macOS Ventura (13.0) included a change in behavior that causes an error (100093) when copying files to some external drives (which is what our pedal looks like for firmware updates).
The problem was fixed in macOS Ventura 13.1.
You can update your Mac by opening the System Preferences:
Select Software Update:
In the Software Update window, click Upgrade Now:
Before you update your Mac, you may want to confirm that all of your critical software supports macOS Ventura. Since you would have had to have already upgraded to Ventura 13.0 to experience this problem, upgrading from 13.0 to 13.1 should not cause any new issues.
Workaround for macOS Ventura 13.0
If for some reason you need to stay on macOS Ventura 13.0, you can use the Terminal application. Open a Terminal and navigate to the directory where the .bin file is, then type:
$ cp -X particle_2.2.0.p.bin /Volumes/PARTICLE
(replace PARTICLE with the pedal name for other pedals - it is the name of the external drive.)
Once the LED turns green - showing that the firmware update was successful - close the Terminal window, eject the pedal's drive, and power cycle it.
