# GET /items/{boardID}

> Retrieve all macOS major versions supported by a given board ID.

Returns a comma-separated list of every macOS major version that the specified board ID (Mac model) has ever supported. Useful for quickly checking what macOS versions a given Mac is compatible with.

## Endpoint

```http theme={null}
GET https://proximosapi.enlazosystems.com/items/{boardID}
Authorization: YOUR_DECODED_LICENSE_KEY
```

## Path Parameter

<ParamField path="boardID" type="string" required>
  The Apple board identifier for the Mac model. Must start with a letter and contain no periods or colons.

  | Era                          | Example board IDs                              |
  | ---------------------------- | ---------------------------------------------- |
  | Apple Silicon                | `J293AP`, `J413AP`, `J316cAP`, `J493AP`        |
  | Intel                        | `Mac-35C5E08120C7EEAF`, `Mac-4B682C642B45593E` |
  | PowerPC Mac OS X (10.0–10.5) | `M5183`, `A1047`, `M8493`, `M6498`, `A1103`    |
  | Classic Mac OS 68k           | `M0001`, `M5119`, `M1476`, `M7777`, `M4300`    |
  | Classic Mac OS PPC           | `M1688`, `M3979`, `M5521`, `M4984`, `M8570`    |
  | Virtual machines             | `VMA2MACOSAP`, `VMM-x86_64`                    |

  <Note>
    For Motorola 68k and PowerPC Macs, the board ID is the Apple model number physically printed on the machine (e.g. `M5521` for all iMac G3 350–700 MHz slot-loading models). These are verified against EveryMac.com. Where Apple assigned one model number to multiple machines, the database entry covers the union of their supported OS versions.

## Responses

### Modern macOS

`J293AP` is the M1 MacBook Pro (14-inch, 2021). Apple Silicon Macs start at macOS 11 Big Sur.

```json theme={null}
{
  "board_id": "J293AP",
  "supported_macOS": "11.0, 12.0, 13.0, 14.0, 15.0, 26.0"
}
```

### Legacy Mac OS X

`Mac-F4208EAA` is an early Intel iMac that shipped with Mac OS X 10.5 Leopard and received updates through OS X 10.11 El Capitan.

```json theme={null}
{
  "board_id": "Mac-F4208EAA",
  "supported_macOS": "10.5, 10.6, 10.7, 10.8, 10.9, 10.10, 10.11"
}
```

### Classic Mac OS

`M7777` is the Apple model number shared by all PowerBook Duo models (210, 230, 250, 270c, 280, and 280c). The union OS range spans System 7.0 through System 7.6.1, as the 68LC040-based Duo 280 and 280c raised the maximum from 7.5.5.

```json theme={null}
{
  "board_id": "M7777",
  "supported_macOS": "7.0, 7.1, 7.5, 7.6"
}
```

## Response Fields

<ResponseField name="board_id" type="string">
  The board ID from the request path.
</ResponseField>

<ResponseField name="supported_macOS" type="string">
  A comma-separated, version-sorted list of every macOS major version supported by this board ID. Results are sourced from both the primary and legacy DynamoDB tables, so a single model number that spans both Classic Mac OS and Mac OS X eras (such as `M5521` for iMac G3) will return versions from both.

  Version formatting by era:

  * **Modern macOS:** `X.0` suffix (e.g. `14.0`, `26.0`)
  * **Legacy Mac OS X:** `10.Y` format (e.g. `10.9`, `10.15`)
  * **Classic Mac OS:** as-is (e.g. `8.5`, `9.2`, `7.1`)
</ResponseField>

## Notes

* The API returns a `404` if no records are found for the given board ID.
* Major versions are sorted in ascending order.
* Results are sourced from both the primary and legacy DynamoDB tables.
* To look up the latest release for a specific major version on this board, use [GET /items/](/proximos-api/endpoints/get-boardid-major){boardID}[:](/proximos-api/endpoints/get-boardid-major){majorVersion}. To look up the latest release for a specific major version on this board, use [GET /items/](/proximos-api/endpoints/get-boardid-major){boardID}[:](/proximos-api/endpoints/get-boardid-major){majorVersion}.

## Finding Your Mac's Board ID

You can find a modern Intel or Apple Silicon Mac's board ID from the command line:

```bash theme={null}
ioreg -d2 -c IOPlatformExpertDevice | grep board-id
```

Or use it in an MDM script:

```bash theme={null}
board_id=$(ioreg -d2 -c IOPlatformExpertDevice | awk -F'"' '/board-id/{print $4}')
curl -H "Authorization: YOUR_DECODED_LICENSE_KEY" \
  "https://proximosapi.enlazosystems.com/items/${board_id}"
```

For PowerPC and 68k Macs, the board ID is the Apple model number printed on the underside or back of the machine (e.g. `M5521`, `A1047`).
