Jettison 1.8 wears a new icon and is now a universal application, running natively on both Intel- and Apple Silicon-powered hardware on any system from Mavericks to Big Sur. It also includes a number of improvements and fixes to smooth the ejecting and remounting of external disks on all Macs.
Before your Mac goes to sleep, Jettison will now quit software that may prevent disks from being ejected, then relaunches whatever was running when the machine wakes back up. This includes Music, iTunes, Photos, Time Machine, Spotlight and their many helper processes. When your Mac wakes, Jettison will also do a better job of unlocking encrypted disks so they can be remounted, so the whole process is more reliable.
This release also fixes a conflict with Carbon Copy Cloner that prevented CCC from mounting disks to perform backups while the machine was asleep. And an issue that could cause Jettison not to correctly load its preferences after a system restart has been fixed, along with some problems with unmounting and remounting network server volumes.
