According to this link, QGIS 3.10 and newer can create GeospatialPDFs. However, when I go to export through layout view, the box is greyed out. What am I doing wrong?
Edit: As someone below points out, this question has a workaround for PCs but Macs are out of luck. See: Export geospatial PDF from QGIS on Mac
More details: When I go to export PDF through the layout view, the box for Create GeospatialPDF (GeoPDF) is greyed out with the message "GeoPDF creation requires GDAl version 3.0 or later." I have tried manually updating my GDAL to the latest (3.1.2) and upgraded my QGIS from 3.10 to 3.14. The message persists. From past StackExchange messages, I see that there are a number of workarounds from before QGIS supported GeospatialPDFs, but I'm hoping to get this particular feature of the PDF export function to work. I'm using Mac OSX 10.14.6.
