New IAM admin user sees “You are not authorized to perform this operation”

I am trying to get started with the AWS CLI on OSX. I installed aws via pip. I have created a new user in IAM and attached the pre-built AdministratorAcce

Make sure you are not creating the security group in VPC, if this is the case you need to pass default VPC ID as a parameter.

Also try this with different regions:

aws configure set region 
aws ec2 describe-security-groups

NOTE: AWS has started providing default VPC's in most of the regions.

Hope this helps and resolve your issue.
