How do I exit full screen mode in Screen Sharing?

I had the same issue. And for me it was resolved by simply hovering in the top of the screen for a bit longer. Eventually the menu bar appeared with the possibility to exit full screen mode.

No, I don't think that's how it is supposed to work.

I don't have a Snow Leopard system at the moment to use as a test target, but I can screen share into a Lion system from my MBP running Mountain Lion, put Screen Sharing into Full Screen on the MBP, then get the MBP menu bar to pop back up by putting the cursor at the top of the screen. Is that what is not working for you?

well I jammed the cursor at the top for minutes and couldn't close full screen when screen sharing my macbook air on my imac (both OSX10.8.2). only way out I cou,d get was force quite... Can't be right!!! any help gratefully received.

I found that on my Mac Pro dual display setup, the cursor has to be moved to the top of the screen on which the full screen mode was initiated. My OSX menu is on my left monitor. When the screen sharing application has its window on my right monitor on the moment I enter fullscreen mode, the left screen is used to display the remote computer and the right monitor is greyed out.

Moving the cursor to the top of my left monitor has no effect, even though my local OSX menubar is there, "behind" Screen Sharing and regardless of where the Screen Sharing is displaying its content at that moment.

Moving the cursor to the right screen makes all the difference.

Weird, but good to know.

polycorpmedia and gein are both right.

You have to move the cursor to the top of the screen on which Screen Sharing is running, AND you have to hover there a LOT longer, it seems to me like more than a second.

It's weird and inconsistent, Apple should fix this.

The reason why it seems impossible to exit full screen is that it is running in another workspace. The screen sharing menubar that should be activated when you move the mouse to the top of the screen is buggy.

If you have a trackpad, use a three-finger left or right swipe to move back to your local workspace (ie your local computer). Then close screen sharing via the dock icon.

Great finding, xcorlett!

If one doesn't have a trackpad with gesture capability one can try to hold down ctrl and press left (or any of the arrow keys) to switch back to the other workspace. This should work unless the shortcut has been disabled in System Preferences > Keybaord > Shortcuts.

There is a keystroke combo that I remembered trying a thousand times for Thunderbolt, it worked like a charm

Opt+F2, it immediately moved back to the main desktop, when I go back to screensharing, it instantly fills fullscreen again.

Opt+F2

Martin's suggestion is great for those of us who toggle frequently between the remote and local screens during a screen sharing session. Using a keystroke (or swipe) to toggle between screens is much easier than non-full screen mode in which you must click outside the screen sharing window to return to your local screen.

Thanks Martin & xcorlett!

It's been a while, but I thought I'd add to this. I frequently have this problem when I have multiple full-screen screen sharing sessions (and use a lot of ctrl-left/right)

This is a little worse because sometimes you want to close one without exiting screen sharing; and you don't want to just leave it around.

I found that sometimes the menu bar is associated with one of the sessions not currently on screen. If I toggle my active session and go to the top, one of them will always activate and pull down. At that point it seems to be 'fixed' and I can go back to the full screen space I wanted to close.

Does it work for you when you run other applications in full-screen, or it just Screen Sharing that isn't showing the menu bar?

this worked for me.

Right, the cursor has to be jammed clear into the top of the screen.
