I am new please help

hello everyone I am new to Arduino , I am using an older IMac (21.5 " mid2011)
2.5 GHz intel core i5 processer
16 g Ram

I bought it use from someone and it was wipe clean

I am tryin to learn about Arduino and I look up some videos on youtube

I downloaded the Arduino IDE and install the FTDI usb driver and added the
link in the preference

I bought the esp8266 node mcu 1.0 12E module

I have two problems I can seem to solve one is my board shows as
/dev/cu.SLAB_USB to UART


when I try to upload I get this message

Arduino: 1.8.12 (Mac OS X), Board: "NodeMCU 1.0 (ESP-12E Module), 80 MHz, Flash, Legacy (new can return nullptr), All SSL ciphers (most compatible), 4MB (FS:2MB OTA:~1019KB), 2, v2 Lower Memory, Disabled, None, Only Sketch, 115200"

fork/exec /Users/ramdass/Library/Arduino15/packages/esp8266/tools/python3/3.7.2-post1/python3: no such file or directory
Error compiling for board NodeMCU 1.0 (ESP-12E Module).

This report would have more information with
"Show verbose output during compilation"
option enabled in File -> Preferences.

please help thanks a lot
thanks (mod edit)

I can't help with Mac problems, sorry.

It does not matter how your board shows as long as it shows when you connect it and disappears when you connect it.

I suggest that you remove your email address unless you want to receive spam.


fork/exec /Users/ramdass/Library/Arduino15/packages/esp8266/tools/python3/3.7.2-post1/python3: no such file or directory

The problem is the ESP8266 platform has a tool dependency on Python 3, but rather than installing a dedicated copy of Python 3 with the package, the ESP8266 platform developers assume you have Python 3 already installed at /usr/local/bin/python3. /Users/ramdass/Library/Arduino15/packages/esp8266/tools/python3/3.7.2-post1/python3 is just a symlink to that location. So either you have Python 3 installed somewhere else, like /usr/bin/python3, or maybe you don't have Python 3 installed at all. If the former, you need to modify the symlink, as described here. If the latter, you need to install Python (and possibly modify the symlink as well if it was installed to a location other than /usr/local/bin/python3.
