AsianEfficiency: 20+ Great Productivity Apps – including Default Folder X

Monday, March 19th, 2018

The folks over at AsianEfficiency have a new podcast episode where they recommend a number of great productivity apps – including Default Folder X, of course 🙂

Though I’m a bit biased on Default Folder X, they also endorse a number of other apps that I use regularly, including TextExpander, MindNode, Keyboard Maestro, BusyCal, Hazel, Twitterific, MarsEdit and BBEdit. Have a listen to the podcast or check the links at

Jettison 1.6 improves remounting and APFS support, adds AppleScript commands

Jettison 1.6

Jtsn iconBefore starting a reorganization and rewrite of Jettison’s internals, I figured I’d better officially release the myriad little changes that I’ve been trickling out to various folks as they’ve contacted me with issues.

Version 1.6 brings Jettison up-to-date with APFS (the new file system format released in High Sierra) as well as making its drive mounting / remounting procedure more robust. There are also a bunch of bug fixes and improvements in error checking and error reporting, and new AppleScript commands for ejecting, remounting and sleeping.

You can grab the update from the Jettison Release Page, as well as seeing a more complete list of changes there.

Known Issues

There are still a few issues with Jettison on High Sierra, primarily due to some flakiness on High Sierra’s part that I haven’t been able to pin down. If Jettison can’t eject a drive and tells you “try ejecting it in the Finder,” that means that macOS refused to eject the drive, won’t tell Jettison why, and there aren’t any files open on the volume that should logically keep it from being ejected. In that case, Jettison just throws up its hands and says “I give up!”

If you ask the bus driver to stop the bus and he just keeps on driving, what can you do? (Well, you could open the window and jump out of the speeding bus, but I doubt you want me to do that with your external drives…)

So I’m continuing to chase down that issue, as well as a rare one where the machine continually cycles between sleep and wake states every few seconds, resulting in hundreds of “External disks ejected” notifications from Jettison while the machine was supposed to be sleeping. This situation is rare and I’ve been unable to reproduce it here, making it a tough one to figure out. If it’s happening to you, please let me know at

App Tamer 2.3.5: Performance fixes and little tweaks

Friday, March 2nd, 2018

Version 2.3.5 of App Tamer is available, bringing several improvements and fixes on the performance side, as well as showing you how much CPU time it has saved.

It gives a cumulative “CPU-hours saved,” where a CPU-hour is the amount of computing a single processor core can do in an hour when running at 100%. So if it says it’s saved 8.8 CPU-hours, as shown in the image on the right, that means one CPU would have been running full tilt for an additional 8.8 hours if I hadn’t been using App Tamer. Which means the fans in my MacBook Pro would have driven me crazy today without App Tamer 🙂

Other changes include fixing a memory leak that would cause App Tamer to gradually use more and more RAM if left running for long periods of time, fixing some UI glitches and improving VoiceOver support.

Grab a copy of App Tamer 2.3.5 from the App Tamer Release page, or by selecting “Check for Updates” from its menu if you’re already running it.
