Compatibility issue between OS X, matlab and old psychtoolbox version

1
Hi,

I'm using psychtoolbox 3.0.8 with Matlab R2014a 64-bit in Mac OS X 10.7.5.

The funciton 'Screen' is not working and I wonder if it's because of a compatibility issue between these versions.
I tried newer version of psychtoolbox but they are not compatible with OS X 10.7.

Do you have any clue how to fix this without upgrading Mac OS?


When I run 'PsychtoolboxVersion'
Error using PsychtoolboxVersion (line 188)
Unrecognized Psychtoolbox platform


When the the function Screen is directly called:
screens=Screen('Screens')
OR
[w,rect]=Screen('OpenWindow',screenNum);

I get the following error message :
Error using Screen
Too many output arguments.


When the function HideCursor is called, I get the following error message :
Too many outputs requested. Most likely cause is missing [] around left hand side that has a comma separated list
expansion.

Error in AssertMex (line 123)
extensionName=mexExtensions{extensionNameIndex};

Error in Screen (line 162)
AssertMex('Screen.m');

Error in HideCursor (line 57)
Screen('HideCursorHelper',0);


Error in MyScript (line 51)
HideCursor;


Thanks for your help,

Hi,

To follow up, I guess I'm running into a similar issue as this guy (except that I'm using on osx 10.7):
https://fr.mathworks.com/matlabcentral/newsreader/view_thread/337754

My understanding is that I should use psychtoolbox 3.0.11 (should be compatible with MACI64), but I can't put a hand on it on the web or download it with DownloadPsychtoobox most likely because osx 10.7 doesn't support OpenGL-based versions.

Could you please provide me a link to download psychtoolbox 3.0.11?
If you have any other guess, could you please help me fix this?

Thanks in advance for your help,

Sandrine
