MacNativeGames
Runs with mockssource: GitHubCMITcommit 30a1b93d0776
C, MIT licensed.
MacNativeGames runs, with stand-ins for the services it depends on. An Argusic agent installed it in 6.8 minutes and hit 8 errors and fixed every one without help on a clean machine with no GPU, and the whole session was recorded.
All 256 tests run without failures (217 passed, 39 skipped as expected on Linux). The build_app.py clonefile function gracefully degrades to shutil.copy2 on non-macOS; the test suite handles Linux-compatible .venv setup, codesign/data_bundle mocking, and lazy imports for missing Python 3.14 modules.
What the agent ended up with on a clean machine, in its own words. How this is measured
Measured by Argusic on a fresh machine every time. Every number links to its evidence. Argusic Score 86 of 100 (the mean of this project's run scores).

What was measured
From the run that decided this verdict. Every line is a recorded value, not an estimate.
What went wrong, in the agent's own words
The agent's own words, worst first, never rewritten into advice.
- test_updates.py symlinked .venv to sys.prefix (/usr) but /usr/bin is read-only; also called step_app without patching data_bundle which runs codesign1.5 minutes
- build_app.clonefile() failed on Linux because clonefile(2) is macOS-only (undefined symbol: clonefile in libc)1.2 minutes
- test_build_mod.py's mergeable_overlays() failed because make_romfs_patches imports compression.zstd at module level0.8 minutes
- test_app_game_data.py used os.stat_result.st_birthtime which does not exist on Linux0.5 minutes
- test_botw_import.py called step_app which invoked data_bundle and then codesign (macOS-only)0.5 minutes
- games/botw/scripts/location_markers.py imported sarc_members from make_romfs_patches at module level, which fails without compression.zstd0.5 minutes
- Install time
- 7 minutes
- Cold machine to finish
- 15 minutes
- Errors hit and fixed
- 8 hit, 8 fixed with no human help
- How the result was proved
- python3 -m unittest discover -s tests exited 0; 256 tests ran, 217 passed, 39 skipped (all expected macOS/Xcode/Python 3.14-only tests)
- Model tokens used

What was not measured
The other half, so you can see exactly how far this evidence goes. A gap is printed as a gap and never filled in.
- Peak GPU memory
- this ran on a CPU machine, so there was no GPU to sample
- Behaviour over a long run
- each attempt uses the smallest documented settings and a fixed time budget, so this measures whether it runs, not how it holds up under load
- Behaviour against real services
- this run was verified against stand-in services only
The end of the recording
The last lines of the terminal session that decided this verdict, exactly as they were recorded.
7. **`test_botw_import.py`**: Patched `data_bundle` in the test that calls `step_app` 8. **`games/botw/scripts/location_markers.py`**: Made `sarc_members` import lazy to avoid importing… Now let me provide the final result: exec /bin/sh -lc 'cd /work/repo && python3 -m unittest discover -s tests 2>&1 | grep -E "''^Ran|''^OK|''… succeeded in 6789ms: Ran 256 tests in 6.792s OK (skipped=39) Let me compute the total time and produce the final report. tokens used 641,588 Let me compute the total time and produce the final report.
Replay the whole session, every command from a clean machine to this point.
How it was tested
One agent, one container, no human help. It installs the project the way its own documentation says to, runs it, and fixes what breaks. Everything below is recorded as it happened: the terminal session, the log and the exact commit. The full method.
Strengths and limits
Measured facts, not opinions. How this is written.
What went well
- Installed in 6.8 minutes, faster than the median of the 5 comparable projects Argusic has measured.
- Recovered from all 8 errors without a human stepping in, which says the failures are documented well enough to solve.
- Licensed MIT, as reported by its host.
- Measured 2 times, so the result is not a one-off.
What did not, or is not known
- Only reached a running state against stand-in services, so nothing here proves it works against the real ones.
Of the 6 C projects Argusic has installed and timed, MacNativeGames was the 3rd fastest to reach a running state, and 5 of 6 reached one at all.

[](https://argusic.com/subject/macnativegames)Questions
- Does MacNativeGames run?
- MacNativeGames runs, with mocks standing in for external services. Argusic installed and launched it on a clean machine in 7 minutes, hitting 8 errors on the way, and recorded the session.
- How did Argusic test MacNativeGames?
- On a fresh, disposable machine, with every command recorded and the repository pinned at commit 30a1b93d0776. 2 attempts are recorded, and the full method is on the methodology page.
- What did it cost to test MacNativeGames?
- The run that produced this verdict cost $0.20: real compute and model cost, not a list price per million tokens. It is recorded on that run's page.
- How long does MacNativeGames take to install?
- 6.8 minutes in the run that decided this verdict, from a clean machine to a running state. That is one measured attempt, not an average.
- Does MacNativeGames need a GPU?
- Not to start. Argusic reached a running state on a machine with no GPU.
- What goes wrong when installing MacNativeGames?
- 8 things broke in the recorded run, and 8 were fixed without human help. Each one, and the time it cost, is listed on this page.
- How does MacNativeGames compare with the alternatives?
- Of the 6 C projects Argusic has installed and timed, MacNativeGames was the 3rd fastest to reach a running state, and 5 of 6 reached one at all.
- Where is the evidence for MacNativeGames?
- All 2 recorded runs are on this page, each linking to its full log and terminal recording, stored with a sha256 fingerprint so it cannot be quietly altered.
