A user asked me about possible problems with our TRAMO/SEATS and X13 addons under recent OSX versions. He sent me this link: https://support.apple.com/it-it/HT208436 If my understanding is correct, newer OSX versions will not run 32-bit programs. Does this affect us? ------------------------------------------------------- Riccardo (Jack) Lucchetti Dipartimento di Scienze Economiche e Sociali (DiSES) Università Politecnica delle Marche (formerly known as Università di Ancona) r.lucchetti(a)univpm.it http://www2.econ.univpm.it/servizi/hpp/lucchetti -------------------------------------------------------
