I recently purchased a Mac Studio M1. Tore it apart to see if the SSD card was up gradable,NOT. The SSD AP0512R that is installed is married using firmware or controller chips that only deal with the present SSD that comes with. Why? Also, there is a SSD slot on the other side but no controller chips? Is Apple teasing us?
Parallels, 10.14
The slot on the other side will not work with a commercial SSD device. if you had bought a different model, it might have another Array plugged in that slot.
The controller for all Macs (2018 and later, with T2 chip) or Apple-silicon Macs, that feature built-in SSD devices have an Apple custom controller and a bare data Array. The array is linked to the controller through firmware and can not be replaced by the end users -- It contains a portion of the Secure Enclave and part of the recovery software. Removing it bricks your Mac.
These Macs were always sold as "not internally upgradeable once manufactured'. Apple has never represented otherwise.
i blive the mand controller is in the doc the M1 chip and apple dose limit it but according to let you can change the ssd when it eventually fails and just a quick note the laptop that im typing this on is a 2019 13 inc MacBook Pro and this is my aunt's laptop my laptop broke and I'm at there place this laptop had 2 logic board repayments one by the ssd nand failure shorting the nand to ground and one out of warranty by a hand failure causing the computer to try to startup but fail to even loading boot picker or internet recovery
SSD card upgrade for MAC Studio
