Description

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.

A disappointing

I'm disappointed, just because this app didn't do the one thing I wanted it to do. I don't like having the (hidden) Dock on the bottom of the monitor, and if it is on the right side I sometimes accidentally bring up the Dock in dealing with notifications. So I wanted to put the Dock on the left side, and hoped that this app would allow me to do this. In my case, I should explain, I keep my second monitor to the left of my iMac. But, although the app works as advertised, when put on the left side, the Dock still shows up on the left side of my second monitor, not my iMac. This is scarcely the developer's fault, I don't blame him at all. But I do blame the Apple Store. Since it does not permit demo versions (traditionally the heart and soul of the shareware industry), I had to purchase the app first and then discover that it's of no use to me. This experience cost me eight bucks and illustrates one of the major reasons I dislike the App Store. (Another reason is that a developer can't charge one price for new sales and another, lower one for upgrades for existing customers, so some developers are forced to charge absurdly high amounts for upgrades, BusyCal being a good example of this.) I'm beginning to realize how anti-consumer it is, and how urgently Apple needs to rethink its implementation. I think both customers and developers ought to steer clear of the App Store until Apple cleans up its act.

Great for dual displays

This is a great little utility for dual display setups. When I have an external monitor connected to my MBP I work primarily on that display since it is larger. This utility keeps my mouse pointer from getting lost. It also helps me hit the hot corners on side of the display that adjoins the MBP screen.

One shortcoming, and I can't tell whether it is a limitation of the software or of OSX in general, if you align the top of the two displays then you cannot hit the hot corner on that edge of the screen. Perhaps, when the tops of the two displays match OSX moves the hot corner to the end of the second display instead. I'm not quite sure. This was a minor annoyance with my 17" MBP because the resolution of its display was the same as the external monitor. Now that I have a 15" MBP the resolution is smaller and I can align the MBP display between the top and the bottom of the large display and can hit the hot corners on the primary display without issue.

Solved a nagging productivity issue

It would drive me crazy when I had to hover my mouse at just the right spot to make menus accessible, especially when using an app like Lightroom where you have to hover for a moment before the menu bar appears (in certain view modes). Since I use 2 monitors all the time, this is the perfect solution! Works exactly as advertised and a must have utility for Lightroom users with dual monitors.
