This should provide a fix:

> [@Error -- ApplePersistenceIgnoreState: Existing state will not be touched. New state will be written to (null)](https://discourse.psychopy.org/t/error-applepersistenceignorestate-existing-state-will-not-be-touched-new-state-will-be-written-to-null/23964/4):
>
> Just type in terminal window
> 
> ```auto
> defaults write org.opensciencetools.psychopy ApplePersistenceIgnoreState NO
> 
> ```
> 
> and it should be all set.
