How to read DTEX file format in Nuke?

I'd like to add Pixar RenderManProServer 21.5 library's components for The Foundry Nuke on a Mac. These components are crucial for reading in DTEX format (for deep compositing). Foundry's User Guide tells me that I need to create an XML environment.plist file and place it in .MacOSX directory.

You can see it here.

But it doesn't work.

<?xml version="1.0" encoding="UTF-8"?>
<plist version="1.0">
    <dict>
        <key>DYLD_LIBRARY_PATH</key> 
        <string>/Applications/Pixar/RenderManProServer-21.5/lib</string> 
        <key>RMANTREE</key>
        <string>/Applications/Pixar/RenderManProServer-21.5</string> 
    </dict>
</plist>

Is there any other way to install RenderMan library's components for Nuke on a Mac?

~/.MacOSX/environment.plist is no longer supported in macOS (since 10.8). So, you need to put some lines in a hidden file ~/.bash_profile using pico editor.

In Terminal execute a sudo command:

sudo pico .bash_profile

# you need an administrator password for sudo command

and then put these lines in .bash_profile file:

echo RenderManProServer environment variables are set...
export NUKE_TEMP_DIR=/var/tmp/nuke-u501/
export NUKE_PATH=/Users/swift/.nuke
export RMANTREE=/Applications/Pixar/RenderManProServer-21.5/
export RMSTREE=/Applications/Pixar/RenderManProServer-21.5/
export DYLD_LIBRARY_PATH=/Applications/Pixar/RenderManProServer-21.5/lib/
export RMANFB=it
export PATH=$PATH:$RMANTREE/bin:$RMSTREE/bin/it.app/Contents/MacOS:$RMSTREE/bin/slim.app/Contents/MacOS

Do not forget to save this file pressing ctrl+o and exit pico editor pressing ctrl+x.
