 | Platform | Status | Notes |
 |----------|--------|-------|
-| Linux x86_64 / ARM64 | ✅ Supported | Full embedded mode support via `pylibseekdb` |
-| macOS 15+ on Apple Silicon | ✅ Supported | Requires the macOS ARM64 `pylibseekdb` wheel |
-| macOS 14 or earlier on Apple Silicon | ❌ Not currently supported | The published native wheel requires macOS 15+; follow [oceanbase/seekdb#1324](https://github.com/oceanbase/seekdb/issues/1324) |
-| macOS on Intel | ❌ Not currently supported | No embedded binding is selected by `pyseekdb` |
-| Windows | ❌ Not currently supported | No Windows `pylibseekdb` wheel is published |
+| Linux | ✅ Supported | Full embedded mode support via `pylibseekdb` |
+| macOS | ❌ Not Supported | `pylibseekdb` is Linux-only; use server mode instead |
+| Windows | ❌ Not Supported | `pylibseekdb` is Linux-only; use server mode instead |

-**Important**: Embedded mode requires a compatible `pylibseekdb` wheel. Do not

+**Important**: Embedded mode requires the `pylibseekdb` library, which is only available on Linux. If you're on macOS or Windows, you must use server mode.

 ### Server Mode (Docker)

 | Platform | Status | Notes |
 |----------|--------|-------|
 | Linux | ✅ Supported | Full Docker support |
-| macOS | ✅ Supported by Docker Desktop | The previous slow-disk startup issue was fixed upstream in [oceanbase/seekdb#36](https://github.com/oceanbase/seekdb/issues/36) |
-| Windows | ⚠️ Depends on the container runtime | Use a Linux container and follow the upstream image documentation |
+| macOS | ⚠️ Known Issue | Docker container initialization failure - [See Issue #36](https://github.com/oceanbase/seekdb/issues/36) |
+| Windows | ⚠️ Untested | Should work but not yet tested |
+
+**macOS Users**: Currently, SeekDB Docker containers have an initialization issue on macOS ([oceanbase/seekdb#36](https://github.com/oceanbase/seekdb/issues/36)). Until this is resolved, we recommend:
+- Using ChromaDB or Qdrant as alternatives
+- Connecting to a remote SeekDB server on Linux if available

 ### Server Mode (Remote Connection)

 | Platform | Status | Notes |
 |----------|--------|-------|
-| Linux | ✅ Supported | Install the `seekdb` extra and connect to the remote server |
-| macOS 15+ on Apple Silicon | ✅ Supported | Install the `seekdb` extra and connect to the remote server |
-| macOS 14 or earlier on Apple Silicon | ⚠️ Blocked by upstream packaging | `pyseekdb` currently requires the unavailable native wheel even for server-only use; follow [#1324](https://github.com/oceanbase/seekdb/issues/1324) |
-| macOS on Intel / Windows | ✅ Server mode only | Embedded bindings are not available |
+| All Platforms | ✅ Supported | Connect to SeekDB running on a remote Linux server |

-Remote server mode does not use embedded storage at runtime. However, whether
-the Python client can be installed still depends on `pyseekdb`'s package
