Currently, the maximum storage available for the M4 Mac Mini through Apple’s official channels is 2TB. The 4TB and 8TB configurations are not available for the M4 Mac Mini, as they require different NAND chips, which are only found in the Mac mini M4 Pro variant. The M4 Pro has a completely different PCB and power management IC design.
Installing 4TB or 8TB NAND chips into the M4 Mac Mini would involve using non-Apple NAND chips and making significant modifications to the power management circuits. For now, we believe it’s best to avoid such modifications to ensure product safety and reliability. However, we may explore options for these higher capacities in the future, using thorough testing to meet our quality standards.
