    I’m evaluating NoMachine for use at work and other places.   I installed on two Macs here at home: one a Retina Macbook, the other a Macbook Pro (cylinder).  Easy.  Unfortunately, when I go to connect to my remote Mac (both running Catalina BTW), though I was able to type in my name and password, it continues to say no sessions are available.

    I approved the system security extension on both systems.

    I’m not running the firewall.

    Can someone tell me what I’ve missed here?

    Hello.

    First lets rule out the easy stuff.

    There could be two issues here:

    1. When on “no sessions available” screen, please make sure the view is set to “All desktops”.

    2. Please make sure the user you are connecting with is marked as an administrator for NoMachine.
    On licenses other than Enterprise Desktop we have something called “restricted access” to physical desktop, and the user has to be specifically marked as administrator to have full access to Login Window and desktop sessions.

    If the user account has already been used to access NoMachine, please use:

    /etc/NX/nxserver --useredit username --administrator yes

    if not, please use:

    /etc/NX/nxserver --useradd username --administrator yes

    And try to connect again.

    If this does not help please gather logs for investigation.

    As it is Catalina, please gather information from the MacOS system log, preferably by running:

    # cat /var/log/system.log | grep -e nxserver -e nxnode -e nomachine >> system.debug

    and

    /usr/bin/log show --debug | grep -e nxserver -e nxnode -e nomachine >> log.debug

    Also please collect NoMachine logs.

    Article on how to collect logs:

    https://www.nomachine.com/DT10O00163 (“How to gather debug logs for support requests”)

    Please include the system.debug file and send them to forum[at]nomachine[dot]com using the title of
    that forum’s thread as the mail’s subject.

    Just an FYI, for Catalina users we have an article which might be useful:
