How to choose Passive Mode on Mac version? There is no „Server“- Button in the FTP accession menu. (For the German version which I use, see attached image).
I don't have a Mac and so don't use UltraEdit for Mac, but I found with a quick www search Change proxy settings in Network preferences on Mac. It looks like there is per interface the proxy setting Use passive FTP mode for file transfers which all FTP clients on Mac have to read and establish the FTP connections according to this setting.
