@ -39,14 +39,14 @@ We expect to fix this in a future release.
However, attempts to run Intel-based containers on Apple Silicon machines can crash as QEMU sometimes fails to run the container. Filesystem change notification APIs (e.g. `inotify`) do not work under QEMU emulation, see [docker/for-mac#5321](https://github.com/docker/for-mac/issues/5321). Therefore, we recommend that you run ARM64 containers on Apple Silicon machines. These containers are also faster and use less memory than Intel-based containers.
We expect this issue to become less common over time, as more and more images are rebuilt [supporting multiple architectures](https://www.docker.com/blog/multi-arch-build-and-images-the-simple-way/).
- When using the `qemu` backend, `ping` from inside a container to the Internet does not work as expected. To test the network, we recommend using `curl` or `wget`. See [docker/for-mac#5322](https://github.com/docker/for-mac/issues/5322#issuecomment-809392861).
- ICMP echo responses (`ping` responses) can contain incorrect sequence numbers.
- Users may occasionally experience data drop when a TCP stream is half-closed.
### Fixes since Docker Desktop RC 3
- Docker Desktop now ensures the permissions of `/dev/null` and other devices are correctly set to `0666` (`rw-rw-rw-`) inside `--privileged` containers. Fixes [docker/for-mac#5527](https://github.com/docker/for-mac/issues/5527).
- Fixed an issue where ICMP echo responses (`ping` responses) had incorrect sequence numbers.
- Fixed an issue where data was dropped when a TCP stream was half-closed.
- Docker Desktop now reduces the idle CPU consumption.

**Mac with Apple silicon**
- **Mac with Apple silicon**: Docker Desktop now reduces the idle CPU consumption.
- Fixed an issue where ICMP echo responses (`ping` responses) had incorrect sequence numbers.
- Fixed an issue where data was dropped when a TCP stream was half-closed.
- Docker Desktop now reduces the idle CPU consumption.
### Known issues
**Apple silicon**
- Not all images are available for ARM64 architecture. You can add `--platform linux/amd64` to run an Intel image under emulation. In particular, the [mysql](https://hub.docker.com/_/mysql?tab=tags&page=1&ordering=last_updated) image is not available for ARM64. You can work around this issue by using a [mariadb](https://hub.docker.com/_/mariadb?tab=tags&page=1&ordering=last_updated) image.
