Dragging files to the Trash doesn’t destroy them — anyone with free recovery software can bring them back. Overwrite Elite unmounts your external drive and overwrites every block the Mac can address — the whole device, not just the free space — then signs a record of exactly what it wrote.
No account · Zero telemetry · One-time licence · Apple silicon and Intel
This is an illustration of what a recovery tool finds after each method. Pick one and look.
Emptying the Trash only deletes the reference to your files. Every photo, tax return, and document stays physically on the drive until something happens to write over it — which can take years.
This is Overwrite Elite’s Full Disk workflow, rebuilt in your browser. Pick a protocol, slide, and watch the sector counter climb across every block the Mac can address — then read the signed certificate.
Serious data destruction in an interface anyone can use — and a record an expert can check.
Every completed wipe writes a two-page Certificate of Data Erasure: the human-readable record, and a machine-readable seal signed on your Mac with an ECDSA P-256 key. Hand it to a buyer, an employer or an auditor — they can check it with the free verifier, no licence and no network needed.
Overwrite Elite has no analytics, no crash reporting and no account. It makes exactly three disclosed connections — an update check, licence activation, and (only while certificate sealing is on) a 32-byte hash to a public timestamp server — and none of them carries your files, drives or wipe logs.
The privileged helper that opens a drive refuses anything attached to an internal bus and the disk your Mac runs from — decided underneath the interface, not by a checkbox. External and removable media only, in every mode.
In Full Disk mode, Elite force-unmounts the drive before the first byte is written, overwrites the whole addressable device through the raw block device, and rebuilds it to the format and name you chose — so it comes back ready to use.
On a multi-pass Full Disk wipe, Elite can read the drive back after the last pass — a deterministic 1% or 10% spot-check, or every block — and prints the measured coverage on the certificate. It is off by default, and a single-pass zero fill is never reported as verified, because a read-back of zeros cannot tell an overwritten block from a trimmed one.
Page two of every certificate carries the signed manifest, the ECDSA P-256 signature, the public key and its fingerprint, and a SHA-256 of page one. The key is generated on your Mac and kept in the Secure Enclave where the Mac has one. Change one value and the seal fails.
overwrite-verify is a free command-line tool for macOS 14 or later. It takes the certificate PDF, needs no licence and no network, and answers one question: has this record been altered since it was signed? A recipient without it can check the seal with standard OpenSSL tooling.
Examiners, IT asset disposal, and anyone who has to prove a wipe run Overwrite Elite: whole-device overwrite, read-back verification, and a certificate anyone can check. Everyone else can wipe an external drive from the Mac App Store. Labs and organizations license Elite site-wide.
