Thanks so much Mario. I ran KbCheck whilst every other program was closed, and got the following warning:

PTB-WARNING: During PsychHID(‘KbCheck’): Some other running application is preventing me from accessing the keyboard/keypad/mouse/…!
PTB-WARNING: This is likely a security measure, e.g., to protect some active password entry field.
PTB-WARNING: Please identify and quit the offending application. E.g., some versions of Firefox are known to cause such problems…

But can’t seem to replicate this warning again (now KbCheck just doesn’t work, no warning). Running PsychHID(‘KbCheck’) I get the following warning:

PsychHID-ERROR: Could not enumerate and attach to all HID devices (HIDBuildDeviceList(0,0) failed)!
PsychHID-ERROR: One reason could be that some HID devices are already exclusively claimed by some 3rd party device drivers
PsychHID-ERROR: or applications. I will now retry to only claim control of a hopefully safe subset of devices like standard
PsychHID-ERROR: keyboards, mice, gamepads and supported USB-DAQ devices and other vendor defined devices and hope this goes better…
PsychHID-INFO: That worked. A subset of regular mouse, keyboard etc. input devices and maybe some vendor defined devices will be available at least.

The Apple experience, worth every penny…

That output is what you often get if Matlab is not allowed to low-level access the keyboard or other input devices. Either that, or simply keyboard input silently not going through. I had the same yesterday after installing R2020b. I followed the procedure described here:

Now it works again. However the entry for R2019b, which is still installed and nothing has been changed by myself there, disappeared, so i assume it fixed R2020b while breaking R2019b, or the security GUI simply is confused now. This on a brand-new macOS 10.15.7 installation. I haven’t seen so much sadness since Microsoft Windows Vista, although Vista was a masterpiece in design and quality compared to macOS Catalina’s security workflow.

The “default keyboard not detected” however, i can’t reproduce on a touchbar MBP 2017 …

Can you retry with this fresh PsychHID. This one is built on Catalina with the 10.15 Catalina SDK. Maybe it makes some weird difference:

Thanks so much Mario, I really appreciate it!!

Yes, this all started when I updated OS, and R2019b wouldn’t open (although still remained an icon).

The fresh PsychHID resolved all the problems on my system!! GetKeyboardIndices and PsychHID(‘Devices’, -1) now give the same answer, so KbWait now works perfectly, and the KbCheck and PsychHID(‘KbCheck’) errors I was getting also disappeared.

Seriously, thanks so much for all your help on this. I’m so sorry it has become such an ordeal, but I really appreciate it. And thanks to dcnieho as well for their help earlier on in the thread.

Unexpected, but good. I do not have any explanation why it would work now, or why it didn’t before on your machine. It was a shot in the dark. But keeping macOS stuff working is more about rain dances and praying to some gods than understanding and fixing things. Only in the world of Apple…

PTB 3.0.17 is now out and contains that fixed PsychHID file.

Luckily wrt. to expressing appreciation, since Monday we have our commercial services website up, which allows labs to express their appreciation in cash and contribute to the future development and upkeep of Psychtoolbox by buying community memberships with priority support (and other stuff): https://www.psychtoolbox.net

Thanks for the appreciation.

Hi Mario,

Thanks again for all your help. Every once in a while the new PsychHID file seems to crash. Matlab complains of a “segmentation violation detected”:

“This error was detected while a MEX-file was running. If the MEX-file is not an official MathWorks function, please examine its source code for errors. Please consult the External Interfaces Guide for information on debugging MEX-files.”

I’m attaching the full crash report below, but the only MEX file running appears to be PsychHID.

Easy enough for me to restart MATLAB, but it’s happened a few times so thought it might be worth bringing to your attention.

Thanks, again, for all your help,

Paul

Ja, that’s nothing new. Not a PTB bug, but yet another Apple macOS bug in the Catalina trainwreck, possibly earlier versions as well. Googling for “secure input” and IOHIDDeviceGetValue points to various applications having this crash problem with low level input. It seems to have gotten worse with Catalina though, according to googling.

It usually happens if something on your machine wants secure keyboard input, e.g., some password entry field or other confidential data entry field as part of a webpage. The trainwreck won’t just block low level keyboard input for applications like PsychHID, but simply crash them, just what one expects from an Apple product nowadays. No known workaround, just being very careful about what one runs in parallel or in the background. Password managers etc. would probably trigger the same problem.
