You are testing the KOTA sensorbox technician tool v0.8 on macOS. The current folder is
004-technician_tool/v0.8 (a Python/PySide6 desktop app; tested on Windows 11, macOS paths are covered by
unit tests but not yet run on a real Mac).

Rules:
- Python only via uv or conda/mamba. Never use bare/system python or pip.
- Do not build or modify firmware. Flash only files from the tool's firmware/ folder.
- Do not push anything to Git or GitLab. This is a local demo.
- Ask me before any destructive action: formatting an SD card, Full-mode flashing, or deleting files.
  Before formatting, show me the exact disk (identifier, name, size, current files).
- Do not change code without telling me. Report bugs with evidence (commands and output).

Tests, in order. Report pass/fail with evidence for each:
1. Launch: `bash run_macos.command` (it offers to install uv). The app window opens; note any warnings.
   Also check whether a double-click in Finder works (Google Drive may drop the executable bit).
2. Tests: `UV_PROJECT_ENVIRONMENT="$HOME/Library/Caches/KotaTechnicianTool/venv-0.8" uv run --frozen pytest -q`
   (expect 172 passed).
3. Serial: plug in the sensorbox (native USB). The port list shows a /dev/cu.usbmodem* "Sensorbox (native USB)"
   entry with a MAC (no /dev/tty.* duplicate). Connect, press "Reset & capture": the log starts at
   "ESP-ROM:esp32s3" and the Diagnosis panel shows firmware v1.0.16 (build 4f10989e), the "Box self-report"
   section and the LED with its pattern. Check whether the port disappears after the reset and whether the
   tool reconnects. Wait 2 minutes: a "KOTA: health" line appears every 60 s.
4. Show filter "KOTA diagnostics + errors" shows only KOTA lines and errors.
5. Guided troubleshooting: run "Quick check" and answer truthfully with what I tell you the LED shows.
6. Flash (App only, the newest file in firmware/, chosen by its compile date): the tool must enter flashing mode
   by itself, write, restart the box and report "Success ... build 4f10989e". Capture the esptool output.
7. SD card tab: the card reader and card are listed (internal disks must NOT be listed). "Check card" must NOT
   report a wrong file system for a FAT32 card. After my OK, "Format card and write ENV.TXT" must use
   `diskutil eraseDisk FAT32 KOTA MBRFormat` on the correct disk, write ENV.TXT and eject the card.
8. "Service report..." opens the browser at https://service.kota-app.com/<MAC>#kota-report=...; the note in
   the form must match the Diagnosis panel (self-report, start-up progress with times, findings with
   "Seen Nx, first at ... s").

At the end, write a short report: macOS version, Mac model/architecture, each test with result, errors, and
suggested fixes (file:line).
