Firstly, have another user to your normal one that has the relevant screen sharing options allowed, then login: To use the virtual display, here's what you need to do. This was an easy thing to use on 10.7 but it's been obfuscated rather on 10.8 and the menu item command to switch displays is gone. Using normal screen sharing you have the option of using either the hardware display, or the virtual one. OK, I cannot comment on using ARD, I don't have it, but this may be a suitable workaround, at least in the meantime. Either way, it seems like the solution should be the same. I'm not sure what I'm doing to trigger this situation, but I'm definitely not logging out.
#How to escape full screen mode on a imac desktop computer mac#
This will leave the Mac inaccessible to the Remote Desktop app and even a physical user of the computer, with the large lock icon still on the screen of the target Mac. One way to reproduce this: Log in to the target Mac with Remote Desktop, initiate Curtain mode, and then after finishing whatever work was to be done, log out the user on the target Mac while still under Curtain mode. My question: is there a way to successfully unlock a Mac that's stuck on the ARD lock screen, using ssh or otherwise? to tell all my running applications to gracefully quit, then I run shutdown -r now to reboot the machine. Eventually, I resort to using osascript -e. None of these things seem to unlock the screen. I've tried killing the ARDAgent process, the screen lock process (I can't recall the name), and anything else I can find with "ard" or "remote" in the process name. I usually try ssh-ing into the Mac from another machine and killing processes. Despite now being physically present in front of the Mac, I can't find a way to unlock the screen. (Latest ARD and OS X 10.8.2 on both machines.) When this happens, I come in to work the next day to find the big lock icon and message on my Mac's screen. Unfortunately, there's a bug of some kind that causes the remote Mac's screen to stay locked, even after I've disconnected from it. My work Mac's screen shows a big lock icon and a message while I'm remotely controlling it from my home Mac using Apple Remote Desktop (ARD). I use this when I connect to my work Mac from my home Mac. Apple Remote Desktop has a "curtain" feature that a remote client can use to lock the screen of the Mac that's being remotely controlled.
