然后我卸载它并使用cask重新安装

第二种方法

brew install --cask docker

MacOS Catalina - 10.15.7

尝试从https://www.docker.com/products/docker-desktop下载DMG，并按照通常的方式安装它。 - Nikolai Shevchenko

如何在 MacOS headless 机器上安装它？我参加了 Gitlab MacOS Builder beta 计划，但无法通过命令行进行安装。与上述相同的错误... 它无法连接到本地 docker 容器。 - Marcello DeSales

Answer 1

以下是带有下载链接的Docker Desktop发行说明：

https://docs.docker.com/desktop/release-notes/

4.16.0: (2023-01-12)

现在，在 macOS 上安装或更新 Docker Desktop 的最低操作系统版本是 macOS Big Sur（版本 11）或更高版本。

因此，Catalina（10.15.7）的最后可运行版本应该是 4.15.0，可以从此页面下载。

URL 不会永久存在，总有一天，本答案将变得无效。我记录了目标 URL，以防它们存在更长的时间。

• https://desktop.docker.com/mac/main/amd64/93002/Docker.dmg
• https://desktop.docker.com/mac/main/arm64/93002/Docker.dmg

在Catalina中，最有可能的是第一个链接（amd64）。

作为最后的手段，搜索引擎可以通过校验和发现文件：

Mac Intel: SHA-256 bee41d646916e579b16b7fae014e2fb5e5e7b5dbaf7c1949821fd311d3ce430b

Mac Arm: SHA-256 fc8609d57fb8c8264122f581c0f66497e46e171f8027d85d90213527d6226362

这对我真的很有帮助。 - undefined

Answer 2

似乎 Docker Desktop 4.16 不再支持 macOS Catalina（10.15）。

如果您不想升级到新的 macOS 版本，可以安装旧版本的 Docker Desktop，该版本仍可在 macOS Catalina 上运行。 Docker Desktop 4.15 可在 Catalina 上运行。

您可以使用 Homebrew 进行安装。

# Download Cask code for Docker Desktop 4.15.0,93002
curl https://raw.githubusercontent.com/Homebrew/homebrew-cask/1a83f3469ab57b01c0312aa70503058f7a27bd1d/Casks/docker.rb -O

# Install Docker Desktop from Cask Code
brew install --cask docker.rb

# OR

# if Docker Desktop is already installed then reinstall from Cask Code
brew reinstall --cask docker.rb
