Shared Runners let you start a runner with --share so your entire workspace can spawn agents on your machine from ampcode.com, useful for GPUs, specialized hardware, or network-specific dev boxes. The macOS app now runs as a runner automatically, eliminating the need for a terminal command; add folders in Runner settings and pick "This Mac" when starting threads. A new "Keep This Mac Awake" option prevents sleep while the runner is active and plugged in, so threads can run after you step away. Shared runners receive workspace and project secrets but never personal ones, and workspace admins can disable sharing in Member Settings.
