PDFOutliner
PDFOutliner is a macOS utility designed to help users create and manage document outlines for PDF files. It allows users to add, edit, and organize bookmarks and outline hierarchies within PDFs, making long documents easier to navigate. The app is intended for people who work with multi-chapter or multi-section PDF documents and want to add structured navigation without using a full-featured PDF editor.
AI Recommendation
1 suggestionWe could not find current information about PDFOutliner's development status or whether a native Apple Silicon build exists. The bundle ID (me.onekerato.pdfoutliner) suggests this is an indie or small-team project. To determine your path forward, contact the developer directly to ask whether a native Apple Silicon build is available now or planned before macOS 28 ships in late 2027 — that deadline is when Apple removes Rosetta 2 entirely, and an Intel-only build will stop launching on that release. As you wait for clarification, consider whether a general-purpose PDF editor with outline support — such as Preview (built into macOS and runs natively), PDF Expert, or Coherence X — might meet your needs as a contingency. If PDFOutliner is abandoned and no native version materializes, you will need to migrate your workflow to an alternative before late 2027.
