Works perfectly on Yosemite - I use this software everyday.

When a piece of software becomes indispensable I try to write a positive review.

Dropzone 3 is amazing. I have to share many screenshots. The joy I get when I can drag a screencapture to dropzone for automatic upload to IMGUR is immeasurable. That alone saves so much time daily. I set up a drag and drop for my Amazon S3. Whenever I want to share a large file > 30 MB, I drag it to dropzone and it’s in the cloud and there is a link on my clipboard. For the money you will not be dissapointed.
