Problem connecting Ghostscript with MacOS 10.15 Catalina

Hi. I had a problem connecting Ghostscript 8.71 with MacOS 10.15 Catalina because it is not 64-bit capable.
Artifex was removing some older Print drivers that were built into Ghostscript following the updated 9.04 version. Now, I saw that version 9.20 removed an operation that included only gdevadmp and all of its supporting files, unlike what 9.05 had (appledmp, iwhi, and iwlo, and iwlq moved to “devices” folder).
The thing is, can someone help me how to code this properly to make it work with 9.20 64-bit as it seems my codes are not properly set up?
