What's Wrong?

Claude Desktop fails to launch — EPERM on git-worktrees.json, macOS auto-applies com.apple.provenance attribute to ~/Library/Application Support/Claude blocking all writes

What Should Happen?

Claude Desktop should launch successfully and be able to write to ~/Library/Application Support/Claude without being blocked by the com.apple.provenance attribute that macOS 26 Tahoe beta automatically applies to the folder.

Steps to Reproduce

1. Install Claude Desktop 1.1.4088 on macOS 26.5 Tahoe beta (Build 25F71) on MacBook Air M4 2. Move Claude.app to /Applications 3. Launch Claude Desktop 4. App fails with "Claude Desktop failed to launch" 5. Running /Applications/Claude.app/Contents/MacOS/Claude in Terminal shows EPERM errors on ~/Library/Application Support/Claude/git-worktrees.json 6. Checking the folder with xattr -l reveals com.apple.provenance attribute applied automatically by macOS — removing it with xattr -rd has no effect as the system reapplies it on every launch 7. Granting Full Disk Access in System Settings → Privacy & Security does not resolve the issue
