PeekKit 1.3.1 (build 7) is a stable source release for Apple Silicon/macOS 14+.

Large PDFs

  • File-backed native PDFKit viewer replaces the 50 MB whole-Data preview gate.
  • Continuous scrolling, zoom, Previous/Next, page number + Go, page count and Fit.
  • No-follow descriptor pinning, local/cloud residency checks, asynchronous opening and explicit invalid/locked/unreadable errors. Archive PDFs keep the bounded in-memory path.
  • The private 86 MB/712-page PDF was verified locally in actual Finder folder browsing; no textbook content is included.

Safe 7z subset

  • Copy, LZMA1 and LZMA2, including bounded solid streams and compressed headers; integrated tree/list/search/navigation and text/image/PDF/Markdown previews.
  • Independent restricted header parser, 8 MiB dictionary cap, 16 MiB raw-decoder memory-estimate budget, 1 MiB header budget; existing 64 MiB input, 32 MiB file, 128 MiB decoded-total and 20,000-entry limits.
  • Encryption, filter chains/other codecs, unsafe paths/links, invalid metadata/checksums and resource-limit violations fail closed. No disk extraction or execution.

Verification and limits

218 checks passed from a clean clone, with host and both extensions built/signature-verified. Real Finder tests and genuine synthetic screenshots: validation.

ZIP Store/Deflate, TAR, TGZ/TAR.GZ and TBZ2/TAR.BZ2 remain supported. XZ, RAR, ZIP64, encrypted archives and recursive nested browsing remain unsupported. Native calls and the 10-second deadline are cooperative; codec-memory estimates are not process RSS ceilings. PDFKit image/page caches can use substantial RAM. Some keys are reserved by Finder; use PDF Go/visible controls. Complete VoiceOver, real cloud providers, other Macs/OS versions and prolonged stress are not claimed verified.

Build/install

git clone --branch v1.3.1 https://github.com/LujiaChen/PeekKit.git
cd PeekKit
./build.sh

Move .build/PeekKit.app to Applications, open it once, enable PeekKit Folder and PeekKit Markdown in Quick Look settings, and keep one registered installed copy. Preserve a temporary old copy until verified. Installation, PDF architecture, archive limits.

Attached source ZIP and SHA-256 manifest identify the tagged tree. No notarized binary is distributed; local builds are ad-hoc signed and require no paid Apple account or security bypass. Public-domain liblzma API headers are bundled with notices/provenance; runtime uses the OS library, with no 7-Zip CLI dependency.
