Aperture crop tool stopped working I just got back from a hike, slurped the pix off my camera to my Mac, and can no longer crop my pix:

The usual shortcut C leaves the cursor as an arrow, not the crossed carpenter's squares.

If I add a crop brick to the adjustments pane, entering numbers there makes no difference.

I can make other adjustments -- e.g. levels -- so it's not like I've got it in quick preview mode.


Mac Pro 2012 24 GB
macOX Yosemite 10.10.5
Aperture 3.6
Reinstall of aperture (actually, copied the app from another computer) fixed the problem.  

This is a windows-esque heavy handed solution that lacks elegance.
