Cannot Download for M2 Macbook Pro

Programming Help

Hi - I cannot for the life of me download ptb. I get this error when I use ‘SetupPsychtoolbox’ :

Error using PsychtoolboxPostInstallRoutine
Tried to setup on native Matlab or Octave for Apple Silicon 64-Bit ARM. This is not supported.

Error in SetupPsychtoolbox (line 337)
PsychtoolboxPostInstallRoutine(1);

I am forced to use ‘SetupPsychtoolbox’ because the “easy” installer is now outdated. I am using the Intel version of Matlab, after first trying the Silicon version. All help is very much appreciated, thank you.

It is indeed sad that the majority of our users is so short sighted that they deprive us of any funding needed to deal properly with such issues caused by decisions at GitHub and Microsoft that we don’t have any influence on. You get what you pay for.

That is by design for ARM native Octave and Matlab. Running SetupPsychtoolbox on Matlab for IntelMacs under Rosetta2 emulation is supposed to work though and was successfully tested iirc. Is your PTB fully up to date? What’s your Matlab version (output of ver command? What’s the output of computer?

Thank you for your response.

  • Matlab v23.2.0.2515942 (R2023b - update 7)
  • Psychtoolbox v3.0.19 (Feb 17
  • computer: ‘MACA64’

That’s running the Matlab Silicon/ARM version, not the Intel version.

Output of computer('arch') and mexext should confirm that.

Thank you very much, you have solved my issue. I had both the intel and silicon versions downloaded, and even though I was opening the intel version it seems the silicon was taking priority (that or I just mislabeled them). I just re-downloaded the intel version and am all good. Again, thank you very much!!
