A1278 ssd upgrade3/23/2023 ![]() The interposer board ships with solder balls reballed onto it, so that it can be installed in the same way that a BGA chip would be – but the cable assembly connector isn’t installed onto the interposer, since it has to be soldered onto the mainboard with hot air, which would then melt the connector. The process is well-documented in the video, serving as an instruction manual for anyone attempting to install this specific mod, but also a collection of insights and ideas for anyone interested in imitating it. That adapter even lets you expose the PCIe link as a full-sized PCIe 4x slot, in case you want to connect an external GPU instead of the NVMe SSD! Apple laptops never came with proper M.2 ports, especially the A1278 – so what’s up? The trick is – desoldering a PCIe-connected Thunderbolt controller, then soldering a BGA-like interposer PCB in place of where the chip was, and pulling a cable assembly from there to the drive bay, where a custom adapter PCB awaits. ![]() ![]() Recently, we stumbled upon a video by, adding an M.2 NVMe port to a 2011-2013 MacBook. ![]()
