Rilmazafone — DMG Designer
Design & build disk images
Only for Mac
$19.99
Mac
Design your DMG on a canvas that shows exactly what users will see, then build a signed, production-ready disk image in one click. Templates included.
Design your DMG the way users will see it.
A disk image is the first thing anyone sees of your Mac app, and for years the only way to style one was to fight Finder, hand-place icons, and hope. Rilmazafone turns that into design. Lay out your installer on a WYSIWYG canvas that renders exactly what the mounted window will look like, then build a signed, production-ready DMG in one click.
WHAT YOU SEE IS WHAT SHIPS
Drag your app and its Applications shortcut into place on a canvas that mirrors the real Finder window: icon size, window bounds, grid spacing, and all. Alignment guides snap to centers, thirds, and neighboring icons. When you build, the mounted DMG matches the canvas pixel for pixel.
EFFECTS, NOT PHOTOSHOP
• Image, gradient, or solid backgrounds, stacked as layers
• Variable blur with linear or radial masks and live preview
• Vignette and bloom for depth and glow
• Text and SF Symbol layers composited straight into the background
• Per-icon frosted glass panels with shadow, bevel, and blend modes
• Retina-crisp output, rendered deterministically so every build machine produces the same background
START FROM A TEMPLATE
Nine bundled designs — Aurora, Classic, Compact, Cosmos, Editorial, Glass, Graphite, Snow Leopard, and Toolbox — each a working showcase of the layer system rather than a flat image. Pick one from the chooser, drop in your app, and build. Save any design of your own as a reusable template.
READABLE IN EVERY MODE
Finder colors item labels by system appearance: black in Light Mode, white in Dark. A background that reads perfectly in one can be invisible in the other, and it is the classic DMG mistake. Rilmazafone catches unreadable labels before your users do, flagging low-contrast labels per appearance and showing you exactly what is wrong with a light/dark canvas preview. No competitor warns about this.
COMING FROM ANOTHER TOOL
Import an existing DMG and Rilmazafone reconstructs the design (positions, window, background, icon size) as an editable document, or as a reusable template. Switch without starting over.
ONE-CLICK SIGNED BUILDS
Choose your compression (LZFSE, zlib, bzip2, or LZMA) and filesystem (APFS or HFS+), optionally sign with an identity detected automatically from your keychain, and build. Comprehensive undo covers every step along the way.
PRIVATE BY DEFAULT
No accounts, no telemetry, no network access. Rilmazafone collects nothing, and your designs never leave your Mac.
OPEN SOURCE
Rilmazafone is MIT-licensed and the full source code is on GitHub. Buying here gets you the convenient, sandboxed, notarized, auto-updating build and supports development.
