Lion broke screen sharing, VNC?

Lion is installed fine and dandy on my iMac. However, I cannot use Screen Sharing from my laptop (not upgraded... Yet) nor can I use VNC from my PC or iPad to connect to the iMac. Everything gets a "could not connect" error with no useful information.


I have Remote Administration turned on with thiMac and could use VNC just before the Lion upgrade went in.


Any pointers/suggestions?

iMac, Mac OS X (10.7)

RealVNC Server will indeed reconnect as Apple used to up to 10.6.8, but the keystrokes don't match. On iOSProApps Custom Keypad app for example under Apple VNC, it works perfectly while still connected, but under RealVNC, Cmd+Shift+i is sent as just 'i'


What is a fantastic and powerful tool (still) under MacOS 10.6.8 becomes Roadkill from Lion 10.7 onwards.


Apple HQ is a mess these days, VNC is but one of the symptoms.

Thanks William. Is there any official word on this? I'm yet to find anything. Where did you find this out, can you link me there? This is a no go without evidence as the buck will stop with me, not Apple. I'm not about to go there!


Also I hear Mountain Lion breaks existing Wikis and Users, something I'm keen to disprove, as my client has a wiki on Snow Leo at the moment.

In a corporate enviroment, where there are older machines, that wont be able to upgrade to Mountain Lion.

An 20$ upgrade is not going to solve this problem. There should be a fix to this rdm problem. We upgraded to

Lion, and some of the clients cant upgr to ML ...

So no remote desktop support for Lion clients without hassle?


This screen is quite often what you get when connecting to a client computer:

Sorry Enthususast.


I too work in a large enviroment, but it is primarily Windows. The few Macs i support are upgradable to ML. The issue with Lion has been onging and in my opinion Apple wiil not address it as another means of encouraging upgrades to ML. Apple has never been sensitive to backwards compatibily and that is why we shy away from it in my organization. just wanted to put out there that it works on ML.

Someone needs to start an Apple lobby group so those of a mind to, can bring the power of our numbers to bear against Apple when it breaks things and doesn't fix them afterwards. We expect more from a child than we are expecting from the world's biggest Wall St success.


There are millions of us, against a handful of board members, drowning in gold, so how has it come to pass that they can they repeatedly win against us like this? It's time for us to get emails going to the board members, and faxes to make them sit up and take notice.


If we work together, we can force Apple listen to us.

A fix on Mountain Lion ? WOW .. that would be great. BUT, my Quad Core Intel Xeon Mac Pro is not able to upgrade to ML. Considering it's more powerful than half the machines that are able to upgrade, it's clear Apple is restricting ML for arbitrary (and not entirely technical) reasons.


Can someone confirm what the "fix" is and if it might be a binary (or something) that can be added/run on Lion or do I have to continue to deal with a third party VNC server workaround (which happened to also crash on me so now this system is completely inaccessible to manage until I get back in town and can physically touch it later this week) 😟

I have Mountain Lion (10.8.1) installed, and still have intermittent but regular issues connecting remotely, either via Mocha VNC on iPhone/iPad using the "Mac OS X Lion sign on" over 3G, or UltraVNC for Windows at work (on a big fat pipe).


For me, it appears data gets garbled during the authentication process, according to a quick glance at a recent console log (if you can see the gist of what’s happening in this tiny screenshot)…

DW, just a thought but try wyse pocketcloud app for your iPad -- while I haven't tried against mac os x lion machines, I have used consistently against windows on my iPhone. (I know different animal, but might be worth a shot).

Keeping an eye on this thread though, as I'm looking to get a mac os x lion desktop for remoting into.

I have some users which were not granted permissions to do remote management, while one of their accounts was open I noticed an error stating that they were not authorized to use Ardagent. This occured even though under Remote Management the option to permit all users was selected. I have revoked the general permission and now explicitly granted each known user permission. I need to observe the machine longer to see if this helped the vnc issue I am having. I am mac to mac vnc with Jolly Fast Home from the app store or screen sharing.

-This thread has 90000 views but still no solution for Lion?


-Is it true that Lion incorporated a secure non standard VNC protocol to increase safety that broke all non VNC clients from connecting to it or could there be another reason?


-Can anyone else confirm that Mountain Lion's builtin VNC server is working when connecting from a windows VNC client like realvnc , uvnc , tightvnc etc... ?

Lion broke screen sharing, VNC?
