If you do not see changed libraries in the resource browser after copying files by using Explorer/Finder, you can try to "Refresh Libraries" in the Resource Manager. That should avoid you to have to shutdown and re-start VW.

No, older versions than VW 2018 will never be supported for macOS 10.14 (Mojave)

In 2019 you can revert to previous SP with help of the Updater. See that post:

I can only support the recommendation that GOTO should be avoided. Also I think that describing about how to use GOTO should not be in the documentation. New users should not even think about following that path. (Luckily at university, we had to use a Fortran 77 compiler that supported structural programming. However I know GOTOs from a few BASIC versions.)

For your information: the German VW 2018 SP5 uses again the regular SDK.

Try to use VW 2018 SP4 again for now.

Yes, that is why I wrote "around a decade": from ca. 2007 to ca. 2019.

Or you can compare it with the situation with Carbon. For a 32 bit application, it is still available. For a 64 bit application, it was never available: Cocoa must be used. As 32 bit applications are still supported in Mojave, that makes a conversion period of around a decade.

Are there more .dmp files in your user folder? (According to your signature, you use Windows, don't you?)

You should probably ask ComputerWorks.

You can check the "Vectorworks Operating System Compatibility List" for what could be considered "typical" support of operation systems. (Windows is far more stable, therefore supported back to Windows 7).

The aforementioned article reads at the end: "In addition to the release of Vectorworks 2019 SP1, we are also working on a macOS Mojave service pack for Vectorworks 2018. We hope to have it available later this fall." I suppose that this quote was meant by @Neil Barman

Ah, OK, file right issues.

Yes, I had it once. Installing again (in another folder) had solved it for me, as the new installation did have all the correct files.

As nobody has answered you yet, I will give it a try. - have you enough free space on the destination volume? - perhaps you should try to repair the installation to VW 2019 SP0 and then try again to update. For going back to VW 2019 SP0 see the following post:
