* macOS: build the DMG with hdiutil create so the app passes codesign --strict hdiutil makehybrid -hfs put a com.apple.FinderInfo on every file in the image, so the signed app inside the DMG (and any ditto copy of it) failed codesign --verify --deep --strict. That is why verify.sh had dropped --strict. Build the image with hdiutil create -srcfolder (retried, since create can hit "Resource busy" on CI), clear build-time xattrs before signing, and make verify.sh check the app in the finished DMG and a ditto copy of it with --strict again. Ported from storytold/pdfcraft#823 and storytold/lightcraft#959. Co-Authored-By: Claude Opus 5.5 <[email protected]> * macOS DMG: branded window background and icon layout The launcher's DMG opened as a plain Finder window, unlike every other Craft app. Add packaging/macos/dmg/ the same way WordCraft and PhotoCraft did: a background (the ArtCraft mark whole on its blue, title, Ink and Paper), a .DS_Store with the window size and icon positions, and the generate.py that writes both reproducibly. The volume is now named "ArtCraft Launcher" without the version, which the background alias needs; the DMG file name keeps the version.

# 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, laid out like the other Craft apps' DMGs. `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 ArtCraft mark in black (`docs/brand/artcraft-mark-black.svg`, linked, not copied) whole on the mark's blue (`#4e7bfb`), Ink and Paper. The mark is a trademark: it stays exactly as supplied, never cropped or recoloured (`docs/brand/LICENSE-brand.txt`), unlike the cropped icons on the other apps' DMGs. Its text (Inter, Geist Mono from `assets/fonts`) 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, ArtCraft Launcher.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 `ArtCraft Launcher`, not `ArtCraft Launcher <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. The DMG file name (`artcraft-launcher-<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:
|
||
|
||
```sh
|
||
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 --skip-system-fonts --use-font-file assets/fonts/Inter-Variable.ttf
|
||
--use-font-file assets/fonts/GeistMono-Variable.ttf` converts text to paths). The window is
|
||
660 × 432 with Finder's 32 pt title bar; the content area is 660 × 400.
|
||
|
||
This follows the other Craft apps' `packaging/macos/dmg/` (storytold/wordcraft#21,
|
||
storytold/photocraft#1201, first in storytold/vectorcraft#493).
