Hi TechyV,

After installing the mac os x I tried to run the x11 but it gave me the following message that it isn’t the part of the os any more and should be installed externally?

I would like to ask that if it is right or wrong did I miss anything?

Thanks for the solution.

An application has requested access to X11. Would you like to install X11 now?

X11 is no longer included with OS X. apple continues to support the development oX11 on OS x with the open source community. Clicking “Install” will take you to an Apple Knowledge Base Article which provides information about installing X11.

Hi,

You don’t need to install X11 onto your MAC operating system unless you have applications that need X11. If you’re running Unix App, you’ll definitely need the X11 to be installed on your MAC. In your situation, you just need to click on the install button. It does not harm your computer in any way. It’s very easy and effective application.

Thanks and regards,

Skarbos Jay.

The X11 application is originally included with OS X 10.5 Leopard until 10.7 Lion. This means if you install OS X 10.8 Mountain Lion or any higher version like OS X 10.13 High Sierra, the X11 application is no longer included. Even if the X11 application is no longer part of newer OS X versions, the X11 server and client libraries are still available from the XQuartz project.

The XQuartz project is an open-source attempt which Apple created as a community effort to further develop and support X11 on Mac. It was originally based on the X11 version included in OS X 10.5 Leopard.

It is designed to develop a version of the “X.Org X Window System” that runs on OS X which, together with supporting applications and libraries, forms the “X11.app” which ships with OS X 10.5 Leopard until 10.7 Lion. If you have OS X 10.5.x Leopard, you can download X11 2.6.3 which was released on July 20, 2011 and is the final release for OS X Leopard.

If you have OS X 10.6.3 Snow Leopard or higher, try downloading X11 2.7.11 released on October 29, 2016.
