Get started · What DriveOff does · Use · Privacy · Requirements · For developers

Get started

1. Download the latest release and unzip it.
2. Move DriveOff.app to /Applications.
3. Open it and grant disk access if prompted.

What DriveOff does

• Plug in your drive, pick a folder, go.
• Filenames just work on your Mac.
• Your drive is never touched.
• Hidden system files are skipped.
• See what failed and retry.

Use

1. Select the USB drive.
2. Select a destination folder.
3. Click Import.

Failed files appear in the Errors section with paths and reasons.

Privacy and security

• DriveOff only reads from your drive.
• Files go straight to the destination you pick.
• Works offline.

Requirements

• macOS 11 or later.

For developers

Build, test, and publish

Requires Apple Command Line Tools with Swift 6 and Make.

xcode-select --install

make          # list commands
make run      # run the native SwiftUI app
make test     # run copy engine behavior checks
make check    # lint, test, and build
make build    # build the release executable
make package  # create build/DriveOff.app (ad-hoc signed, local use)
make distribute  # Developer-ID signing + notarize + staple (for releases)
make screenshot  # render docs/screenshot.png from the current UI

Publish a release with:

make release VERSION=1.0.0

This lints, tests, and builds locally, then tags and pushes v1.0.0 to trigger the GitHub Actions release workflow, which publishes DriveOff-1.0.0.zip and its SHA-256 to a new release. Or by hand:

git tag v1.0.0
git push origin v1.0.0

Unsigned builds work out of the box. To sign and notarize, add these repository secrets:

Secret	Purpose
DEVELOPER_ID_CERT_P12_B64	Developer ID Application certificate, base64-encoded .p12
DEVELOPER_ID_CERT_PASSWORD	Password for the .p12
APPLE_ID	Apple ID for notarization
APPLE_TEAM_ID	Apple Developer team ID
APPLE_APP_PASSWORD	App-specific password for notarytool

Without notarization secrets the app is signed but not notarized; without the certificate secrets it is unsigned. workflow_dispatch runs the same pipeline without publishing, so you can test a branch first.

Structure

• DriveOffApp — SwiftUI app.
• DriveOffCore — platform-independent filename and streamed-copy logic.
