ARM platforms using SoCs designed by Apple Inc., branded "Apple Silicon".
This currently includes devices based on the "M1" SoC:
- Mac mini (M1, 2020)
- MacBook Pro (13-inch, M1, 2020)
- MacBook Air (M1, 2020)
- iMac (24-inch, M1, 2021)
And devices based on the "M1 Pro", "M1 Max" and "M1 Ultra" SoCs:
- MacBook Pro (14-inch, M1 Pro, 2021)
- MacBook Pro (14-inch, M1 Max, 2021)
- MacBook Pro (16-inch, M1 Pro, 2021)
- MacBook Pro (16-inch, M1 Max, 2021)
- Mac Studio (M1 Max, 2022)
- Mac Studio (M1 Ultra, 2022)
The compatible property should follow this format:
compatible = "apple,<targettype>", "apple,<socid>", "apple,arm-platform";
<targettype> represents the board/device and comes from the `target-type`
property of the root node of the Apple Device Tree, lowercased. It can be
queried on macOS using the following command:
$ ioreg -d2 -l | grep target-type
<socid> is the lowercased SoC ID. Apple uses at least *five* different
names for their SoCs:
- Marketing name ("M1")
- Internal name ("H13G")
- Codename ("Tonga")
- SoC ID ("T8103")
- Package/IC part number ("APL1102")
Devicetrees should use the lowercased SoC ID, to avoid confusion if
multiple SoCs share the same marketing name. This can be obtained from
the `compatible` property of the arm-io node of the Apple Device Tree,
which can be queried as follows on macOS:
$ ioreg -n arm-io | grep compatible
