What Happened to Secure Erase Free Space in macOS? Today we’ll discuss what happened to the Secure Erase Free Space feature in Disk Utility on your Mac and how to securely wipe the free space on your Mac’s HDD without that feature.

If your Mac has an SSD, you do not need to securely wipe the free space and you shouldn’t. If you have a regular spinning hard drive (HDD) in your Mac, you can securely wipe the free space on your Mac, preventing recovery of any files that were not securely deleted. If you didn’t already securely delete your files, it’s not too late.

However, anyone who gets a hold of your Mac, and who has intermediate computer skills, might be able to recover deleted files from your drive.
