The most recent Mac uses solid-state drives (SSDs), rather than traditional hard disk drives, and Apple’s Disk Utility program does not allow you to erase the hard drive in this scenario. Even a simple wipe may make Mac data recovery tough. Another concern is that erasing an SSD will harm your hard disk, which will eventually fail.
