x27;t boot the 4k€ machine. What ? You bought it 4 years ago ? Well, tough luck.)
