FlowClone 0.3.4
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:
- Open the
.dmgand drag FlowClone to Applications. - Remove the download quarantine flag — one line in Terminal:
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.
xattr -dr com.apple.quarantine /Applications/FlowClone.app - Open FlowClone (right-click → Open the first time if prompted).
- 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.
