Docker Desktop 4.15.0 Release: Enhancements, Bug Fixes, and Known Issues for Mac and Windows

- Fixed actions on compose stack not working properly. Fixes [docker/for-mac#6566](https://github.com/docker/for-mac/issues/6566). - Fixed the Docker Desktop Dashboard trying at startup to get disk usage information and display an error banner before the engine was running. - Added an informational banner with instructions on how to opt-out of experimental feature access next to all experimental features. - Docker Desktop now supports downloading Kubernetes images via an HTTP proxy. - Fixed tooltips to not block action buttons. Fixes [docker/for-mac#6516](https://github.com/docker/for-mac/issues/6516). - Fixed the blank "An error occurred" container list on the **Container** view. #### For Mac - Minimum OS version to install or update Docker Desktop on macOS is now macOS Big Sur (version 11) or later. - Fixed the Docker engine not starting when Enhanced Container Isolation is enabled if the legacy `osxfs` implementation is used for file sharing. - Fixed files created on VirtioFS having the executable bit set. Fixes [docker/for-mac#6614](https://github.com/docker/for-mac/issues/6614). - Added back a way to uninstall Docker Desktop from the command line. Fixes [docker/for-mac#6598](https://github.com/docker/for-mac/issues/6598). - Fixed hardcoded `/usr/bin/kill`. Fixes [docker/for-mac#6589](https://github.com/docker/for-mac/issues/6589). - Fixed truncation (for example with the `truncate` command) of very large files (> 38GB) shared on VirtioFS with an incorrect size. - Changed the disk image size in **Settings** to use the decimal system (base 10) to coincide with how Finder displays disk capacity. - Fixed Docker crash under network load. Fixes [docker/for-mac#6530](https://github.com/docker/for-mac/issues/6530). - Fixed an issue causing Docker to prompt the user to install the `/var/run/docker.sock` symlink after every reboot. - Ensured the Login Item which installs the `/var/run/docker.sock` symlink is signed. - Fixed bug where `$HOME/.docker` was removed on factory reset. ### For Windows - Fixed `docker build` hanging while printing "load metadata for". Fixes [docker/for-win#10247](https://github.com/docker/for-win/issues/10247). - Fixed typo in diagnose.exe output Fixes [docker/for-win#13107](https://github.com/docker/for-win/issues/13107). - Added support for running under cgroupv2 on WSL 2. This is activated by adding `kernelCommandLine = systemd.unified_cgroup_hierarchy=1 cgroup_no_v1=all` to your `%USERPROFILE%\.wslconfig` file in the `[wsl2]` section. ### Known Issues - Calling `sudo` inside a container fails with a security related error for some images. See [docker/for-mac/6675](https://github.com/docker/for-mac/issues/6675) and [docker/for-win/13161](https://github.com/docker/for-win/issues/13161). ## 4.15.0 {{< release-date date="2022-12-01" >}} ### New - Substantial performance improvements for macOS users with the option of enabling the new VirtioFS file sharing technology. Available for macOS 12.5 and above. - Docker Desktop for Mac no longer needs to install the privileged helper process `com.docker.vmnetd` on install or on the first run. For more information see [Permission requirements for Mac](https://docs.docker.com/desktop/mac/permission-requirements/). - Added [WebAssembly capabilities](/manuals/desktop/features/wasm.md). Use with the [containerd integration](/manuals/desktop/features/containerd.md). - Improved the descriptions for beta and experimental settings to clearly explain the differences and how people can access them. - Available disk space of VM now displays in the footer of Docker Desktop Dashboard for Mac and Linux. - A disk space warning now displays in the footer if available space is below 3GB. - Changes to Docker Desktop's interface as we become more ADA accessible and visually unified. - Added a **Build** tab inside **Extensions** which contains all the necessary resources to build an extension. - Added the ability to share extensions more easily, either with `docker extension share` CLI or with the share button in the extensions **Manage** tab.

This section details fixes and enhancements in Docker Desktop for Mac and Windows. General fixes include Compose stack actions, Docker Desktop Dashboard errors, experimental feature banners, Kubernetes image downloads via HTTP proxy, and tooltip issues. Mac-specific updates include OS version requirements, Docker engine startup issues with Enhanced Container Isolation, VirtioFS file handling, command-line uninstallation, file truncation fixes, disk image size display, and Docker crash fixes. Windows updates address `docker build` hanging, typo corrections, and cgroupv2 support on WSL 2. Known issues involve `sudo` failures inside containers. Docker Desktop 4.15.0 introduces performance improvements for macOS with VirtioFS, removes the need for the privileged helper process, adds WebAssembly capabilities, improves descriptions for beta and experimental settings, displays VM disk space, improves ADA accessibility, and enhances extension sharing.
