How to find Rohos log file?

Since version 1.4.3 Rohos doesn’t write its log into Console by default. First you need to enable “write log” in Preferences and then do actions that lead to bug in order to log them.

In order to find log strings:

  1. Open up Console (/Applications/Utilities/Console.app)
  2. Select system.log
  3. Select & Copy Rohos log strings (prefixed with ‘Rohos logon’ or ‘SecurityAgent’)

To select and copy multiple strings:

- click on 1st string,
- scroll to last string
- shift + click on last string and copy them (apple + c).
