Second Life Viewer 2025.07 Apple Silicon Support

Build: 7.2.2.18475198968
Full Changelog: GitHub →

Hey everyone! We’re excited to share Second Life Viewer 2025.07, headlined by native Apple Silicon support and several key improvements to stability, voice, and UI performance.

New Features

• Apple Silicon Support — The viewer now ships as a Universal Binary, including both Intel and Apple Silicon builds. Expect smoother performance and faster rendering on M-series Macs.
• Nearby Tab Slider — A new slider makes it easier to manage visibility and sorting within the Nearby panel. (Thanks @secretfoxclaw!)
• Zoom to Object from Chat — Quickly focus your camera on an object mentioned in chat.

Quality of Life Improvements

• Performance Boosts on macOS:
  • Added support for Apple Silicon based systems.
  • Integrated CEF 139 for improved security and performance.
  • Added preloading of web content during login, reducing wait time when opening web-based floaters (e.g., Search, Marketplace).
• Voice & WebRTC Reliability:
  Improved device detection and recovery when unplugging/replugging microphones.
  • Fixed several rare WebRTC crash scenarios and added better voice cleanup and logging.
  • In world Voice indicator now properly reappears after tuning.
• Draw Distance Optimization: Viewer now automatically lowers draw distance when system memory is low, preventing sudden frame drops.
• Bandwidth Sanity Checks: Prevents invalid input and improves network stability during login/logout.
• Improved Logout Handling: Viewer now attempts to send a final logout message even under poor network conditions.
• SLURL Validation: Enhanced schema detection for more reliable link handling.
• Model Upload Warnings: Clearer notifications when physics libraries are missing.

Bug & Crash Fixes

• Fixed multiple crash issues in:
  • LLReflectionMapManager::update
  • LLJoint::findJoint
  • LLHUDEffect::render
  • LLWearableItemsList::ContextMenu
  • getDimensionsF32
• Restored Marketplace and Search navigation UI after regression.
• Fixed Shared Media on HUDs not loading properly.
• Resolved device index issues on macOS affecting audio input/output.
• Fixed voice cleanup and device update crash on reinitialization.
• Fixed build issues related to missing dependencies (nsis) and clang compiler warnings.
• Numerous stability updates from recent mac_arm branch reviews.

Developer Highlights

This release also includes several foundational updates aimed at improving build reliability, QA coverage, and cross-platform support:

• Continuous Integration Improvements: Added new runners to the QA workflow and integrated clang cleanup to remove unused variables.
• CMake Behavior Updates: Adjusted build targets to align with updated macOS deployment rules.
• Mac Arm Follow-Up Fixes: Reviewed and refined the mac_arm branch, ensuring parity between Intel and ARM architectures.
• Dullahan Browser Engine: Updated to CEF 139 for better compatibility with future Chromium-based features.
• General Code Health: Trimmed coroutine queues, improved logout handling, and tuned rendering logic for performance and maintainability.

New Contributors

Welcome and thank you to our new contributors this release!

• @secretfoxclaw — Nearby Tab Slider
• @fmartian — SLURL Schema Check Improvements
• @Dan-Linden — Core QA and Build Enhancements

Known Issues (macOS)

• MacOS X 11 and older will not run on this and future viewers, please use build 7.2.1.
• Pathfinding tools are not yet supported on Apple Silicon.
• Convex decomposition and mesh upload only work via Rosetta.
  • To enable: Right-click the Second Life Viewer app → Get Info → Check “Open using Rosetta.”
  • A fix for native Apple Silicon pathfinding and physics tools is planned for the next release.
• The viewer's disk image will display x86_64. It is in fact a Universal Binary.

Enjoy exploring this new Universal Viewer!
We’ll share benchmark numbers for Apple Silicon performance soon — early testing shows notable gains in frame rate and responsiveness.
