Hi Anh,
I have received some help from our Techincal Support team. In short, you need to use Universal Naming Convention path in order to have the link works on both Windows and Mac. Allow me to explain in detail how it looks like:
If you have a common file server, which let's name it "COMMON", it is available through the internal network of your office. Therefore, the computer where you have this file server, must have a name. Let's call this computer "common-pc-w10".
Now, when you are in ARCHICAD, when you locate the file server, on Windows, use this: \\common-pc-w10\exampledrawing.pdf, while on macOS, use this: //common-pc-w10/exampledrawing.pdf
In this case, ARCHICAD can always find the proper path to the file server, no matter which platform you are working on.
I hope that this information will help you on this matter. If you have any further questions, feel free to reach out to me again!
Thank you very much!
Best regards,
Minh
