Folders
Peekdown runs in a secure macOS sandbox. To display images referenced in your markdown files, Peekdown needs permission to access the folders containing those images.
- Common folders — Toggle access to Desktop, Documents, and Downloads
- Add Folder… — Grant access to any folder on your Mac
- Remove — Revoke access to a previously granted folder
Once a folder is granted access, Peekdown remembers the permission across launches using security-scoped bookmarks. The preview reloads automatically when access is granted.
