Publish provenance Add package provenance or release attestations so users can verify where shipped artifacts came from.
Increase signed commits Raise the share of verified-signed commits to make maintainer identity and release history easier to trust.
Refresh maintenance signals The repo was last pushed 33 days ago. Fresh activity helps separate stable projects from stale ones.

How to read this: HVTrust (0–100) weighs supply-chain signals (provenance, OSSF Scorecard, signed commits, open license) alongside real-world adoption. Grade D reflects the trust score band: A ≥ 80, B ≥ 65, C ≥ 50, D < 50. Evidence coverage D is separate — it grades how many independent signal types back the score (1 of 5), so a high score on thin evidence stays visible. Full methodology →

Is macOS Calendar and Reminders safe?

Public trust evidence for macOS Calendar and Reminders is thin: several supply-chain signals are missing or weak. This does not mean the project is unsafe — it means an outside observer cannot easily verify the usual integrity checks. Treat with extra scrutiny.
Does macOS Calendar and Reminders publish package provenance?
No published build provenance is currently detected for macOS Calendar and Reminders. This is common for open-source projects but means consumers cannot independently verify that the package on the registry matches the GitHub source.
Does macOS Calendar and Reminders have an OpenSSF Scorecard?
No OpenSSF Scorecard data is currently published for macOS Calendar and Reminders. Maintainers can enable the Scorecard GitHub Action to get a public score; without it, automated supply-chain hygiene is harder for outsiders to verify.
Is macOS Calendar and Reminders actively maintained?
Slowing down. Last push was 33 days ago — keep an eye on whether activity resumes.
What license does macOS Calendar and Reminders use?
macOS Calendar and Reminders ships under MIT. A declared, OSI-approved license is one of the transparency signals HVTrust scores.
Are macOS Calendar and Reminders's commits signed?
41% of the last 100 commits to macOS Calendar and Reminders are verified-signed (GPG, SSH, S/MIME, or GitHub's signing flow). Signed commits help confirm that code was authored by who the commit claims.

Not a safety endorsement. HVTracker describes what public signals show, not whether a project is safe for your use case. Run your own security review before adopting in production.

Maintain macOS Calendar and Reminders?

For maintainers

HVTrust scores macOS Calendar and Reminders from public signals only — we never contact maintainers first. If a signal is wrong, stale, or missing (provenance you publish, a Scorecard you run, signed releases), tell us and we'll review it. Corrections are public and tracked on GitHub.
