IF you have recently upgraded to macOS Sonoma, you will find that SPSS will no longer work, as macOS Sonoma is not one of SPSS’ supported platforms and is incompatible with most versions of IBM SPSS Statistics. https://www.ibm.com/support/pages/node/7041357
There is however a manual fix that not all users have successfully applied to SPSS Sonoma users.
How to apply the hot fix:
1) Close all instances of Statistics 29 Desktop
2) Navigate to the ../lib subdirectory in the Statistics 29 Desktop installation path.
(e.g. "/Applications/IBM SPSS Statistics/SPSS Statistics.app/Contents/lib/")
3) Locate the following file and back it up to a separate folder, such as your Desktop.
libplatdep.dylib
4) Copy the following interim fix files to the 29 installation folder located in step 3.
libplatdep.dylib
5) Make sure the installed files have correct permissions (e.g. chmod 755)
6. IBM SPSS Statistics 29 is now ready to be used.
