rx no.004 ・ a prodrug for the disk image

The installer, drawn.

A disk image is the first thing anyone sees of your Mac app. Lay yours out on a canvas that mirrors the mounted Finder window — icon size, grid, bounds and all — then build a signed .dmg in one click.

Rilmazafone's canvas: a DMG install window laid out with an app icon and an Applications shortcut, with the layer sidebar on the left and the effects inspector on the right — **the canvas** ・ what you draw is what mounts

directions for use

01What you see is what ships. Drag icons where Finder will show them. Guides snap to centers, thirds, and neighbors.

02Backgrounds as layers. Images, gradients, or solid colors — with color adjustments, vignette, and bloom.

03Variable blur. Linear or radial masks, live on the canvas.

04Text and symbols. Styled text and SF Symbols composited straight into the background.

05Glass under the icons. Per-icon frosted panels with shadow, bevel, and blend modes — so names stay legible on any background.

06Then build. UDZO, UDBZ, LZFSE, or LZMA; HFS+ or APFS; signed with an identity from your keychain.

A prodrug is inert until something converts it. This one waits for Build.
