EdgeCase improves your multiple monitor productivity by restricting your mouse cursor to a single screen.

The app prevents you from ever accidentally losing your cursor into a rarely-used secondary display, or from overshooting as you flick to an OS X hotcorner or the menu bar.

When you do want to switch to another screen, EdgeCase provides several shortcuts that allow you to cross screen edges manually. Simply perform a 'bounce' gesture, wait for ½ second, or hold a hotkey. Your cursor will then move into the next screen freely.

> "I’ve found EdgeCase to be useful on my multiple-display setup." - Dan Frakes, Senior Editor at Macworld

> "A pretty good solution to this problem." - Marco Arment, Creator of Instapaper (dot com)

> "Once you have more than one monitor, instead of hitting the edge, the mouse moves to the other screen. EdgeCase solves this problem. With EdgeCase, the edge returns, and works as if you only had one monitor." - Lukas Mathis, Ignore the Code

EdgeCase prevents your mouse from moving between multiple monitors by putting a temporary barrier between the edges of your screens.

EdgeCase makes it easy to work with a single screen. It's better than closing your Mac laptop (aka clamshell mode) because running your laptop while closed leads to increased heat and fan output.

- You will never accidentally lose your cursor in a secondary monitor.
- Hot corners are easier to hit.
- Easily click on scrollbars or other widgets located on the edge of the screen.
- Never "overshoot" the Spotlight or Apple menus again.

When you do want to move your cursor into the secondary monitor, there are several crossing shortcuts:

- Bounce your cursor on the screen edge.
- Hold [ctrl] or [⌘].
- Wait for ½ second.
- Cross when dragging.

The barrier will unlock and your cursor will cross into the other monitor.

EdgeCase is an unobtrusive menubar app that works in the background. Click the menubar icon to access the app's options. Turn the crossing options On/Off, or temporarily disable the app.

"Inverse Hotkey" mode. EdgeCase's evil twin: cursor is bounded only when holding hotkey.

Option to use EdgeCase only on your main menu bar screen. Allows uninterrupted crossing from a secondary screen back to the main screen.

New menu bar icons for "Inverse Hotkey" and "Disable EdgeCase" modes.

New global keyboard shortcut ^⌘E to toggle "Disable EdgeCase" mode. Turn EdgeCase off temporarily, on the fly.

The "Bounce" and "Wait" crossing gestures are now easier to perform.

No more hunting for the little cursor - This app has helped me never lose track of my mouse. Things can be hectic when dealing multiple monitors and fast flicking gestures. I appreciate this small app. It was done very well - no annoying dock icon (runs completely from the menu bar) and very nice transparent menu for configuration options. Thanks!

Review by EliPC

Very unpolished, not worth $5 - With fast movements the cursor will bounce but often flash inelegantly on the other monitor. This sometimes results in "stray" edge cursors left on the screen until you restart the program! Doesn't work with Synergy multiple monitors. Another usage scenario, more appropriate to my workflow is NOT supported: have the cursor bounce ONLY when I press, say, the CMD key, then and only then bounce. That would allow you to flick quickly to a side or a corner when you need to but move around from monitor to monitor most of the time.

Review by Swammy456

Perfect! - I have 2 external monitors; one each side of an iMac. I only use the 2 external when I really need to, which is typically only a few times a week. Even when these monitors are turned off, the mouse in OSX can still wander onto them. I also use hot corners for certain things. It’s annoying to need to drag the mouse across large un-powered screens to activate a hot corner. This app solves both of these problems for me. The mouse now stays put on the iMac until I need the other monitors and hot corners function like they should, at the corners of the iMac not the external screens. Exactly the app I was looking for! Well worth the cost for my use. Working fine on Sierra 10.12.1.

Review by Beaver2 1 2 1

Garbage - Does not work at all. I thought it was working at first, but then I noticed that the mouse still goes up into my second monitor. It will shoot up into the second monitor randomly and if you are clicking when this happens it will open programs or mess with settings etc… It is extremely annoying and makes the app worthless.
