Install Putty On Mac Catalina

Posted on by admin

We already have a tutorial on how to install macOS Catalina on Linux. A simple tutorial on how set up a macOS VM in QEMU, accelerated by KVM. This is basically the same tutorial but everything runs, near native with X11 forwarding, in Docker.

This is not a Docker tutorial, but let’s have a quick look at how to install it on Arch linux ( more info for Docker on Arch here ). For other distros as well as how to install Docker on macOS and Windows, check out the official installation guide here.

1. Open up the terminal and type sudo pacman -S docker

2. Once Docker is installed type in sudo systemctl start docker and sudo systemctl enable docker

  • CentOS/Rhel/Fedora: sudo yum install libvirt qemu-kvm -y

3. Now, run:
sudo systemctl enable libvirtd.service
sudo systemctl enable virtlogd.service
sudo modprobe kvm

4. Reboot your machine

5. Now pull the image with docker pull sickcodes/docker-osx

6. Run docker run --privileged -e 'DISPLAY=${DISPLAY:-:0.0}' -v /tmp/.X11-unix:/tmp/.X11-unix sickcodes/docker-osx

7. Boot from macOS Base System

8. Now the macOS installer will load. Select Disk Utility and format the largest disk in the list.

9. Exit Disk Utility and and select Reinstall macOS

Catalina

10. On restart, select macOS to continue the installation.
