Same problems as previously reported and answered by Lauren Mittelstaedt, i.e. Logos comes up on previous exit page, IMac generates a multicolored ball and within a few seconds the login page dissapears. I have installed a new Logos version: problem persists. Mac Font test could not be loaded because it was from an unidentified developer. I am back at where I was a few days ago. I attach the bug report1526.LogosLogs.yvesmichiels.20140603-133852.zip
Thanks
