@VolodymyrGalushka, @tigertim08, @Andorin, @mac-dj73, @dy008

Please open system terminal and provide an output of

python -c "import ssl; print(ssl.OPENSSL_VERSION)"

[ivankravets]

Try in system terminal

/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
brew update
brew install openssl

After that, please remove ~/.platformio/penv folder and restart IDE.

[ivankravets]

Please upgrade PIO IDE to 2.1.0

[VolodymyrGalushka]

Thanks

Simply upgrading pip may also help but need to upgrade pip without using pip (because of recent TLS support deprecation by Python.org sites). See this SO post for details: https://stackoverflow.com/q/49768770/1526703

Activate your enviroment and run this command. Upgrade your pip version with manual command. Old pip version don't supported this tls version.
