Privacy rebuild: the Mac downloads were reissued on September 12, 2026 to remove local build paths and an obsolete bundled script. Re-download the Mac app if you obtained an earlier copy. Quick Scan 1.1 is unchanged.

Macus 0.4.0 keeps the Mac application small and distributes PC diagnostics separately. Quick Scan 1.1 boots from a regular USB, collects inventory and basic health data, saves reports to that same USB, and shuts down automatically.

Downloads

  • Macus-0.4.0-arm64.dmg — Mac installer: open it and drag Macus into Applications. Requires Apple Silicon and macOS 26 or later.
  • Macus-0.4.0-arm64.zip — the same Mac application as a ZIP.
  • Macus-QuickScan-USB.img.zip — separate Intel/AMD PC boot image. Extract it, keep the .img and .sha256 together, and select the image in Macus under Inventory & Diagnostics.
  • SHA256SUMS.txt — checksums for these downloads. The boot-image ZIP also contains a checksum for the extracted image.

Back up existing reports before recreating a USB; writing an image erases the selected drive. Use a regular USB of 2 GB or larger. Ventoy is optional, not required. Reports accumulate under MacusReports; reconnect the USB to the Mac to import them. Full Diagnostics remains available from the boot menu.

Changes

  • Select a separate diagnostics image instead of bundling hundreds of megabytes inside the Mac app.
  • Native authorized USB writing, fresh destination checks, checksum verification and automatic ejection.
  • CPU/GPU inventory, RAM type/modules/speed, HDD/SSD capacity/interface, SMART and battery readings.
  • Quick Scan 1.1: clearer model names and capacities, scan timing, NVMe wear/error counters, driver-reported GPU memory where available, and explicit warnings for unverified or suspect PC clocks.
  • Failed saves leave the PC on with an error; successful repeated scans preserve previous reports.

Validation and limits

32 Swift and 22 Python tests pass. The published Quick Scan image passed BIOS/UEFI virtual boots, repeated saves on the same USB, and save-failure handling. Internal virtual HDD/SSD contents remained unchanged. DMG integrity, application signature and download checksums were verified locally.

Quick Scan 1.0 was tested on a physical ThinkPad P15 Gen 2i. The 1.1 update still needs a small physical pilot across different PCs, including GPU-memory verification. Secure Boot compatibility is not verified. Hardware detection and basic SMART readings are not stress tests or a complete hardware certification; unknown data stays unknown. Windows installer testing is separate from diagnostics validation.

The Mac application is Developer ID signed and Apple-notarized. The app and DMG carry stapled notarization tickets and pass local Gatekeeper assessment. Re-download the app if your copy predates this notarized reissue. Checksums verify download integrity; the Apple-verified signature identifies the publisher. No Windows or other proprietary OS installer is included.
