Jettison Free Download Latest Version for macOS. It is a full offline installer and standalone setup for macOS.
Jettison Overview
Jettison is a macOS utility developed by St. Clair Software that automates the process of ejecting and remounting external disks. It is particularly useful for Mac users who regularly work with USB drives, external hard disks, SD cards, network volumes, or other removable storage. Instead of manually ejecting connected drives before putting a Mac to sleep, Jettison can automatically eject supported disks when the Mac goes to sleep and remount them when it wakes. This helps reduce the risk of improperly disconnecting external storage and makes working with removable drives more convenient.
Jettison also provides menu bar controls for manually ejecting or mounting drives, along with settings that let users decide which disks should be handled automatically. Recent versions include improvements for disk remounting, NFS volumes, encrypted drives, and situations where system processes prevent a disk from being ejected properly. The current version, Jettison 1.9.6, runs natively on both Intel and Apple Silicon Macs and supports macOS 10.13 through macOS 26.5
