Apple Aperture and Nik Plugins.
There's weird bug that appears when sending photographs from Apple Aperture over to a Nik Collection plug-in for editing. When you come back to Aperture, the image is either stuck or invisible (you get only grey in the viewer). It seems this only happens on Mac OS X 10.9 Mavericks.
I've tried repairing and rebuilding the Aperture Library but that didn't fix the issue. Only quitting and restarting Aperture solved the problem, which isn't really a solution.
A fellow photographer posted a workaround on Aperture Expert that, while not a fix, is much better than restarting.
Tim Stringer recently announced a new venture called Learn Omnifocus. He describes it as "a site dedicated to supporting people in living fulfilling, productive lives with some help from OmniFocus for Mac & iOS".
You can sign up now to be notified when the site officially launches. I've done it and can't wait to see what he has in store for us.
I've written about Tim before when I shared my takeouts from the OmniFocus Setup presentations. He spoke about how to setup your OmniFocus library based on the main areas of focus in your life. I still keep my library organised that way.
