NX 8 Release Notes
Mac OS X Support 
Hardware and installation requirements 
Hardware and operating system requirements 
The release of NX 8.0 on Mac OS X supports Apple Mac 64-bit Intel based systems. These include the MacBook Pro, iMac and Mac Pro systems. All available graphics subsystems are supported.
The minimum version of Mac OS X required to run NX 8.0 is Version 10.6.6. Later versions, including Snow Leopard (Version 10.6.6 or higher) are also supported.
Installation of NX on Mac OS X is supported only on an HFS+ file system. However, NX part files and other data files may be stored and retrieved from an NFS file system.
X11/Motif requirements 
NX 8 on Mac OS X utilizes X11/Motif to support its graphical user interface. A third party Motif package called OpenMotif, and the X11 application bundled with Mac OS X 10.6 Snow Leopard, are required. X11 is installed by default, and thus should be available unless you have disabled it.
Updates to X11 may be provided by Apple and distributed via the Software Update mechanism. We support the version of X11 bundled with each update. X11 releases obtained from http://xquartz.macosforge.org/trac/wiki are not supported and may cause operational anomalies. 
OpenMotif must be installed prior to installing NX. Obtain the OpenMotif toolkit, openmotifcompat-2.1.32_IST.macosx10.5.dmg, from the following website:
http://www.ist-inc.com/DOWNLOADS/motif_download.html
The X11 application must be running while using NX. The X11 application will be started when NX or any other X-based application is invoked.
Installation 
Installation must be performed from an account with administrator privileges and must be performed on a Mac since it uses the Mac OS X Installer application.
To install, double-click the nx.8.*.mpkg file and follow the instructions presented in the installation dialog box.
 
Note	If the .mpkg file has a .tar.Z or .zip extension, then it is compressed. You must first double-click it to uncompress it and create the .mpkg file. 	 
Optionally install the online documentation by double-clicking the ugdoc.8.*.pkg file and following the instructions.
Optionally install the license server by double-clicking the ugslicensing.*.pkg file and following the instructions. The license server will be needed if you are installing NX on a system, such as a laptop, that is not connected to a network.
