- 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.
However, attempts to run Intel-based containers on Apple Silicon machines can crash as QEMU sometimes fails to run the container. 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.
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/).
