About Greenlight

Greenlight answers one question for Mac and iOS admins: is this Apple update safe to push to my fleet?

Greenlight is written for Apple admins who manage Macs, iPhones and iPads every day.

How verdicts work

Release facts (versions, builds, dates, CVE counts, actively exploited CVEs, and SOFA's expiration dates) come from the free public SOFA feeds by Mac Admins Open Source.
Verdicts are hand-written after checking Apple's enterprise and security notes, Jamf Nation, r/macsysadmin, r/Intune, Mr. Macintosh, and Microsoft's Intune docs. Every reported issue links to its source. When there's little evidence either way, the verdict says "no widespread issues reported" and lists what was checked.
A release we haven't reviewed shows yellow / not yet reviewed. An older build replaced by a newer one in the same major line shows grey / superseded.
Nothing goes green until it's 7+ days old. Before that, a clean release shows yellow / looking good, early, with the date it becomes eligible for green.
Deferral dates are simple arithmetic on the release date, so you can line them up with your own deferral policy.

Use RSS or the JSON API to pipe verdicts into Slack, Teams, or your own automation.

Verdicts are informational. Always pilot in your own environment. Not affiliated with Apple, Jamf, Microsoft, or Mac Admins Open Source.
