General: Does Jump Desktop support adhoc wireless connections (i.e. Router-less connections)? General: Does Jump Desktop support Windows Home or Windows Home Premium? General: Does Jump let you specify alternate or non-default ports for RDP / VNC? See more Mac: How do I enable the VNC Server built into the Mac? I used to be able to use Apple's VNC server to control my Mac from a Windows XP machine using Ultra VNC. Now, Ultra VNC seems to establish a connection, but gets hung up drawing the first screen.

I regularly need to connect from a Windows box to an OSX box over VNC.
OSX has VNC built-in as part of its 'Screen Sharing' tool, but for some reason, it's much faster to connect from OSX to OSX or from OSX to Windows than it is to connect from Windows to OSX. (I use UltraVNC on Windows.) Windows to OSX connectivity is almost unusably slow, even when the two boxes are sitting right next to each other, plugged into the same router.
How can I improve performance in this case? Should I explore alternate Windows clients? Alternate OSX VNC servers? Should I use some other screen-sharing tool instead of VNC? (If so, what?)
(Note that this question is more specific than other more general questions.)

OS X Leopard with its own ScreenSharing client, connecting to another OS X native screen sharing server, does some negotiation on colour depth, etc., so it's transferring less data.
(You can see this effect exaggerated if you connect to an OS X system from Windows using the RealVNC client over a higher latency connection. It will take a long time to build up the screen output.)
I couldn't find a way to make RealVNC request a lower colour depth so what I did, to work around this, was run a copy of VineServer on OS X with the '-maxdepth 8' option (and '-rfbport 5901' to run it as an alternate server), and connect to that when I connect long distance (which I always do through an SSH tunnel, before anyone states the obvious.)

I've switched from UltraVNC (back) to RealVNC, primarily because UltraVNC was not handling my multi-monitor server right.

I found switching to Vine Server rather than the default Apple one made a huge difference to performance.

I experienced the same thing, but could not get UltraVNC or TightVNC to match the performance I expected. I was tipped of TeamViewer and it worked like a charm. The setup configured the computers for access and after letting them accept connections over LAN I got speedy remote control with full colours.

Mac Vnc Server
I use a Mac Mini as Home Entertainment System (no keyboard or mouse connected).
To access the Mac Mini from my Windows 7 PC I use VNC (note the Windows 7 PC has a German keyboard).
My problem is that I can't get the Mac 'Option-Key' to work. Googling the internet brought up the following tips (which did not olve the problem):
So I found the special keys configuration in the Mac system preferences > keyboard > special keys. Here I don't manage to make any settings since the remote keyboard (= VNC connection) is not recognised - the system state is 'no keyboard connected'.

In UltraVNC you can press the Scroll Lock key once. This allows you to press your Windows key and have it act like the Command key on OSX (it's in the same position too).

The answer is here:https://www.realvnc.com/products/vnc/documentation/5.0/misc/keyboard-mapping/
tl;dr
Opt key is mapped to AltR on US-PC kb and AltGr on non-US PC kb
If anyone knows, in general, how to access remote mac's option key from any client (say, the iOS VNC.app client, or Andriod's VNC client), plz post as answer to OP's question, tia.

Yes there is a virtual keyboard built into OS X.
Vnc From Windows To Macos
System Preferences > Keyboard > Show Keyboard & Character Viewer in Menubar [x]
Tightvnc For Mac
Then you will see an icon in the menubar, click on that and select 'Open Keyboard..'

I found nearly the same problems with Mac-Mini (late 2012), with Italian keyboard.
I've performed some tests with Event Viewer tool found into KeyRemap4MacBook software, by comparing events with the local keyboard and the VNC connected keyboard. I suggest to use it to find what is happening for keyboard related problems.
I've tried with the native VNC server installed in OS X 10.8.4 Mountain Lion, the one installed in OS X 10.6.8, with VineVNC server (v4.01) and RealVNC server (v5.0.6).
Here my most interesting findings:
In my tests the real events that are received by the server are always different from the local events of an attached keyboard. For example there is no distinction between left and right buttons when you are connected with VNC (for every client I've tested).RealVNC client version used is '5.0.5 Windows 64bit' on Windows 7 Professional.
About the 'no keyboard connected' error, I've not tried nothing but connecting a keyboard to the MacMini (when I'm remotely connected I need to have a real keyboard connected to the Mac Mini !).

probably unhelpful shot in the dark here, but does super/windows key not work? It seems like they would be equivalent. Or am i confusing it with the command key?
