    I am running OS X 10.10.3 (14D136) and NoMachine 4.6.4. I am unable to unlock settings. I have two admin users – one is AD mobile account, the other is a local admin account. Authentication fails for either of them. I just get the spinning over the NoMachine window and after several seconds go back to the user / password screen.

    Any ideas what could be causing this? This bug makes NoMachine unusable, especially that I do not want to allow remote connections to my computer.


    Thanks in advance for help.



    This is what appears in system log during auth attempt:

    Hey rejsmont!
    We’ve documented the problem causing that log, you can see it here:


    Anyway it doesn’t look to be related to the authentication problem, we’ll get back to you soon with more details/questions. Thank you.


    I have this problem as well, i.e., I am unable to change anything in Preferences –> Connections –> Connection Preferences that requires administrator privileges.  On the “Authorization required” screen, I type in a password for my administrator account, and I get a spinning wheel for a few seconds, and then it returns to the “Authorization required” screen as if nothing happened.  (I’m adding these terms to make it easier for others to google this problem.)  (Curiously, I can then type in sudo commands in a terminal window without it prompting for a password, so it did in fact successfully authenticate with sudo.)  I am running Mac OS X 10.10.5 and NoMachine 4.6.16.  According to the 3rd post above, this problem should be fixed in version 5:




    Everyone, please update to version 5. The TR https://www.nomachine.com/TR07M05813 was fixed in this release.


    I am still having this problem running 10.8.5 with NoMachine version 5.0.43.  Any attempt to change something in preferences results in a warning “Authentication failed, please try again.”  Is there some other way to force it to let me authenticate?  I never get a prompt.


    Hi idux.
    Could you please help by retrieving some logs? This is the list of commands to execute:

    – Open Terminal
    tar -czf log.tar.gz .nx/M-*
    tar -czf system.tar.gz /var/log/system.log
    ls -l /Applications/NoMachine.app/Contents/Frameworks/bin > dir.log
    ps -ef | grep nx > ps.log

    Send all the highlighted files to forum[at]nomachine[dot]com.
    Thank you!


    Hi. I am having the same problem on OS X 10.10.5 with NoMachine 5.0.47. Any hints?



    @imans, see the thread above. If possible, send us the additional information that Tor has already requested. Thanks!


    @Britgirl, I am using NoMachine on a secured company network. I believe the company’s security policies won’t allow me to share those files…

    Please let me know if you have any hints that might work. Thanks!
