Overall, the SPSS for Mac and Catalina (macOS 10.15) are compatible however, there are a few issues to be aware of when upgrading to Catalina or installing SPSS Statistics on Catalina for the first time.

Issue with Opening Files: Due to tighter security in Catalina, all versions of SPSS will be blocked from accessing the following folders: Documents, Downloads, Desktop and connected external disks. 

• Workaround: You can move your working files to another folder. Watch this video to learn how.

Issue with Installation: Installing SPSS for the first time on Catalina may result in an error message that the installer cannot be verified. Catalina requires all downloaded software to be notarized by Apple. IBM has started the notarization process and expect it to be completed soon.

• Workaround: You can run a command to un-quarantine the SPSS Stats installer which will allow it to run properly. Watch this video to learn how.
