With the exception of Mac Studio and Mac Pro, recent Mac models don't have any replaceable components. The working memory is located directly in the system circuit and the storage circuits are soldered to the motherboard. Therefore, customers have to choose the right device from the beginning, and many later discover that they have chosen too little memory or storage space.
It doesn't have to be that way with storage, which is obvious since the Mac Studio and Mac Pro have replaceable SSDs. Hardware hackers have previously shown that it is also possible in some cases to change the NAND circuitry, for those using a soldering iron.
In a new one video The Iboff RCC Youtube channel shows that it's possible to give other Mac models similar removable storage to Mac Studio. The channel first removed the soldered NAND circuits from a Macbook with the M1 system circuit. Next, the modders produced a thin subcard that had an M.2-like connector soldered in the same place. A small circuit board with NAND circuits is then placed in this connector.
The circuit boards are designed so that the NAND circuits are electrically connected to the motherboard as if they were soldered into place, and the computer starts up fine and can even be reset after upgrading from 256GB to 2TB storage using another Mac and Apple Configurator programming.
In addition to the ability to upgrade the storage, replaceable SSDs make it easier to repair your computer if the storage unit fails or becomes damaged. New laws that impose greater requirements on the repairability of electronic devices have already forced Apple to make changes, and it's possible that the company will eventually move to something similar in more Mac models.
