Calibre 0.8.16 crashes on launch on Mac OS X 10.6.8

[Neil P. Quinn]

I recently downloaded Calibre 0.8.16 for Mac OS X, opened the .dmg, and installed the application by dragging it to the Applications folder. However, when I try to open it, the icon appears on the dock, bounces for a few seconds, and then disappears. Nothing further results. I have tried the whole procedure, beginning with the download and clean installation, twice with no variation.

That error indicates that one of the system libraries on your machine si out
of date. It is missing the function _FSMoveObjectToTrashSync. You should
contact Apple for support, they will tell you how to update the library on
your system.
