Hello, where can I find the factory test program for the New M5Core3? I am very interested in the cam Part of the software.

Hello,
I worked with a M5Stack, Arduino 1.8.x and MacOS Mojave and every thing with USB was fine.

I updated to MacOS Catalina and updated Arduino to version 1.8.10. Every with USB for my M5Stack was fine, too. If I check the USB driver I can see:

$ ls /dev/tty.*
/dev/tty.Bluetooth-Incoming-Port	
/dev/tty.SLAB_USBtoUART	
/dev/tty.usbserial-017D2264

If I like to flash my M5Stick-C and I connected it, I can see only this:

$ ls /dev/tty.*
/dev/tty.Bluetooth-Incoming-Port	
/dev/tty.usbserial-9D5AE08545

With the old and the new Arduino-version the "tty.usbserial-9D5AE08545"-driver did not work. Arduino needs a "SLAB_USBtoUART"-driver.

What can I do?

Yes, I know today Catalina is a beta-version, but it will released shortly.

@lukasmaximus Thank you for your help. In the meantime I tested with Catalina Version 10.15.2 (19C57) and with the drivers from FTDI. I can not program the M5StickC, but the Arduino Monitor did work!

I found the problem: The M5StickC didn't change to upload mode!
I connected a small button between GND and G0 at the 8-ext Pin connector and I pressed the button if Arduino like to upload ("Connecting........_____...."). The workaround worked fine.
