csshX not working on Monterey?
There is a Simple solution: All you have to do is edit the file: /usr/local/bin/csshX And Replace #!/usr/bin/perl with #!/usr/bin/perl5.18 The issue is that csshX does not work with later versions of Perl. macOS Monterey has Perl 5.30 as the default when you call Perl on your Shebang line. But you can invoke 5.18, and your cluster ssh terminal will work fine. Enjoy :)
