How to use global filter on macOS

[trinhtranduc]

Hi,

I’m looking for a way to intercept my filter globally on macOS. Currently it works when I modify the PPD file for a particular printer.

However, I don’t want to modify the PPD. I believe I need to modify the CUPS MIME configuration instead, but I can’t insert my filter because those files are under /usr/share/cups/mime/ and are protected by SIP.

My question: is it possible to provide an additional MIME mapping or configuration that CUPS will recognize so I can chain my filter globally without editing the system files protected by SIP?

You can also place .types and .convs files in /private/etc/cups.
