Hi I want to upgrade my old 2000 Imac and my Ibook to Panther but I am concerned that if I do upgrade I will loose all my opensource software that I have installed in the unix shell, for example Pine, Tintin, Openoffice, etc etc. Will Panther destroy these programs? Will I have to reinstall each unix program? Any help in this would be appeciated. Thank you Mike __________________________________ Do you Yahoo!? New Yahoo!
