File Island 0.3.3 — unsigned early access
File Island 0.3.3 is a focused reliability update for the native conversion-result shelf introduced in 0.3.2.
What changed
- Dragging a converted result no longer triggers the Island's outer Finder input target.
- Output-folder access remains active after the first drag, so the second and later files can be dragged out normally.
- Image results are decoded into real content thumbnails with ImageIO before falling back to Quick Look.
- Newly published JPEG and PNG outputs no longer fall back to generic document icons because of a redundant file-visibility preflight.
- Regression coverage now protects internal-versus-external drag routing, sequential drag sessions, security-scoped output access, and image thumbnail decoding.
Install
Download FileIsland-0.3.3-unsigned.dmg and its checksum, verify it with shasum -a 256, open the DMG, and drag File Island to Applications.
File Island 0.3.3 requires macOS 15 or later. The App contains universal arm64/x86_64 binaries, FFmpeg, ffprobe, the AVFoundation media validator, and its preset catalog. Users do not need Homebrew, Python, Node.js, or a separate media runtime.
This early-access build has an ad-hoc code signature, not an Apple Developer ID signature, and it has not been notarized. macOS may require System Settings → Privacy & Security → Open Anyway after the first launch attempt. Do not disable Gatekeeper.
Existing boundaries
- Fast sharing split accepts audited H.264 MP4/MOV with optional AAC audio and requires at least one positive size or duration limit.
- MP3 remains input-only; output is M4A, WAV, FLAC, or AIFF.
- WebP remains image input-only; verified image outputs are JPEG and PNG.
- Precise re-encoded splitting and named platform rules are not included.
Legal and privacy
File Island original code and assets remain All Rights Reserved and source-available. Bundled FFmpeg 8.1.2 remains under LGPL-2.1-or-later with the corresponding source archive, license, notices, and build record included with the Release. All conversion and splitting stay on the Mac.
