I just installed a newly downloaded the Taskpaper 3 preview, and installed and launched it. I can add text in the edit window, but there’s a modal dialog with spinner which hangs there. I can’t quit the app, nor close preferences. This is on 10.10.5.
Two possibly non-standard things about my install:
- user who did install does not have admin privileges
- Taskpaper is installed in ~/Applications instead of /Applications
