There is an issue with permissions and iohub in OSX, or more accurately an issue with OSX in how it handles permissions. You can override it, but I’ve had somewhat mixed results and it looks like you need to re-enable it every time you update psychopy. (Windows and Linux do not have this issue.)
In your system preferences, go to ‘security and privacy’ and then to the ‘privacy’ tab, and in the list on the left choose ‘accessibility’. Drag psychopy into the list of programs from your apps folder, and check it. It should then allow iohub to start up.
Hello Jonathan,
Thank you for your comment,
Unfortunately, it doesn’t works in my macs (both 10.10.5, two laptops and two mac pros)…
Is it possible that the problem is not the psychopy, but the ‘so’ file provided in Tobii SDK?
Can you get iohub to work without the eye-tracker? The error you are getting right now is not eye-tracker specific, it’s just saying that it can’t start an iohub server. Try some of the other iohub demos and see if you get the same error. If so, then the issue is iohub. If not, then it might be something Tobii-specific.
Below is the result of running “selectTracker” demo in Coder of Standalone version of Psychopy 1.84.1.
I added ‘modules’ as paths in Psychopy preferences.

Since, when I remove path, the error message changes like below, I think the issue is something btw, Psychopy and SDK files.

keyboard demo works properly.
besides, the sample python script in SDK also works well.
I think the problem is communication (or access) to dylib or so file from psychopy.
I tried with different mac pro with 10.10.5
I installed macport, and installed psychopy manually.
All other demos works properly.
however, when I run selecttrackers, and select tobii, below error message is shown.

It seems the error comes from duplicate python execution.
when I put the compiled version in site-packages directory of macports python directory,
I can use iohub eye tracking examples properly.
