Open Sesame does not launch

milliechesterman

I have downloaded and installed open sesame on my Mac but every time I try to open it and use the app the icon just bounces in the doc then disappears.

Hi @milliechesterman ,

What happens if you start a terminal, and then launch OpenSesame from there? You can do that by executing the following command.

/Applications/OpenSesame.app/Contents/MacOS/OpenSesame

Do you see any error messages?

Hi @gbzn ,

I suspect that the error that you get when launching from the console results from the Anaconda base environment that is activated. I suspect that this causes a confusion between the Python environment of the OpenSesame app and the Python environment from Anaconda. What happens if you first run:

conda deactivate

And then launch OpenSesame:

/Applications/OpenSesame.app/Contents/MacOS/OpenSesame

My guess is that you will still get an error message, but a different one.

Hello @sebastiaan ,

Thank you for your answer.

I tried what you said and here's what appears in the terminal :

@gbzn Are you running Mac OS Big Sure?

@Daniel Does this look like the Big Sur issue to you?

Daniel

I think this is the Big Sur issue. But @gbzn's last output is a bit strange, because it appears as if the ` conda deactivate` command is causing this error message. So either, it is not OpenSesame related, or he forgot to paste a (large) part of the actual console output.

sebastiaan

@Daniel Thanks, I suspected it was Big Sur. (The command that triggers the error is actually the line after `conda deactivate`.)

Daniel

Ah I see, I just misread it. This should be solved once we package OpenSesame with a python version greater than 3.7

Hello again,

Thank you for your answers although I'm still running macOS Yosemite ...

gbzn

Hello again,

Did I need anaconda to launch OpenSesame on my mac ?

Because I tried to install it and launch OpenSesame with it as in the tutorial on the website but it still doesn't work. and now that i've uninstalled it, when I write "conda deactivate" in the terminal, it does this :

So I have really no idea what to do to make Open Sesame launch on my computer now...

Thanks in advance for your answers

Liliann_L

same problem :(

did you find an answer?

sebastiaan

Hi @Liliann_L and @gbzn ,

If you're running Mac OS Big Sur, then you can take a look at this post for a possible workaround.

If you're running a different version of Mac OS, then I don't know what causes the issue. In that case, you could consider installing OpenSesame through Anaconda instead of using the package:

• https://osdoc.cogsci.nl/3.3/download/#anaconda-cross-platform

Hope this helps!

Hey @sebastiaan,

just wanted to let you know that it seems to be a problem related to el capitan. I tried all the recommendations but nothing worked. Since I changed the system to catalina everything works fine!

Thank you for your help, anyway!
