@Dhanabhon Dhanabhon released this 29 Jun 17:07

FlowClone is a Tauri v2 desktop app for SSD migration on macOS — Image Migration (read a source SSD into a .flowimg) and Restore Image (write a .flowimg back onto a target SSD).

This release fixes a real blocker for Smart (used-only) imaging.

Download (macOS, Apple Silicon)

FlowClone_0.3.4_aarch64.dmg below — Apple Silicon (arm64) only. The app is unsigned (no Apple Developer ID / notarization), so macOS Gatekeeper blocks it on first launch. To install:

  1. Open the .dmg and drag FlowClone to Applications.
  2. Remove the download quarantine flag — one line in Terminal:
    xattr -dr com.apple.quarantine /Applications/FlowClone.app
    
    Without this, a browser-downloaded unsigned app shows "FlowClone.app is damaged and can't be opened" on Apple Silicon. It is not damaged — that's just Gatekeeper refusing an unsigned, quarantined app.
  3. Open FlowClone (right-click → Open the first time if prompted).
  4. Grant Full Disk Access: System Settings → Privacy & Security → Full Disk Access → enable FlowClone, then quit and reopen. Required to read/write raw disks and to read images from protected folders (Downloads, Desktop, Documents).

Intel Macs: build from source (pnpm install && pnpm sidecar && pnpm tauri build).

Fixed

  • Smart (used-only) images were wrongly blocked with "Not Enough Space" when
    the destination had less free space than the source disk's capacity. The
    free-space pre-check sized the requirement to the full disk (e.g. 512 GB) even
    for a used-only image that stores only the used data (e.g. ~52 GB). It now
    sizes the check to the disk's used bytes plus headroom (compression shrinks it
    further), so a ~52 GB Smart+Compress image no longer needs 512 GB free. Full
    images still require the full capacity. Fixed in both the GUI pre-check and the
    CLI.

Changed

  • The Direct Clone mode icon is now two stacked drives (a clearer
    disk-to-disk clone cue) instead of a small drive, arrow, and larger drive.
