Pdf from new Mac Rhino in Beta Catalina

Running Catalina…from the print menu…attempting to save as a pdf … get Error while printing (did this several times). Also tried Save as adobe pdf–nothing happens, not even a error message. Did find a work around–open in preview and then export to pdf. Thoughts?

@dan FYI

Hi @debbooth-

Thanks for reporting this.

Unfortunately, I’m not able to reproduce this on my Mac. Here is what I’m doing:

  1. Launch Rhino 6 for Mac (6.18.19266.13352) running on macOS Catalina 10.15 Beta (19A573a).
  2. Start a new modeling window.
  3. Run the Box command and draw a box near the origin.
  4. Navigated to File > Print….
  5. From the Print dialog, in the lower left-hand PDF drop-down, selected Save as PDF
  6. In the Save sheet, I changed the title to Test.pdf and set the Where: to my Desktop and clicked Save.

Test.pdf appears on my Desktop and shows a box.

What are we doing differently?


Hi Dan,
Basically I did the same.

  1. launch Rhino 6 for Mac running Catalina 10.15
  2. tried with a file I was working on
  3. Navigated to file print and same
  4. print dialog–drop down save as pdf–get that error message.
  5. Also did what you did opened a new window, tried the same, same error message.

The error while printing come up over the preparing to save window almost immediately each time.
Also tried save as Adobe PDF – nothing happens, no error message and no file
Also tried save as postscript–error message

Hi Dan,

I downloaded and installed again–and everything seems to be working now. Perhaps I had a corrupt file.
Thanks for being so quick with the response and I really like this mac version–great improvement! Wow.

Hi–its me again. The problem has returned. It worked fine one time after I reinstalled but since then…same problem, same error message Error while printing. As I said, I can work around it by going to preview and exporting as a pdf–just adds another step.

Hi @debbooth I am having the exact same problem. Were you able to find the source of the problem or a solution ??

You’re probably NOT running an old Beta Catalina.
Please run the SystemInfo command in Rhino V6 and post the results.

Correct, my Catalina is not Beta. What can I do?

Mine seems to be running fine now making those PDFs. I was so used to opening in preview and then making them, I forgot to check. I am running a Beta Catalina…not an old one–but current version 10.15.3

Ok, spoke too soon. It still fails. So clearly there is a problem. It could be the Beta Catalina-- but for now I will do the work around. It’s a pain, adds a step but unless someone has a better solution?
