Zscaler Delivers Same-Day Support for macOS Tahoe and iOS 26

Zscaler is thrilled to offer full support for iOS 26 and macOS Tahoe. As of September 15th, Zscaler Client Connector (ZCC), Digital Experience (ZDX), and Data Loss Prevention (ZDLP) were validated for seamless compatibility, ensuring uninterrupted security performance and productivity for enterprises.

Zscaler delivers reliable, instant support for every Apple release by testing beta versions, resolving issues early, and engaging with customers via its Community. With this readiness, we empower businesses to stay secure and productive with every innovation Apple brings.

What Same Day Support Means — And Why Does It Matter?

Same Day support gives IT teams confidence to enable Apple OS upgrades immediately, with Zscaler components (ZCC, ZDX, and ZDLP) fully supported and tested for smooth, disruption-free performance. 

An enterprise customer with 75000+ MacBook computers shared: “Over the past few years, we’ve seen a tremendous improvement in new macOS support from Zscaler. The consistent support and transparent communication has been fantastic, and we look forward to a strong partnership moving forward.” 

How Zscaler Achieved Same-Day Readiness

Zscaler Product and Engineering performed months of rigorous beta testing through Apple’s AppleSeed for IT program. This included validating enterprise scenarios, reporting issues directly to Apple, and aligning with new OS functionality. Customer feedback through Customer Success teams and internal QA ensured reliability across hybrid and remote deployments. Our pillars for success included: 

• Continuous beta testing for each OS update, including release candidate, and GA builds.
• Early identification and reporting of OS-level and compatibility issues directly to Apple—proactively identifying issues and staying ahead of the curve.
• Thorough validation across diverse enterprise use cases including remote and hybrid deployments.
• Driving strong alignment with Apple and embracing new OS capabilities where relevant.

What Same-Day Support means for Zscaler Customers

For our customers, this achievement delivers peace of mind on several fronts. With immediate compatibility for ZCC (including ZDX & ZDLP) on both macOS Tahoe (ZCC v4.5.2, v4.5.1, v4.5, v4.3.1 LTS) and iOS 26 (ZCC v4.4, v4.3.5) enterprises gain: 

• Same-Day readiness: Upgrade seamlessly with confidence and no downtime
• Continuous protection: Security posture holds firm during OS transitions
• Agility for IT: Eliminate vendor wait times, emergency troubleshooting, and risky workarounds.
• Reliable experience: Consistent, high-performance access everywhere
• Ongoing testing and support for subsequent Apple releases
