* Issue #390: build the DMG with hdiutil create so the app passes codesign --strict makehybrid -hfs wrote a com.apple.FinderInfo (Finder location -1,-1) on every file in the image, and codesign --verify --deep --strict rejects that as "Finder information, or similar detritus", on the app in the DMG and on a copy installed from it. hdiutil create -srcfolder writes the files as they are; it attaches a device while copying, so it gets up to five tries. A gate mounts the finished image read-only and verifies the app inside with --strict.

The same five tries with growing pauses now cover create, attach and detach.

macOS DMG window
What Finder shows when the DMG opens: a 660 × 400 pt background with the app icon and the
Applications link side by side. package.sh copies these files into the image; nothing here is
generated at build time, so the DMG builds with a plain hdiutil create -srcfolder (no Finder
scripting on CI, nothing extra installed in the signing job).
| File | What |
|---|---|
background.svg |
Source of the background: the app icon (assets/app-icon/pdfcraft.svg, linked, not copied) cropped as a cover on the PdfCraft colour field (#12a58a), Ink and Paper. Its text (Inter, JetBrains Mono) is outlined, so rendering it needs no fonts. No paper grain: noise doesn't compress, and this keeps background.tiff small. |
background.tiff |
The background at 1x (660 × 400 px, 72 dpi) and 2x (1320 × 800 px, 144 dpi) in one HiDPI TIFF (16-colour palette, Deflate, sRGB). Goes to .background/background.tiff. |
dmg-layout.DS_Store |
Finder's view settings for the volume: window size, icon size 128, PdfCraft.app at (326, 205), Applications at (574, 205), and the background. Goes to .DS_Store in the image; named so it isn't mistaken for (or ignored like) a Finder-generated .DS_Store. |
generate.py |
Writes background.tiff and dmg-layout.DS_Store from the SVG and the layout above. |
The volume name has no version
The mounted volume is called PdfCraft, not PdfCraft <version>. The layout points at the background
through an alias that includes the volume name, and Finder resolves it by that name: with a
versioned name the window keeps its size and icon positions but shows no background (tested).
The DMG file name (pdfcraft-<version>-macos-<arch>.dmg) still carries the version.
Rules
- Finder draws the icon labels in black in light and dark mode when a window has a background, so the area under both icons stays light (Paper).
- Nothing goes inside the icon boxes: artwork keeps 10 pt clear of each 128 pt icon box and of the label strip under it.
Regenerate
Edit background.svg (or the layout constants in generate.py), then run, on any OS:
pip install 'pillow>=12' ds_store==1.3.3 mac_alias==2.2.3
python3 packaging/macos/dmg/generate.py # needs resvg on PATH
Both outputs are byte-for-byte reproducible and carry nothing from the machine that ran it: the
SVG renders without any fonts, and dmg-layout.DS_Store is written from scratch, its background
alias holding only the volume name and /.background/background.tiff. If you add text to the SVG,
outline it (usvg from resvg converts text to paths). The window is 660 × 432 with Finder's 32 pt
title bar; the content area is 660 × 400.
