After determining the port name, go to the directory where the bootloader FW file
WisCore_RAK4631_Board_Bootloader.zip
is located.
Then execute the following command:
adafruit-nrfutil --verbose dfu serial --package WisCore_RAK4631_Board_Bootloader.zip -p
/dev/ttyACM0 -b 115200 --singlebank --touch 1200

There are two ways to update the RAK4631 bootloader in macOS:
If you have Python installed, you can follow the same steps for Linux.

make it executable.
Usually, the
adafruit-nrfutil-macos
file will go to the downloads folder.

your macbook
cd /Users/username/Downloads
or you can directly try
cd Downloads
.
And then execute this command:
chmod +x adafruit-nrfutil-macos
