Notes

Existing reports (#32225, #23830, #26646) cover macOS 26.x. Filing this to track the same class of hang on macOS 15 Sequoia, which does not appear to be covered.

VM bundle (~/Library/Application Support/Claude/vm_bundles, 973 MB) and claude-code-vm (237 MB) cache cleared as a workaround; will report back if the hang reproduces on a fresh VM download.

Repro

  1. Launch Claude Desktop on macOS 15.6.1
  2. Open the Cowork tab
  3. App becomes unresponsive (spinning wheel, no input accepted)

Expected

Cowork tab loads and remains responsive.
