Testers with a Macintosh are needed for for Dali/CE viewer. Before the CE-DALI viewer can be released I need to know whether it is running with early Macintosh OS-X versions and whether it is running on recent Macintosh with Intel. Please click one of the PDB IDs in http://www.charite.de/bioinf/strap/ce_dali.html A 3D alignment and a 3D superposition should appear. The help text should contain graphical elements.
