MacOS includes a technology called Gatekeeper, that’s designed to ensure that only trusted software runs on your Mac. Gatekeeper in macOS Catalina requires an extra verification step called notarization, and NVivo software integrations such as SPSS need to be notarized.
As the SPSS integration is still being notarized by Apple, this button will not appear in NVivo – Mac for the time being as you will not be import SPSS data.
In the meantime you can export SPSS documents as a CSV file and import them into NVivo manually as a classification sheet.
NVivo – Mac supports importing classification sheets in Structured text file (.txt) format and CSV file (.csv) format with UTF8 encoding.
The SPSS integration will be enabled in NVivo – Mac once the notarization process has completed.
