### Legacy Mac OS X

Intel board IDs for 10.9 Mavericks. Results are sourced from both the primary and legacy DynamoDB tables, so PowerPC model numbers (e.g. `M5183`, `M4984`) appear alongside Intel board IDs for versions that span both 68k-era and Intel-era Macs.

## Response Fields

<ResponseField name="macos_version" type="string">
  The version string as provided in the request path.
</ResponseField>

<ResponseField name="major_version" type="string">
  The inferred major version (e.g. `"7.1"` from `"7.1.1"`, `"12"` from `"12.3.2"`).
</ResponseField>

<ResponseField name="compatible_board_ids" type="array of strings">
  A sorted list of every board ID (Apple hardware identifier) that supports this macOS major version.

  Board ID formats vary by Mac era:

  * **Apple Silicon & Intel (modern):** `J293AP`, `Mac-35C5E08120C7EEAF`, etc.
  * **Virtual machines:** `VMA2MACOSAP`, `VMM-x86_64`
  * **PowerPC Mac OS X (10.0–10.5):** Apple model numbers (e.g. `M5183`, `A1047`, `M8493`, `M6498`)
  * **Classic Mac OS (System 0.97–Mac OS 9.2.2):** Apple model numbers (e.g. `M0001`, `M5521`, `M7777`, `M1688`)
</ResponseField>

<ResponseField name="count" type="integer">
  The total number of board IDs in the `compatible_board_ids` array.
</ResponseField>

## Notes

* Results are sourced from both the primary and legacy DynamoDB tables and merged into a single unified list. This ensures full coverage for older macOS versions.
* Board IDs are sorted alphabetically.
* A `404` is returned if no board IDs are found for the specified version.
