Nugroho's blog.: Can not Detect Arduino Nano on El Capitan?

Wednesday, August 10, 2016

It because the nano used CH341 usb to serial adapter that will not install because El Capitan enforces kext driver signing.

So, I trace the step from https://tzapu.com/making-ch340-ch341-serial-adapters-work-under-el-capitan-os-x/

...and it works again, :)

To disable kext signing:

- Reboot and press CMD+R immediately after the chime to enter Recovery Mode

- Open Terminal from Recovery mode

- run the command csrutil enable --without kext

- run the command reboot
