Something that would help us a lot to understand the problem would be this:

  1. Open the application called ‘Terminal’
  2. In this application run the command:

eos-diagnostics

  1. The above command will create a file with the information of your system (example: eos-diagnostic-160614_111731_UTC + 0100.txt); Send us this file so we can analyze and see a possible solution

eos-diagnostic-180919_021237_UTC-0600.txt (657.3 KB)
here is the file
