Lima is a virtualization tool that enables macOS users to create a Linux virtual machine environment similar to WSL2 on Windows, allowing access to Linux systems while maintaining file and port availability. Powered by QEMU, Lima can be used as an alternative to Docker Desktop for running containers on macOS. The setup involves installing Lima via Homebrew, selecting a VM template like ubuntu-lts, and configuring file system access, which, while typically read-only, can be adjusted for writable access with caution. Despite potential file system performance concerns reported by some users, the author did not experience such issues during limited use. Additionally, integrating Lima with Earthly can enhance build processes on macOS, providing an efficient and streamlined experience.
