Jettison 1 7 2
Version 1.7.3 of Jettison is now available. It fixes a problem when running on Apple’s latest Catalina beta where it would try to eject Catalina’s new system data volume if the system was running from an external drive.
In addition, Jettison 1.7.3 also improves its error reporting and handling, allowing you to quit applications that are preventing a disk from being ejected. This release also addresses an occasional problem with disk images not getting completely cleaned up after being ejected.

At 36,000 feet (11,000 m) and Mach 1.7 (1,815 km/h), the heating conditions on the shock cone were similar to those at sea level and 650 knots (1,200 km/h) indicated airspeed, but if the speed was increased to Mach 2.0 (2,136 km/h) at 36,000 feet (11,000 m), the shock cone was exposed to higher temperatures than those at Mach 1.7. Update your bedding ensemble with the Nautica jettison grey quilt set. The serene quilt and coordinating shams feature a relaxed grey, white and blue stripe design. The stylish quilt reverses to a white anchor motif on a blue ground that also trims the edges of both the quilt and shams. Prewashed for added softness, this all-cotton quilt set is.

Well, Jettison 1.8 didn’t go quite as planned. It adopted a different system API to get power notifications so that it could better handle “dark wake” events, where macOS wakes up briefly to perform backups and network maintenance while it’s sleeping. While the dark wake stuff all worked as expected, it ended up causing issues with some external drives not getting ejected before sleep because sleep notifications were delivered slightly later in the going-to-sleep sequence. It didn’t make a difference on test machines here or with our beta testers, but impacted some users out in the real world once version 1.8 was released. If you’re one of those folks, I’m sorry for the trouble 🙁
Version 1.8.1 was released today, and takes a hybrid approach, using both the old and new API’s to ensure that it gets sleep notifications as early as possible. This restores the reliability of Jettison’s eject-on-sleep capabilities.

This release also allows you to turn off the feature introduced in version 1.8 that quits Music, iTunes and Photos before sleep (to allow ejection of external media containing music and photo libraries). Apparently iTunes doesn’t correctly return to the same location in audiobooks when Jettison relaunches it after waking up, which can be really annoying. So you can disable the feature by using this command in Terminal:
