A couple of things are unclear in your post.
1. You say you installed ImageMagick. Does it work (outside of IDL)? Can you convert (from the MacOS terminal prompt) a postscript file to PDF
convert idl.ps idl.pdf
2. IDL simply spawns a call to ImageMagick to convert the postscript file so there shouldn't be any special steps needed to "link" IDL. But you also mention a problem with the created postscript file, which would have nothing to do with ImageMagick. Are you able to run your program and successfully create a postscript plot? --Wayne

I went through the various posts on this (see e.g: http://www.idlcoyote.com/cg_tips/findimonmac.php) but it gets a bit involved...is there a clear sequence of steps to link IDL to the right place? I seem to understand the problem is with the "convert" executable. I tried to download the last version of ImageMagick and it got unpacked in the Applications/ directory but nothing changes. Note that I tried to use the older PS_START and PS_END commands, everything runs fine but the generates ps file is blank.

I obviously have CGFIXPS in the Coyote library, but the problem seem to be in the following lines (as it seems to have been noted here: https://github.com/idl-coyote/coyote/issues/11). Any idea on the best fix for this issue?
