Overwrite
Overwrite is a macOS utility for sanitizing external drives, USB sticks, and SD cards. Its Mac App Store edition deletes files and overwrites free space through the file system. Overwrite Elite can instead overwrite every block the Mac can address on an external drive, using 1-, 3-, 7-, or 35-pass protocols. Completed wipes produce a locally signed Certificate of Data Erasure; Elite certificates can be checked with a free standalone verifier. Elite also offers optional read-back after a multi-pass Full Disk wipe and prints measured coverage on the certificate. The utility is designed for external and removable media and cannot erase the internal boot drive. Both editions have no accounts, analytics, or crash reporting; Elite makes three disclosed connections, while the App Store edition uses Apple’s StoreKit. The free Preview plan lets users explore drives and app screens but does not include secure wiping or certificates. Annual Pro costs $12.99 per year, Lifetime Pro costs $24.99 once, and Overwrite Elite costs $99 once.
