About Overwrite
Overwrite is a disk-sanitization utility for macOS. It securely wipes USB drives, SD cards, and external storage so that “deleted” files can’t be brought back — overwriting the actual bytes with 1-, 3-, 7-, or 35-pass protocols aligned with NIST 800-88, then issuing a locally signed PDF certificate of erasure as proof. It’s made for anyone who sells, returns, or recycles a drive: dragging files to the Trash doesn’t destroy them, and free recovery software can bring them back.
Overwrite is built by ProfWorkBench, LLC and distributed exclusively through the Mac App Store. It runs 100% offline with zero telemetry — no accounts, no analytics, nothing ever leaves the Mac. For safety it deliberately cannot touch the internal boot drive; it works only on external and secondary media.
Approved boilerplate
Overwrite — secure disk sanitization for macOS. Deleted isn’t gone. Overwritten is.
Overwrite is a native macOS app that securely erases external drives, USB sticks, and SD cards beyond recovery. It overwrites the underlying data with 1- to 35-pass protocols aligned with NIST 800-88 and seals each wipe with a locally signed, ECDSA P-256 PDF certificate of erasure — all 100% offline, with zero telemetry. Available on the Mac App Store in 15 languages.
