If you need to use SPSS, do not upgrade to Sonoma at this time.
We have been informed by IBM, our SPSS vendor, that the new Mac Sonoma operating system (macOS 14.0) is not currently compatible with any version of SPSS.
If you need to use SPSS, then we strongly recommend that you do not upgrade to Sonoma at this time.
We will advise again when we get confirmation from IBM that the issue has been resolved and it is possible to upgrade.
