Hello,

What I see this is security feature of Little Snitch.
If you do need remote access Little Snitch, you have to enable the “Allow GUI Scripting access to Little Snitch” option in Little Snitch Configuration > Preferences > Security.

Hello,

NoMachine remote connection behaves as the local keyboard was directly attached to the server. Due to that, since you need to press Ctrl+C to copy on Linux, you have to press Control+C also when connecting remotely from the mac.

There is an open feature request that will cover that problem when it is implemented FR10M02977 – Provide an interface enabling user to configure modifier keys

I did not check startup scripts for the Linux Mint that loads correct theme on physical desktop. NoMachine starts command you mentioned in your post. I can recommend workaround that possibly you can use.
– Remove existing xfce settings for that user that has loaded standard xfce desktop.
rm -rf ~/.config/xfce4 or rm -rf /home/user/.config.xfce4
– log to the desktop with user physically or using NoMachine physical session
– then logout
– Create virtual desktop session

If it is headless machine I would disable lightdm to start on boot, you can do that by executing
systemctl disable lightdm.service and then reboot machine.

What I noticed is that you can use possible workaround to solve audio problem on Mac OS 12

sudo rm -rf /Library/Extensions/nxaudio.kext /Library/Audio/Plug-Ins/HAL/NMAudio.driver /Library/Audio/Plug-Ins/HAL/NMAudioMic.driver
sudo mkdir -p /Library/Audio/Plug-Ins/HAL/

sudo cp -a /Applications/NoMachine.app/Contents/Frameworks/bin/drivers/NMAudio.driver    /Library/Audio/Plug-Ins/HAL/NMAudio.driver
sudo cp -a /Applications/NoMachine.app/Contents/Frameworks/bin/drivers/NMAudioMic.driver /Library/Audio/Plug-Ins/HAL/NMAudioMic.driver

sudo chmod -R 755 /Library/Audio/Plug-Ins/HAL/NMAudio*
sudo chown -R "root:wheel" /Library/Audio/Plug-Ins/HAL/NMAudio*
 
sudo launchctl stop com.apple.audio.coreaudiod
sudo launchctl start com.apple.audio.coreaudiod

About MacOS 12 we have already opened Trouble Report that will be fixed in the following NoMachine versions TR12S10423 – Sound forwarding doesn’t work on macOS 12.

I am glad that it helped.

Furthermore, problem is with nvidia drivers and not with NoMachine software.

[fisherman]

Based on the output of the command vainfo executed with using drm and nvidia device that produced the crash, NoMachine will not be able to use that device and that was reflecting that NoMachine failed back to use software decoding.

Hello,

I am really happy that my post helped you.

[fisherman]

Can you check following command
ls -l /dev/dri

there should be list of devices, one of them renderD12x will be nvidia (will be renderD129 or some other number)
then run following command
LIBVA_DRIVER_NAME=nvidia vainfo --display drm --device /dev/dri/renderD129

In last command we do following:
– we say to vainfo to use nvidia driver with LIBVA_DRIVER_NAME
– we specify that nvidia device should be used by selecting it manually as renderD12x
– the most important part is that it uses DRM, instead of default X11 for display argument – we need to use it that way in our software

Please then show us output of the mentioned command.

Hello,

What I see here is the issue with your xorg Display configuration of the headless server, that needs to be adapted to use higher display resolutions.
NoMachine when connecting to the physical screen uses only provided resolution from the system, and as you show on your screenshots that was 1366×768.
If you want that NoMachine set up screen resolution, you could use NoMachine workstation virtual desktops, or ask NoMachine to create physical display for you. More info about mentioned feature can be found here: FR10L02842 – Giving the possibility to connect a physical session in NoMachine free version when the local X server can’t be found.

Hello,

Can you tell us if you are using new M1 Mac machine?
Audio does not work on Apple M1 as a server, we have opened new Feature Request to natively support Apple M1, you can see more here: FR12R04054 – Offering NoMachine packages natively built for Apple M1 Chip

Happy New Year too,

Can you tell us if you are using single or multiple display?
As well did you experienced something similar with other applications?

I tried version 6.12.3, and version 7.7.4 and both work as expected and without issues on Windows 11. This looks as the installation problem happened on specific environment.

Please can you try uninstalling NoMachine and reboot host and report if here are any uninstallation errors. After reboot verify if NoMachine folder still exists “C:\Program Files (x86)\NoMachine”.
If exists rename it and then install NoMachine again. Important is to reboot Windows after installing NoMachine to correctly load needed drivers.

If you still experience the problem, after new install, collect NoMachine logs ( DT11R00181 – Collect server and client logs manually ) and attach it to this post, or send to forum[at]nomachine[dot]com.
