Hi all just joined the list because I want to return to some csound stuff after a long absence. but I seem to have fallen at the first hurdle! I am trying to install on a Mac G5 with OSX 10.4.11 and the Csound5.08-OSX10.4-PPC(3).tar.gz reports an error when unzipping. The folder with the installers appears and the installer pretends to work but nothing gets installed. I have tried a number of unzippers inc. stuffit NutCase Gzip and none work. - Also tried earlier versions of csound 5 with the same results anyone know what is going on??
