  ARM platforms using SoCs designed by Apple Inc., branded "Apple Silicon".

14


15
  This currently includes devices based on the "M1" SoC:

16


17
  - Mac mini (M1, 2020)

18
  - MacBook Pro (13-inch, M1, 2020)

19
  - MacBook Air (M1, 2020)

20
  - iMac (24-inch, M1, 2021)

21


22
  Devices based on the "M2" SoC:

23


24
  - MacBook Air (M2, 2022)

25
  - MacBook Pro (13-inch, M2, 2022)

26
  - Mac mini (M2, 2023)

27


28
  And devices based on the "M1 Pro", "M1 Max" and "M1 Ultra" SoCs:

29


30
  - MacBook Pro (14-inch, M1 Pro, 2021)

31
  - MacBook Pro (14-inch, M1 Max, 2021)

32
  - MacBook Pro (16-inch, M1 Pro, 2021)

33
  - MacBook Pro (16-inch, M1 Max, 2021)

34
  - Mac Studio (M1 Max, 2022)

35
  - Mac Studio (M1 Ultra, 2022)

36


37
  The compatible property should follow this format:

38


39
  compatible = "apple,<targettype>", "apple,<socid>", "apple,arm-platform";

40


41
  <targettype> represents the board/device and comes from the `target-type`

42
  property of the root node of the Apple Device Tree, lowercased. It can be

43
  queried on macOS using the following command:

44


45
  $ ioreg -d2 -l | grep target-type

46


47
  <socid> is the lowercased SoC ID. Apple uses at least *five* different

48
  names for their SoCs:

49


50
  - Marketing name ("M1")

51
  - Internal name ("H13G")

52
  - Codename ("Tonga")

53
  - SoC ID ("T8103")

54
  - Package/IC part number ("APL1102")

55


56
  Devicetrees should use the lowercased SoC ID, to avoid confusion if

57
  multiple SoCs share the same marketing name. This can be obtained from

58
  the `compatible` property of the arm-io node of the Apple Device Tree,

59
  which can be queried as follows on macOS:

60


61
  $ ioreg -n arm-io | grep compatible
