Hi @colinwgrant,
I am now able to download and install the public release of macOS Mojave. I am aware of two issues related to Mojave with AutoCAD and they are OS issues.
The first is related to a file read-only message when trying to open a file from Gallery view of Column view within Finder or from the Select file dialog within AutoCAD. The work around is to change to list or icon view in finder or the Select file dialog.
The second known issue is that a message may appear that indicates that AutoCAD would like access to your contacts/calendar on macOS Mojave. The workaround is to click either Don't allow or OK as both selections will work because AutoCAD is NOT actually trying to gain access. This is an OS message that does not apply.
Please select the Accept as Solution button if my post solves your issue or answers your question.
