iMac 18,3 – macOS Tahoe 26.6.2 Wi-Fi + Audio Fix (English, CLI)

Status: September 26, 2026 – macOS Tahoe 26.6.2 (build 25G83), iMac 27" 2017 (iMac18,3), OCLP 2.5.1 Correct KDK: KDK_26.6.2_25G83.kdk (exact match, https://github.com/dortania/KdkSupportPkg/releases/tag/25G83)

All steps below are copy-paste for zsh. GUI is only needed once: MyKextInstaller → Install Kext → allow in System Settings.

0. Preflight – exact current state

Architecture (Rust Rewrite)

1. Architectural Goals

Strong isolation of protocol handling, domain logic, persistence, and delivery.
Trait-based adapters for storage, queue, media processing, auth providers.
Predictable performance through bounded queues + backpressure.
Minimal unsafe Rust (only in well-reviewed media bindings layer if required).
Observability built-in (tracing spans at boundaries).

2. High-Level Component Map

GoToSocial Environment Variables

GoToSocial uses environment variables with the GTS_ prefix. Any command-line flag can be converted to an environment variable by:

Adding the GTS_ prefix
Converting hyphens to underscores
Converting to uppercase

General Configuration

GTS_LOG_LEVEL - Log level (trace, debug, info, warn, error, fatal)
GTS_LOG_TIMESTAMP_FORMAT - Timestamp format for logs

🙋‍♂️ user:

Ich möchte im finder.app per Rechtsklick auf eine Videodatei die Option haben, ein bestimmtes ffmpeg command auszuführen. wie gehe ich da vor?
