Thank you for your help.
Upgrade to Mac OS 10.15.5 Catalina and
SPRESENSE 2.01 ArduinoIDE version 1.8.13
I can no longer see the USB-serial port in this environment.
Reinstalling CP210x USB to UART Bridge VCP Drivers will not work
"Unblocking the security settings manufacturer" during installation is not allowed.
Reloading the driver using the following methods will not work
The installation will end without any errors.
No error message when loading driver with command
However, ArduinoIDE does not show the serial port...
I'd appreciate it if you could give me some tips.
After updating the macOS version, I also had a problem with not being able to install the latest driver, but I was able to install the old driver that I installed before, so I opened the serial port.
This is a bit gross, so in my case I reinstalled the operating system myself and installed the latest drivers.After reinstalling the operating system, I was able to install the driver without any problems.
If I update the operating system after installing the old driver, I wonder if I can install the new driver...
