Docker for Mac has the following system requirements:
- macOS El Capitan 10.11, or a newer macOS release
- At least 4 GB of RAM
- The Mac hardware must be a 2010 or newer model, with Intel's hardware support for Memory Management Unit (MMU) virtualization, including Extended Page Tables (EPT) and unrestricted mode. To see whether your machine supports this, run the following command in a terminal:
$ sysctl kern.hv_support kern.hv_support: 1
If your system does not satisfy these requirements, fear not—all is not lost. You can install Docker Toolbox (
https://docs.docker.com/toolbox/overview/), which uses Oracle VirtualBox instead of HyperKit. It isn't as good, but it is better than nothing.
