System-level GPU crashes when using Premiere Pro on macOS 15.5 (Sequoia) with an M3 Max MacBook Pro.

Heads-up: M3 Max Crashes with Premiere Pro under macOS 15.5 (Sequoia)

I've confirmed system-level GPU crashes when using Premiere Pro on macOS 15.5 (Sequoia) with an M3 Max MacBook Pro.

During scrubbing, timeline exports, or Metal stress tests, my system flashes red and reboots without warning or error dialog.

Here’s what I tested (June 17–19):
- ✅ CPU and memory stress tests = no crash
- ✅ Same drives/projects on Intel iMac = stable
- ❌ M3 Max crashes under GPU load only (WindowServer, AGXMetalG15X-M1, QuartzCore in logs)

THIS ISN’T A PREMIERE BUG — the fault appears to lie in macOS Sequoia’s Metal/QuartzCore stack on Apple Silicon (M2/M3).

I’ve built a ZIP package with full crash logs, diagnostic scripts, and test configs. If others are experiencing this, I encourage comparing logs or referencing my report for escalation.

Premiere Pro: 25.4 (Beta, Build 54)
Chip: Apple M3 Max – 128GB RAM – 4TB internal
Drives: G-Raid, WD Black (ACSIS enclosure, TEAMGROUP 8TB (ACASIS enclosures)
Config: Tested both via Thunderbolt hubs and direct USB-C ports
