Can't get PyTrack to work due to firmware issue

I was planning a project with my PyTrack v1.0, that I never really used before. Unfortunately, I can't even get the example code to work.
When I try, pycoproc.py is raising an exception:
ValueError('Firmware out of date')
I was able to upgrade the firmware of my FiPy to 1.20.3.b0, but can't update the PyTrack firmware. When I try, I get the dreaded dfu-util: Cannot set alt interface zero bug. (Running macOS 10.14.6).
Is there any way at all to proceed? All suggestions are welcome!

I have a similar issue, I'm trying to update the firmware of my Pytrack v1.1 but I get an error. Here is the output when I run the DFU-util tool
$ dfu-util -D pytrack_0.0.8.dfu dfu-util 0.10 Copyright 2005-2009 Weston Schmidt, Harald Welte and OpenMoko Inc.

I'm working on Mac OS 10.15.7, but as this errors only occurs on Mac OS I'll try to update my Pytrack using a Windows system as recommended
There are two solutions I can think of at this time. The easiest being to use a different operating system (unfortunately, the error only occurs on MacOS). Other things you could try is to downgrade the
libusbpackage to version 1.0.22, and use
dfu-util0.10, that does work at the moment (we're in communication with the dfu-util team to get the issue resolved).
Sorry for the inconvenience
