Mac user here (15.3.1), have to jump through a few hoops, but I found this a while back when I also wanted to open .ps files: https://superuser.com/questions/1769824/is-there-a-macos-command-line-tool-for-converting-eps-or-ps-files-to-pdf (TLDR: home brew install ghostscript, then use ps2pdf)
Hope that helps, Henry. ######################################################################## To unsubscribe from the CCP4BB list, click the following link: https://www.jiscmail.ac.uk/cgi-bin/WA-JISC.exe?SUBED1=CCP4BB&A=1 This message was issued to members of www.jiscmail.ac.uk/CCP4BB, a mailing list hosted by www.jiscmail.ac.uk, terms & conditions are available at https://www.jiscmail.ac.uk/policyandsecurity/
