@m5stack: I finally fixed "my" problem being not able to "see" the Atom Matrix on a mac with 10.15.x!!! At first I suspected a Wacom tablet driver which interferes with my serial port, but at the end it was an old FTDI driver helper named D2xxHelper. I figured out the problem by issuing this command

sudo ioreg -lirc IOUSBHostInterface

It gives detailed information on the USB connections and its drivers. For the "M5 Serial Converter" it stated the the D2xxHelper as driver (helper). By removing this old driver and rebuilding the kernel cache I was finally able to "see" my Atom Matrix on Catalina. Enclosed my commands:

sudo rm -rf /Library/Extensions/D2xxHelper.kext
sudo kextcache -i /

After this I've rebooted my mac.

@m5stack : Yes, I did. By further investigating the driver, it looks like they are not working due to signing issues. I found this thread https://www.ftdicommunity.com/index.php?topic=409.msg1171#msg1171

I'm waiting on this rerelease, than I'll let you know. Thanks.

@m5stack did you dig any deeper into this? I'm still unable to use the M5Atom Matrix on my mac with Catalina. I started over again by installing and deinstalling stuff, but no new device appears. The system recognizes the M5Atom Matrix by naming a M5 Serial Converter with following information:

Produkt-ID: 0x6001
Hersteller-ID: 0x0403 (Future Technology Devices International Limited)
Version: 4.00
Seriennummer: 79525701B4
Geschwindigkeit: Bis zu 12 MBit/s
Hersteller: M5STACK Inc.
Standort-ID: 0x14500000 / 6
Verfügbare Stromstärke (mA): 500
Erforderliche Stromstärke (mA): 100
Zusätzlicher Betriebsstrom (mA): 0

I also applied the firmware update many times successfully.

@m5stack : Any other ideas? I'd like to play with it.

@m5stack said in M5StickC and ATOM on MacOS Catalina can't upload programs solustion:

/Library/Extensions/FTDIKext.kext

I had access to a Windows machine and was able to use the easy loader on my M5Atom Matrix. It is working on Windows.

For my mac:
Yes, I installed the FTDI driver, but they did not work. I've removed them as suggested, but it didn't change anything. There is still no device appearing in /dev/, so it is not accessible.

@m5stack

No, the is (un)fortunately no Windows machine. I'm a little confused about the fact, that the above mentioned firmware is running without any problem. So there needs to be a connection between mac to m5atom in some way — or how is it writing to the device?

@m5stack

I'm on macos 10.15.3 and I'm asking myself too, where is G0 on the M5Atom Matrix? Although I was able to apply the described firmware, I'm not able to connect via UIFlow IDE nor Arduino IDE (1.8.9).

By the way: almost no image gets displayed on Safari from the documentation — neither iPad nor mac.
