Introduction to CiscoJabberMac-14.3.1.308554.pkg

This software package delivers Cisco Jabber 14.3.1 for macOS, the enterprise-grade unified communications client optimized for Apple Silicon architecture and hybrid collaboration environments. Released in Q1 2025, it introduces quantum-resistant cryptography and enhanced Webex Messaging interoperability while maintaining backward compatibility with CUCM 14.x infrastructure.

The installer bundle (build 14.3.1.308554) provides native 64-bit support for:

  • macOS Sonoma 14.0+ with Metal 3 GPU acceleration
  • Apple M1/M2/M3 Pro/Max/Ultra chipsets
  • CUCM clusters upgraded to TLS 1.3 with post-quantum algorithms

Designed for financial institutions and healthcare organizations requiring HIPAA-compliant messaging, this version implements FIPS 140-3 validated encryption modules for end-to-end data protection.
