PTViewer on Mac OS X

If you want to install ptviewer.jar (view 360° images) in /Applications, it won't start right. After you move it into /Applications, modify the permissions of the file: select the file, press CMD+I or select File->Get Info... from the menu bar:


Click on the lock (1) and enter the administrator's username and password. Usually that's you.
Next (2), set 'Everyone' to 'Read & Write' and close the window.

Now it works.

I made some photos of my office with my iPhone4, turning my desk chair 360 degrees and stitched them together on my iPhone with AutoStitch. Looks great in PTViewer!
