Thx for your input btw 
I got the 4.9 on my pi2ā¦but at first i was trying with 4.7.
Here is a post that i made when i was having problems compiling @patrikolausson version:
but thats a totally different error message.
Really no idea about how to make this work with vero2ā¦Maybe there are some things missing or the architecture is differentā¦I dont know 
ā¦@sam_nazarko should be able to clear things up.
Hi ā didnāt see these posts, apologies.
My long term goal is to get VNC in the App Store. You cannot simply copy the Pi instructions, because Vero 2 uses a different windowing system.
In the interim, I will create a [HowTo] for installing VNC on the Vero 2.
Sam
@Sandbird, Iāve PMād you some instructions for you to try. Let me know how you get on. Iāll make it a HowTo if you have some success.
Sam
I have been unsuccessful getting VNC working with my Mac. I have a Raspberry Pi 3 with OSMC installed. Iāve installed dispman_vncserver. On my Mac I try to establish a VNC connection by going to the Connect to Serverā¦ window and entering vnc://10.0.1.15 as the Server Address. (Iāve assigned 10.0.1.15 as the fixed IP address for the RPi.) Apparently there is some communication between the Mac and the VNC server on the RPi but I never see a window for the RPI and eventually the connection request times out.
Has anyone ever gotten VNC to work using the default VNC client on a Mac and dispmanx?
Did you try that MacOS tip at the guide?
If you want to use OSX tool āscreen sharingā, start the vnc server with the password option:
Example
osmc@osmc:~/dispmanx_vnc$ ./dispmanx_vncserver --password=osmc
Maybe you need to open port 5900 and forward it to your pi first as well
What MacOS tip at the guide are you referring to, Sandbird? Can you provide a link?
I did try using the password option on the command line, and that didnāt have any effect.
I have port 5900 open for VNC already. I use Apple Remote Desktop and am able to use VNC to view/control my Macs. In my attempts to use VNC with the Raspberry Pi I have seen an error log file message reporting that the VNC server was using an outdated software version. (Sorry, I donāt remember the details.)
hmm, i havent used my hackintosh for quite some time nowā¦so i am a bit rusty when it comes to macsā¦but in this picture here you are why does it say 10.0.1.3 ? I thought your pi3 was on 10.0.1.15 ?
Lets try a few thingsā¦Back to the basics:
- If you set your pi to get an automatic ip address which address does it take? Is it in the range of 10.0.1ā¦? Did you try to let it have an automatic ip and try connecting to that first ?
- Do you have an iphone ? If yes, can you try downloading Vnc viewer and try connecting from there (before trying with more advanced tools like RD from the mac?
- Did you create a service for the vncserver ? I mean are you sure itās running ? IF yes, then do this:
systemctl stop dispmanx_vncserver
then manually start the server with :dispmanx_vncserver --password=osmc. You should be seeing this:
Now try to connectā¦(so we are sure the vncserver is running and listening for connections.
Why would you do port mapping if all your devices are on the LAN?
Thanks, guys, for the replies. With your comments I made some progress.
I installed vnc viewer on my iPhone and was pleasantly surprised to see that I was able to establish a vnc to my Raspberry Pi:
osmc@osmc:~/dispmanx_vnc-master$ ./dispman_vncserver

21/07/2016 16:43:15 Got connection from client 10.0.1.9
My home network has a couple Apple AirPort Extreme routers at 10.0.1.1 and 10.0.1.2. I have a Mac mini running Apple Server at 10.0.1.3. I have a number of devices assigned to IP addresses using their MAC addresses, and one of them is my Raspberry Pi at 10.0.1.15.
The screen snap showing Port Forwarding shows values established when I set up the Server software, and youāre right it shows the server IP address (10.0.1.3).
I need to educate myself a bit to see what I need to do to set up port forwarding for the Raspberry Pi. Sorry for my ignorance. Once I have done some reading I may be able to solve the problem on my own or at least be able to ask an intelligent question.
You ONLY need to mess with port forwarding when you are attempting to connect to devices from outside your home LAN.
@ActionA: If you use a Mac, then maybe you can explain why I canāt use the VNC client embedded in Mac OS. In the Go menu I select Connect to Serverā¦ and in the Server Address field I enter āvnc://10.0.1.15ā. In a Terminal window, logged into the Raspberry Pi via ssh, Iāve started the VNC server and I do see that it responds when I hit the Connect button after Iāve entered āvnc://10.0.1.15ā and entered the osmc password (āosmcā):

However, the cursor spins with āConnectingā¦ā and I never see an osmc screen":
I just noticed that when I successfully used VNC Viewer on my iPhone I get a message from the VNC Server that it connects using Client Protocol Version 3.8 but trying to connect from my Mac Iām informed that Iām trying to use Client Protocol Version 3.3. Maybe the Mac is using an outdated incompatible protocol to establish the VNC connection?
Yeah could beā¦i am not that familiar with mac os vnc apps, thats why i wanted to try with the iphone since i know that it works 100%. Well at least now we know where is the problem.
You could always try with : https://www.realvnc.com/download/viewer/macosx/
Realvnc works fine on the pc, so i guess it would work well on the mac as wellā¦Just need to tweak the āspeedā option firstā¦Cant go up to million of colorsā¦basic 256 colors connection will work fineā¦Anything higher and it the connection breaks. ā¦ Maybe thats what happens with your current mac app ? does it have any speed settings ? If yes try connecting with the lowest setting first.
ps: I got 4 pcs and 2 piās in my houseā¦thats why i keep specifying the ports because all of them are running similar servicesā¦but yeahā¦you dont really need portforwardning inside your lan, if you only have 1 pc/pi running vnc. Nonetheless when something is going wrong its a necessary step to find the culpritā¦so you know at least that portforwarding is not to blame here.
@Sandbird: vnc viewer worked on the Mac. It uses RFB protocol version 3.8, so maybe MacOSās use of the older version 3.3 is the problem. Anyway, thanks for the help.
I didnāt make it very far as shown here. Would someone please advise?

Hi Lucalobe , how you solve realvnc error ?
assertion failed one ā¦ its work on tightvnc ā¦ but i need it on realvnc :S
Works also on OSMC with Krypton without any errors
