INSTALL.MacOS

In MacOS you need install macports and then:
#sudo port sync
#sudo port install ImageMagick

In pstoricohddst-gdi file uncomment (remove heading "#") three lines in the beginning of file, after line:
"#Next four lines must be uncommented in MacOS".
And comment (add "#" to begin of the line) three lines after line:
"# Next four lines must be uncommented in Linux"

Then we should disble strict sandbox for cups. Otherwise it have no access to Ghostscript and other necessary utilities.
DO NOT RUN THIS ON A MACHINE RUNNING MAC OS 10.9 OR BELOW
    sudo sh -c 'echo "Sandboxing Relaxed" >> /etc/cups/cups-files.conf'
    sudo launchctl stop org.cups.cupsd
I'd tested this on High Sierra with Sandboxing Relaxed in the begining of cups-files.conf

Then look INSTALL instructions.

P.S. inotify-wait does not exist for mac - it is not needed by script, it is optional. Do not worry about it.
P.P.S. After years with linux I finally switch to Mac. I've made that decission because thik that I was
too tired fighting endless Linux bugs - I'm talking about desktops. And face another tons here... :)
