Artemis Red Nano bootloader not working on Mac OS X Sequoia 15.1

Hi folks!

I recently upgraded by Mac to Sequoia 15.1 and now I am unable to flash my Artemis Red Nano. It says the SVL Bootloader does not work. I verified the bootloader does work by using another Mac with an older version of the OS. The Serial Monitor does work, however, so I think the serial port configuration is OK. Has anyone else seen this or have a fix?

Here is the output from the Arduino IDE:

Artemis SVL Bootloader
Target failed to enter bootload mode. Verify the right COM port is selected and that your board has the SVL bootloader.

Thanks,
Karl

Someone the other day posted they had to enable unkown dev mode; see if that helps yours?

Thanks! Sadly, it did not fix it. I think that Security setting is for running apps not coming from the store or from known developers. And the app runs just fine.
