Installing the optional Apple X11 package on Mac OS X

Graphical displays in IDL and ENVI for Mac OS X requires Apple X11, which is an optionally installed package available on the Mac OS X operating system Install disk.

If you did not install the Apple X11 optional application package during the installation of your current operating system, it is possible to install just this package using the Optional Installs package installer that is included on the Mac OS X installation disk. Using this installer, it is not necessary to overwrite or reinstall the Mac OS X operating system.

This article discusses how to install Apple X11 via the Optional Installs package installer. The procedure is based on the installer CD for Mac OS X 10.4. The actual process for installing the Apple X11 application may be different for other versions of Mac OS X.Discussion:
