I know nothing about Macs but I googled this error and it looks like a lot of Mac users are running into issues like this (with different software). This page claims to have a fix: https://appletoolbox.com/seeing-error-operation-not-permitted-in-macos-mojave/
This is a discussion of what appears to be the same bug for an unrelated software package. The dev had to make changes to the code to fix the issues (ask for permissions), although some users report some successes (bobsomers): https://github.com/darktable-org/darktable/issues/3107 I hope this helps. Sorry I cannot do more. -Alan On 3/11/2020 9:26 AM, Tetchie Dalusong wrote: > Good day, > > May I ask if PSPP works in Catalina.
