Feature Support¶

Apple sells one marketing name across several different chips, and puts one chip in several different machines. Support has to be tracked per machine, so this section is organised the way the hardware actually is rather than the way it is advertised.

How Apple hardware is identified¶

Three names matter, and they don't map one to one.

Name	Looks like	What it identifies
Marketing name	M1 Pro, M4, A18 Pro	What Apple sells the chip as
SoC ID	`t6000`	The chip itself
Device ID	`j316s`	One specific machine

A 16-inch MacBook Pro from 2021 is device j316s, its chip is t6000, and Apple calls that chip the M1 Pro. The 14-inch model from the same launch is a different machine, j314s, running the same chip. The two share silicon but not an enclosure, a display, or a set of peripherals — so they are catalogued separately.

Device IDs sometimes carry a suffix that distinguishes chip bins within one enclosure: j314s is the M1 Pro 14-inch, j314c the M1 Max version of the same laptop. Where Apple shipped two configurations that differ in ways the firmware can see — port count on the iMac, core count on the M3 Max — each gets its own device ID.

Reading a support state¶

Support states are not recorded yet

The catalog below identifies hardware; it does not yet claim anything about what works. Per-machine support states, and the legend that goes with them, still need to be defined and filled in.

Two rules apply once states do appear here. A state is recorded against a device ID, not a marketing name — "M2 Pro works" is not a claim this section can make, because the M2 Pro appears in four different machines. And a result on one machine never transfers to a sibling, however similar: the chip may be shared, but the board, display, and peripherals are not.

Where the identifiers come from¶

Device and SoC IDs on this page are taken from the Apple device trees in the Linux kernel and from the Asahi Linux SoC codename table, which is the reference for chips that do not yet have upstream device trees.
