Did you follow the troubleshooting guide? [Y/N]
Tried all relevant steps: clearing GPU cache, clearing full cache, disabling GPU acceleration (–disable-gpu, --in-process-gpu, --use-gl=swiftshader), deleting SingletonLock/SingletonCookie/SingletonSocket, and reinstalling. None resolved the issue.
Expected result
Obsidian opens normally.
Actual result
App crashes immediately on every launch. Obsidian Helper (GPU) subprocess aborts with EXC_BREAKPOINT (SIGTRAP) inside V8/Electron initialization. The main process then receives SIGKILL. No window ever appears.
Environment
Obsidian version: 1.12.7
Installer version: 1.12.7
Operating system: macOS 26.5.2 (25F84)
Hardware: MacBook Pro, Apple M4 (Mac16,1), 24 GB
Login status: N/A (app won’t launch)
Community plugins: obsidian-excalidraw-plugin, obsidian-kanban, dataview, advanced-canvas, obsidian-markmind
Additional information
The crash is in Obsidian Helper (GPU) — the Electron GPU subprocess — during V8 engine initialization (ElectronMain → v8::Object::SetNativeDataProperty → brk 0). This is a hard CHECK()/FATAL() abort in the Electron/V8 runtime. No stderr output is produced before the crash. The issue started after upgrading macOS from 26.4.1 to 26.5.2.
