`hdiutil makehybrid -hfs` gave every file in the image a com.apple.FinderInfo, which `codesign --verify --strict` rejects as "Finder information, or similar detritus" on the app in the DMG and on copies installed from it, so compliance and MDM checks reported the notarized app as damaged. As PdfCraft did (storytold/pdfcraft#823, shipped in PdfCraft 0.6.0), the DMG is now made with `hdiutil create -srcfolder -fs HFS+ -format UDZO`, retried when a CI runner's device is busy, and the app mounted from the finished DMG must pass `codesign --verify --strict --deep` before the release goes on.

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/vectorcraft-small.svg, linked, not copied) cropped as a cover on the VectorCraft colour field (#e8573f), Ink and Paper, Inter and JetBrains Mono (from assets/fonts, not embedded). |
background.tiff |
The background at 1x (660 × 400 px, 72 dpi) and 2x (1320 × 800 px, 144 dpi) in one HiDPI TIFF (Deflate, sRGB). Goes to .background/background.tiff. |
DS_Store |
Finder's view settings for the volume: window size, icon size 128, VectorCraft.app at (326, 205), Applications at (574, 205), and the background. Goes to .DS_Store. |
generate.py |
Writes background.tiff and DS_Store from the SVG and the layout above. |
Rules
- The volume name has no version (
VectorCraft, notVectorCraft <version>)..DS_Storepoints at the background through an alias that includes the volume name, so a versioned name loses the background. The DMG file name still carries the version. - 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, as packaging/icons.sh
It renders the SVG with resvg using only the fonts in assets/fonts, so the pixels are the same
on every machine, and writes DS_Store from scratch: the background alias holds the volume name
and /.background/background.tiff, nothing from the machine that ran it. The window is 660 × 432
with Finder's 32 pt title bar; the content area is 660 × 400.
