How to erase hard disk mac

Some people say that the standard erasing of an SSD makes data recovery hard enough for it to be "secure. Technology such as wear leveling , which tries to ensure each memory block on an SSD is used the same amount of times, can really mess with a secure erase.

Erase and leave no trace

That said, if you think you can do better than this , or if a professional service is not in your budget, or if you simply believe smashing it with a hammer is more satisfying, have at it! Just make sure you take the necessary safety precautions.
