Mountain Lion - Screen share over WIFI

I want to keep my headless Mac Mini with Moutain Lion. I was wondering if there was no other solution to share a screen than a VNC base protocol that would not have the probleme of the screen connected....

As soon as the screen is connected I am quite happy about Share Screen. So my question is how to fix it (I do not want to simulate physically a screen with a dongle or stuff like that) ?

Will you report the problem to Apple as they invited you to do ?

Thanks

Ha they just removed another post of mine, funny it was just a copy paste of the email Apple sent me hahahah, what a load of crap.

It cant be fixed mate, I have tried everything, just make a simple dongle with a display port to VGA adaptor and a couple of resisters, this is what I did, there to slow to fix important stuff like this issue, but there not slow howerver at removing my posts.

Ill probably get banned soon for speaking "too" freely

Also there was a file I edited to allow me to select a wide range of resolutions as well, it doesnt help much as the higher the resolution the lagier it appears to get, so best results are low res and a screen attached or a dongle attached, doesnt matter if your conected via WiFi or Lan, its still not very good, both appear to be the same from my experences

Lan or Wifi does not matter I agree.

I have already my TV connected when I use my Mini Mac for video and I do not want to add a dongle permanently....

I reported the bug to Mac Mini Team as they advised... Please report also...

I will wait for the fix; I am sure it will happen. Mac Mini headless is one of the reason people buy the Mac Mini so there is no way they will ignore it.

I would not mind a slow refresh; my problems are more the bug that that slow behaviour is generating.

Anyway thanks for your help !

I have reported it, just gets ignored I think, also how is your TV connceted? is it HDMI? is there an auto mode for the HDMI, on my TV if I turn this Auto mode on, it sends a signel when you turn the TV on or off, this in turn will switch the source on or off (provided this feature has bee enabled)

My point is have you looked for or tried to disable/enable this feature? if its turned off the MAC Mini may still see the TV attached even when the TV is powered off?

I have a PC conected to my TV and if this feature is enabled and the TV is off the PC wont see the TV attached, but if this feature is disable and the TV is turned off it does see the TV.

Have a look and see if there is any features on the tv that may help keep its signel alive whiled powered off

Another one that improved my TV is switching the HDMI mode to PC mode on the TV, I think this turns off frame packing and some other stuff, makes the TV behave more like a computer monitor.

I have not found this option...

I will wait for a fix; honnestly it should come soon !

Apple uses a bug reporter tool at bugreporter.apple.com. Have you tried submitting this bug there?

This is for developper.

I went to

http://www.apple.com/feedback/

Anyway Apple should be aware of. Thanks

Has anyone tried a different VNC server?

Like Vine Server 4.01 available at http://www.testplant.com/support/downloads/vine/

Turn off Screen Sharing or Remote Management in Sharing prefs and launch Vine Server and see if it helps or not. I'd really like to know.

Yep tried that, exactly the same, every VNC server/client I have tried has latency issues on ML, I gather its something to do with the OS and not the server/client that's being used, I tried every VNC setup I could find, nothing seems to change, on that note I do prefer Apples screen-share over the others due to ease of use and being more reliable, drag and drop from one Mac to another is a cool feature, something that I think is better than RDP.

I have now scrapped the whole screen sharing and have placed my Mac Pro server on my desk with a second hand cinema display and packed my Macbook and thunderbolt display away, remote desktop is just way to slow and visually poor to use, Id rather use my server as a desktop/server now, I just wish I had purchased a 27" Cinema display instead of a thunderbolt display, I cant use this with a Mac Pro.

If (hopfully when) Apple fix it I will change back to my previous setup but until then if you want to do any serious work on your mac server (Mac Mini or Pro) best to plug straight in and use it if possible (I know its not choice everyone can make).

Hello

Eventually I solved the problem by buying an EDID emulator so I do not have to plug any screen or TV when using Share Screen and Share Screen works pretty well like that.

It is working very well but I still hope Apple can fix this bug (is it really a bug)...

We have solved similar issues on three Mac Minis and one Mac Pro by building a video dongle as explained here: http://blog.macminicolo.net/post/33839671756/build-a-dummy-dongle-for-a-headless -mac-mini

I'm also running a headless setup. Screen sharing became much snappier after changing the resolution in the "Displays" pref-pane to "Best for built-in display" (from previous "Scaled") on my headless Mac Mini.
