Modder dosdude1 changed an entry-level MacBook Neo’s common 256GB of soldered storage with a 1TB NAND flash chip from an iPhone 16 Professional. We’re all conscious that Apple by no means permits you to order a big capability on this particular laptop computer mannequin, although the machine and cellphone each use the identical A18 Professional processor. Nevertheless, as a result of they do, this swap is definitely potential with out the necessity for any particular adapters or fancy chassis redesigns.
To start, you will need to disassemble the machine, eradicating all connectors and lifting out the logic board. As soon as that’s executed, take off some shielding tape to realize entry to the storage compartment, which is a decent match. Earlier than you may change the outdated chip, soften the connections with a scorching air pistol and thoroughly take away the underfill glue little by little to forestall injuring any neighboring surface-mount parts. An IC spatula turns out to be useful for eradicating the outdated chip with out damaging something.
The brand new 1TB K8A5 NAND chip is a clean slate, thus it have to be re-balled with new solder spheres to exactly match the board footprint earlier than it may be put in. After that, a little bit of flux cleans the vacant pads on the logic board, adopted by one other spherical of precision heating to repair all the things in place and supply secure electrical bonding throughout the BGA array.
After reassembly, step one is to see if the laptop computer acknowledges the extra storage, which it does immediately, however you will have to carry out a full DFU restoration from a second Mac to deliver the system absolutely on-line. That second Mac will probably be your finest pal through the course of, and a few benchmarking reveals simply how large of a distinction 1TB of additional storage makes, since not solely does capability enhance, however learn and write speeds additionally enhance.
Wanting carefully on the cleared footprint of the outdated NAND chip does offer you a little bit of a touch that Apple did truly design the board with extra flexibility in thoughts, as there’s an entire ring of unused pads round the principle contact space, suggesting that they have been planning to supply totally different NAND packages even when they by no means truly ended up doing so, and the perfect half is you don’t want to fret about any software program patches or firmware hacks as a result of the processor already
