+| `alt_system_info` | Alternative system_info table | macOS | This table is an alternative to the built-in system_info table in osquery, which triggers an `Allow "osquery" to find devices on local networks?` prompt on macOS 15.0. On versions other than 15.0, this table falls back to the built-in system_info table. Note: this table returns an empty `cpu_subtype` field. See [#58](https://github.com/macadmins/osquery-extension/pull/58) for more details. |
