PsychoPy 3.0 2021.1.1.2 won't open on macOS Mojave

Downloaded the PsychoPy app from the standalone version on psychopy.org but it does not open on my computer. I am using MacOS Mojave. I’ve used psychopy tons of times without issue but this time I get a dialogue box with the message “PsychoPy error” with button options to visit the console or terminate Psychopy.

the console has these messages with regard to Pyschopy:
27366555: RECEIVED OUT-OF-SEQUENCE NOTIFICATION: 0 vs 690, 513,

OSErr AERemoveEventHandler(AEEventClass, AEEventID, AEEventHandlerUPP, Boolean)(aevt,oapp handler=0x1000fffc0 isSys=NO) err=0/noErr

OSErr AERemoveEventHandler(AEEventClass, AEEventID, AEEventHandlerUPP, Boolean)(aevt,odoc handler=0x1000fff90 isSys=NO) err=0/noErr

OSErr AERemoveEventHandler(AEEventClass, AEEventID, AEEventHandlerUPP, Boolean)(GURL,GURL handler=0x1000fff60 isSys=NO) err=0/noErr

i also tried to download using pip and homebrew and nothing has worked! I really have to work on an experiment so I am super worried

In terminal could you try doing:

cat ~/.psychopy3/last_app_load.log

that might give us some clues as to what’s gone wrong.

Alternatively there’s further advice here on cleaning out preferences in case those have become broken:

hi @jon thanks so much for your help!

After trying to download the packages without success i figured my computer’s os was probably to blame so I wiped it out and updated my os to big sur which i am realizing now may have been a mistake as I am reading a lot about the graphics changes apple made during the upgrade, basically,
I figured out how to get the commands to run and it seems like psychopy can’t find opengl or AppleIntelKBLGraphicsGLDriver.bundle

I know this is was a common error but that you fixed it a while back so I am confused as to what is going on!

Here are the exact console messages:

Mar 22 23:26:11 Leahs-MBP PsychoPy[36410]: getattrlist failed for /System/Library/Extensions/AppleIntelKBLGraphicsGLDriver.bundle/Contents/MacOS/AppleIntelKBLGraphicsGLDriver: #2: No such file or directory
Mar 22 23:26:11 Leahs-MBP PsychoPy[36410]: getattrlist failed for /System/Library/Frameworks/OpenGL.framework/Resources//GLRendererFloat.bundle/GLRendererFloat: #2: No such file or directory

i am running python 3.9 and have downloaded the standalone app for psychopy3. i’ve also used pip to install psychopy and after a few errors related to hdf5 not loading i got it to install fully. despite this when i click on the app icon to get the gui to open i get the “terminate” or “open console” options. I have deleted the configuration files within the psychopy3 app as well.

Sorry again for all the bother and thank you!

I downloaded a fresh version of the standalone and by some magic it worked!

Glad you got it fixed Leah. For Big Sur it’s important to make sure you aren’t accidentally running an older version - best thing on that platform is to pu tall the older versions in recycling and empty the bin so that it doesn’t accidentally use one (e.g. when you double-click a file).
