Symbiote: Free up Mac disk space by symlinking files to an external drive

- **Symbiote** is a macOS utility that helps free up internal disk space by moving files to an external drive and replacing them with "symlinks" (symbolic links — lightweight pointers that trick apps into thinking the files are still in their original location). - **Why it matters**: Modern Macs often have fixed, non-expandable storage (e.g., 256GB or 512GB SSDs), and cloud storage isn't always suitable for large, local-only files like project folders, VMs, or media libraries. Manually creating symlinks is error-prone and tedious; Symbiote automates the process with a GUI. - The app is marketed as a one-time purchase with a free trial, positioning itself against subscription-based cloud services or Apple's own paid iCloud storage tiers.
