Notes on Enabling Hermes Agent Computer Use on macOS — Seven Snags Around /Applications and TCC Permissions

As a follow-up to the selection notes I wrote earlier, I actually enabled the Hermes Agent v0.21.1 computer_use toolset on a real macOS Tahoe (26.6) machine. The docs make it look like a single hermes computer-use install command, but the cua-driver macOS installer hard-codes .app placement in /Applications, the Mac is a Jamf-managed device where I started without admin rights, and TCC binds permissions to the driver's own bundle identity. Those pieces combined to trip me up seven times. This article writes each snag down with symptoms, causes, actual log output, and the resolution, so the next person setting this up has something to grep for.
