[SOLVED]Problems installing Laravel Homestead on MAC

I'm trying to install laravel homestead (with php 7) on my local machine (Mac OS X El Capitan). I've already installed vagrant and Virtualbox.
When I follow the documentation I start with the command vagrant box add laravel/homestead. This doesn't cause any problems:

The following step is:

cd ~
git clone http://ift.tt/SBuys2 Homestead

That also works. The next step is:

bash init.sh

This command should create a Homestead.yml in a hidden directory ~/.homestead. This doesn't happen! He creates the Homestead.yml in the ~/Homestead directory.... .
Then I've edited the Homestead.yml in my ~/Homestead folder to:

---
ip: "192.168.10.10"
memory: 2048
cpus: 1
provider: virtualbox

authorize: ~/.ssh/id_rsa.pub

keys:
    - ~/.ssh/id_rsa

folders:
    - map: ~/projects
      to: /home/vagrant/projects

sites:
    - map: homestead.app
      to: /home/vagrant/Code/Laravel/public

databases:
    - homestead

# blackfire:
#     - id: foo
#       token: bar
#       client-id: foo
#       client-token: bar

# ports:
#     - send: 50000
#       to: 5000
#     - send: 7777
#       to: 777
#       protocol: udp

Then I've tried to run vagrant up in ~/Homestead folder. But I'm getting the following error:

Can someone help me with the installation of Homestead?
