"Mac doesn't start after installing SSD"に関する回答The issue you describe sounds like a P.O.S.T. failure. When you first start a computer whether it's a smartphone or a super computer and everything in between runs a Power On Self Test. This is the first program that every computer runs before the operating system is loaded. If there is a failure the computer will not boot. The P.O.S.T. is controlled by the BIOS.
