Rhino 6.17 for Mac import/export issues

I am running Rhino 6.17.19236.01022 for Mac. Latest one as of this date.
In the Import box, all files except .3dm and .gh are greyed out even with ‘all readable files’ selected in options.
I cannot even select a .dwg, .dxf, .obj, .skp file for import.
This was not the case up until the previous update.
Has the importing workflow changed in the current version?

Hi @neeljain28-

I cannot reproduce that here in 6.17.19236.01022. Are you running the macOS Catalina Beta by any chance?

I am using macOS Mojave 10.14.6
Also, I have noticed this issue only occurs in the evaluation version, when I log in using my regular license than I am able to import/ export as usual.

Hi - that sounds like the evaluation version has expired. When that happens, all plug-ins, including import and export, will be disabled.
