To Reproduce
Steps to reproduce the behavior:

1. Install lazydocker by homebrew, following the docs
2. Run lazydocker
3. The alert asking for permission to send anonymous data will be displayed. I accepted that
4. See error

Expected behaviour
I should see the dashboard running. That happened without any problem in the second running.

Desktop (please complete the following information):

• OS: MacOS 10.14.5 Mojave
• Lazydocker Version 0.3

I think this is fixed in the latest version. Could you give that a try?
