KB44312 - Pulse Desktop Client end users are unable to reach resources via proxy server after upgrading to macOS 10.15

This article describes an issue where Pulse Desktop Client end users are unable to reach resources through the tunnel via proxy server after upgrading to macOS 10.15.

After upgrading to macOS 10.15, Pulse Desktop Client end users are unable to reach resources through the tunnel via proxy server.  This does not impact resources that do not require the proxy server or end users who are running macOS 10.14 and below.

This issue occurs due to Apple has depreciated support for FTP and File based PAC file deployments in macOS 10.15 and above. [HTTP and HTTPS are the only supported URL schemes for PAC].

For more information, refer to Apple Developer Notes at https://developer.apple.com/documentation/macos_release_notes/macos_catalina_10_15_release_notes

Pulse Secure is actively working on the issue and plan on providing HTTP/HTTPS Proxy PAC based support for macOS 10.15 on Pulse Desktop Client 9.1.4 (Tentative for 15th January 2020).
