What's Wrong?

Claude wrote this for me. I tried opening Claude app but it didn't open, even though my memory and CPU were alright, so I tried using Calude code to troubleshoot, he didn't success and gave me this text to report to you

Title: Claude desktop app fails to launch on macOS 26.5 (25F71)

Body:

macOS version: 26.5 (Build 25F71)
Claude version: 1.7196.3

Issue:
The Claude desktop app hangs at startup and never opens. The process starts
but is stuck at _dyld_start indefinitely with only 32KB RSS and never spawns
any Electron helper processes.
Root cause identified:
Three frameworks that the bundled Electron Framework links against have been
removed in macOS 26:

• Carbon.framework
• Quartz.framework
• QuickLookUI.framework

These return MISSING when checked on macOS 26.5. dyld cannot resolve them,
causing a permanent hang at process initialization.

Steps to reproduce:

1. Install Claude 1.7196.3 on macOS 26.5 (25F71)
2. Launch Claude.app
3. Process starts but never initializes — stuck at _dyld_start

Workaround: Using claude.ai in browser.

Fix needed: Update bundled Electron to a version that doesn't depend on
removed macOS 26 frameworks.

What Should Happen?

The Claude app should open
