What you see here, and what you do not
The status is derived from the patch history: did this device get the most recent round that covered its product line, yes or no.
Since this device was last updated, 169 security updates were published for newer devices in the same line.
We only say this beyond two measured thresholds: more than 21 missed rounds, or more than 973 days of silence. Those are the largest values after which any device in our entire history still came back. This one is at 169 missed rounds and 3694 days.
We do not know an end-of-support date for this device. Apple does not publish one. Once the EU product database EPREL provides it, an expected end date will appear here — right now that would be a guess.
Our data starts with advisories from 1 January 2013. Advisories before that use a notation we deliberately do not parse, so this device’s history may start earlier than shown here.
