Note: Where the ~ symbol indicates the relevant Mac OS user's home directory path.

Solution 1: Copy MacLibs.zip from NetScaler firmware file and upload to /var/netscaler/gui/epa/scripts/mac.

Problem Cause

You will see the following error in epaplugin.log, which means NetScaler returns 403 forbidden when client attempts to download EPA library files. (The location of epaplugin.log is "~/Library/Application Support/Citrix/EPAPlugin")

Couldn't download library files from NS. Code =  403

This is because MacLibs.zip is missing in /var/netscaler/gui/epa/scripts/mac in NetScaler.
