Apple's 256GB SSD in the MacBook Neo can be swapped out for 1TB one with skill and with an iPhone component. You probably don't want to do it.

Apple never offers any official way to increase the storage in a Mac after you have bought it. But in the last few years it has become more relaxed about making it possible to do, usually now by slotting a larger-capacity drive into Apple's connectors.

There is no way to do that with the new MacBook Neo, but YouTuber dosdude1 has upgrade the storage with the kind of NAND chip used in the iPhone 16 Pro. It can't actually be taken from an iPhone 16 Pro you happen to have lying around, though.

"If I were to transfer one from an iPhone 16 Pro specifically that's been used already, it probably would not work on this machine," notes the YouTuber. "The NANDs do need to be blank, unprogrammed, to work on new hardware."

He doesn't say where he sourced this NAND, but does describe the chips as being readily available. He implies that the cost was around $200.

That is more than the $100 that Apple charges to sell a MacBook Neo with more storage, but it only gets you 512GB. Apple does not offer a 1TB option at all.

This does make the upgrade tempting, but it requires a user to start by disassembling the MacBook Neo. There's work to do preparing the NAND, which the YouTuber does on a separate Windows PC.

Then there quite delicate soldering to get it into place.

YouTuber dosdude1 notes that the same process cannot be done to upgrade the amount of RAM in the MacBook Neo.

"That's not upgradeable because of the design of this particular SOC [system on a chip] RAM package," said dosdude1. The RAM is too integrated into the system to be swapped out as the storage can be, with patience, time, skill, and money.
