X11 for Mac OS X updated. This release contains Xquartz-1.5.3-apple14. Download X11-2.4.0.dmg, and open it to install with Leopard's Installer. As of 2.2.0, you do not need to have Leopard's X11 package installed (but it is alright if you do). No longer built -with-old-mac-fonts in order to prevent linking against CoreFoundation.

Catalina is the first version of macOS to adopt wholesale the relatively new Apple File System (APFS), which is optimized for the flash storage used in recent Macs.
Sosumi is a snap package based on macOS-Simple-KVM that makes it easy to download and install macOS in a virtual machine (is comes bundled with qemu-virgil, which includes virtio-vga, a paravirtual 3D graphics driver). It does not ship with macOS, but downloads an installer image for macOS Catalina.

Get X11 Forwarding In macOS High Sierra

I needed to forward X11 output from one of my Linux servers recently to run virt-manager (manager for virtual machines in KVM), and because it’s been a while I had to download and install X11 server again.

As some of you know, Xorg server is no longer shipped/installed with macOS by default. So you have to download it from XQuartz page: https://www.xquartz.org/releases/index.html. Usually you do it, install it and that’s it – no additional steps are needed.

But things are slightly different for the macOS High Sierra, apparently.

The latest release hasn’t been updated since 2016 which I believe is before High Sierra – which explains why things don’t “just work” anymore. Fear not though – I tracked the issue down and it’s explained below.

UPDATE 03/2019: MacOS Mojave works just great, you may skip Step 3 in the procedure below.

Steps to get X11 Forwarding in macOS High Sierra

Download and install the latest release from xquartz.org website
Start XQuartz
IMPORTANT: verify xauth locationSSH configuration file /etc/ssh/ssh_config might contain path to xauth tool, which may be incorrect depending on your OSX/MacOS version. Here’s how to check:

if this returns nothing, you can skip to Step 4 below. If this gives you an output, compare it to the path from the next command:

If the locations differ, update the /etc/ssh/ssh_config file:

X11 Mac Os Catalina Update

Connect to remote server using -X option which does X11 forwarding for SSH:[email protected]:~ $ ssh -X centos.unixtutorial.or
Check the DISPLAY variable, it should now be set correctly:

That’s it for today!
