[chuck-users] trackpad problem

I have not updated all 20 yet. But I just tried another one with Sierra OSX and got the same behavior.

If it is not OSX dependent, seems that it must be something particular to that specific hardware model: MacBook Pro (13 inch, Mid 2012).

The trackpad or an external mouse works fine in every other program.
Within miniAud, they are recognized as HID devices.
It will connect to them and print the hid.name
But it won't read any HidMsg data.
It won't even trigger hidEvent => now;

Just confirmed that thinks are working as expected on my MacBook Pro 15in mid-2015 with mac OS 10.14.5. But perhaps something changed between .5 and .6.

Have all 20 been upgraded / is it failing with all of them?

I had this problem with my (sadly now defunct, as of a month ago!) 2011 MBP after years of use.  You can try:

1.  Resetting the System Management Controller.  Shut down your Mac, be sure the power cable is plugged in, then press (left side) Shift-Control-Option and power-on keys all at the same time.  Hold for about 5-10 secs, and reboot if it doesn't automatically (I can't recall if it does).

2.  Reset the the PRAM/NVRAM.  Shut down your Mac.  Push the power-on key and hold down Command-Option and the "P" and "R" keys and hold them while the machine boots.

3.  It may be a battery issue.  The older batteries used to swell up when they got tired, and it may be pushing on the back of your trackpad.

hope this helps --

I have an older MacBook Pro (13 inch, Mid 2012). [actually I have 20 of them for a class]
Recently updated to 10.14.16 (Mojave), and am using miniAudicle 1.3.6

** I can no longer receive any mouse/trackpad data **

The Device Browser recognizes both the internal trackpad and an external USB mouse.
hid.openMouse is successful. hid.name<http://hid.name/>() works.
however it will not receive any live data from the mouse.

Keyboard works fine. Accelerometer works fine.

Any thoughts?
