+## Dropped support for Intel Macs
+We've dropped official support for Intel (x86) maxOS in [PR #11719](https://github.com/rerun-io/rerun/pull/11719).
+
+This means our Python pheels on PyPi.org and our other pre-built artifact does no longer include Intel Mac binaries.
+
+You can still build Rerun from source.
+There are instructions for that in [`BUILD.md`](https://github.com/rerun-io/rerun/blob/main/BUILD.md).
+
+
 ## Python SDK: minimum supported Python 3.10
 
 Support for Python 3.9 is past end-of-life.
 See https://docs.python.org/3/whatsnew/3.10.html for more details on upgrading to 3.10 if necessary.
