Q:

HyperLedger Fabric installation is hanging in the middle and not progressing in MacOS?

I'm trying to install HyperLedger Fabric on my System (MacOS Sierra 10.12.6) but I keep getting stuck. 
According to this link (https://hyperledger-fabric.readthedocs.io/en/latest/install.html), I'm using this command: curl -sSL https://raw.githubusercontent.com/hyperledger/fabric/master/scripts/bootstrap.sh | bash -s 1.3.0-rc1, however, it doesn't proceed after the first substep- as shown in the image below.
Strange thing is, it had proceeded past this stage in a previous attempt but had ended up getting stuck further along the way and not showing any output/update, so I terminated it and ran the same command in a adjacent directory (at the same location, in the same parent). Now its getting stuck here. 
I've installed all requirements according to the documentation. Can anyone tell me whats going on? Why is my installation hanging and why am I not able to install the project?
Progress:

also, in ~/.bash_profile I've added the following:
# Manually added for HyperLedger Fabric Go installation
export GOPATH=$HOME/go
export PATH=$PATH:$GOPATH/bin
export PATH=/Users/deepak/Desktop/Project/BlockChain4/bin:$PATH

Each new iteration/installation attempt, I start in a new folder BlockChain, BlockChain2, BlockChain3, and so on. 

A:

You seem to have an issue with pulling the docker images.
Unrelated to 1. How did you install go?
