Yes, files deleted from a storage media such as Mac hard drives can be retrieved, thanks to Mac data recovery software - which is supposed to do good things and recover files deleted accidentally, rather than to serve as an “evil” mean to restore data from someone else’s computer. Because the last thing you’d like to see is that someone “hacks” your Mac and retrieves the private/sensitive data. The point is: you probably want to know how to permanently delete files on Mac. Maybe you want to resell or donate your Mac, but paranoid about the security of your sensitive data? Or you are concerned about your Mac being stolen and the data could be hijacked?
You probably have heard about the famous iCloud leaks of celebrity photos, right? And you know the significance of digital data.
