Apple macOS 11 (Big Sur) does not support SPSS 26
Posted: Thu 19 Nov 2020, 4:01pm.
If you use SPSS 26 on your iMac or MacBook, please do not upgrade your device to macOS 11 as there are compatibility issues and SPSS will not run properly. SPSS 26 is compatible up to macOS 10.15 (Catalina)
We will update you when a licenced version of SPSS is available for Big Sur.
