PatternSpace

Purpose: PatternSpace is a macOS test pattern generator for display calibration that renders SDR and HDR patches, pattern grids, clipping checks, gamma tools, and color swatches.
Intended users: The maker describes it as designed for display calibrators, reviewers, video engineers, and home theater installers who need predictable pattern output from a Mac.
Pattern library: It includes more than 100 GPU-rendered patterns across Color, Checks, Geometry, Swatch, Gamma, and Clipping categories.
Rendering: The app uses a Metal EDR pipeline with up to 16-bit-per-channel rendering and vsync-locked patch output.
Calibration integrations: Pro supports ColourSpace Network Server, CalMAN UPGCI, and PGenerator network automation.
Remote protocol: PatternSpace Remote is an openly documented WebSocket/JSON-RPC protocol with 4-digit pairing; its free evaluation allows up to 25 rendered patches per session.
Display support: The app supports connected internal or external displays and requires macOS 15.6 or later on Apple Silicon or Intel Macs.
Security: The maker says the app is sandboxed, limits network traffic to calibration protocols on the local network, and sends no analytics or telemetry to the internet.
Permissions: The maker states that the app does not access the camera, microphone, location, or Bluetooth, and uses read-only access to user-selected files.
LUT tools: LUT Tools is marked beta; inspecting and building chains is free, while writing LUT or ICC files requires Pro.
Calibration limitation: PatternSpace provides patches but does not measure or automatically correct a display; display accuracy requires measurement hardware.
SDI limits: DeckLink SDI output supports specified progressive 720p/1080p SDR modes; library patterns and HDR/UHD SDI are not supported.
