I just upgraded to 5.2.21 and ran into a problem trying to change the connection preferences.  In order to change anything, I need to authenticate and always get an “Authentication failed, please try again” error.  Interestingly, it takes about 5 seconds before finally failing.  It’s as if something is timing out.
The computer is a “Late 2013” MacBook Pro running El Capitan 10.11.6.  It’s worth noting that I have a multifactor authentication package installed.  That is, when I log in to MacOS, I don’t use a regular password; I insert a USB dongle and then type in a PIN# (that’s unique to the dongle).   I suspect the authentication errors may be related to this.
Has anyone at NoMachine tested NX with a Mac in this configuration?  Also, does NX write any log files anywhere that would have more details and maybe confirm my suspicion?
 
Thanks very much,

BTW: For now, I’ve been able to work around the authentication problem by launching nxplayer from the command line using sudo.  From there, I can go into the settings page and make the changes without having to authenticate.  I’d still like to see this issue resolved properly, though.
