The recent Java update (45) on Mac continues to be broken with respect to drag & drop but now adds a disabled GetFile function. JFileUpload no longer shows folders in the GetFile UI so it is now impossible to upload a file because one cannot navigate to the target file.

Pretty soon, all of our Mac users will be unable to upload by any means. Not drag and drop. Not GetFile.

Are you using QQLnF add-on for MacOSX? Could you try the online demo at:

Are you able to select a file/folder?

Could you try without QQLnF too:

For D&D, we don't think Apple plan to fix it, the only workaround is the frame over the browser:

Are you using MACOSX 10.8 or 10.9?

Safari 7 runs all plugins (Java, Flash) in internal sandbox now whatever trusted signature.
Another step from Apple to kill plugins silently.

There are 2 workarounds:
1 - Use FireFox
2 - Enable Unsafe mode on Safari 7, Preferences -> Security
