Mac internal storage is expensive ($200 for 256GB!). ExtBridge lets you move gigabytes of Apps (Xcode, Logic Pro), Media Libraries (4K Video, Photos), and Archives (Backups, VMs) to external SSDs without breaking system links. It creates system-level symbolic links automatically. Plug in your drive to run apps seamlessly at native speed; unplug to take them to go. Save money on your next Mac purchase by buying the base model and expanding with ExtBridge.
