Using Secure Empty Trash (macOS x 10.10 and Below Only)
Know the difference between Trash and “Secure” Trash. Secure Empty Trash is a security measure designed by Apple to make sure sensitive files have their indexing removed from the hard drive and the space they occupied overwritten. Due to the way solid-state hard drives store data, this method is less reliable on solid-state drives. Therefore, this method is being phased out by Apple. The Secure Empty Trash option has been removed in OSX 10.11 (El Capitan) and higher.
