Mac mini (2024 model) with Apple M4 chip. This is a high-end configuration with 16GB of memory and a 2TB SSD, which costs 214,800 yen (tax included) on the Apple official website. The reason it's so cheap is simple: The power supply unit is damaged. Bringing it to Apple would cost about 30,000 yen, so I took it to a PC repair shop I know and had them install an external power switch (see photos). It starts up normally when you plug in the switch and press it, and macOS works without any problems. All ports, including USB/HDMI/LAN, are working fine, and the exterior is in very clean condition. You could either use it as is, or have it repaired by Apple for around 30,000 yen. Either way, it's a great deal. ■ Main Specifications ・Model: Mac mini (2024) ・Chip: Apple M4 ・Memory: 16GB ・Storage: 2TB SSD (Initialized, macOS 15.5 installed) ・Exterior: No scratches or dents, in excellent condition ・Modification: Modified to start with an external power switch (see photos) ■ Accessories ・Main unit ・Power cable ・External power switch ・Original box ■ Condition/Other ・macOS startup and operation confirmed ・All ports are working normally ・Very clean condition except for the power supply ・macOS will be re-initialized before shipping. ■ About the Transaction ・Negotiations for a slight discount are possible, so please comment if you have any requests. ・It is also listed elsewhere, so it may sell out depending on the timing.
