A countdown timer for the macOS Dashboard.
Timer is a widget for the macOS Dashboard for alerting after a set amount of time has passed. Just type an amount of time, click Start, and it will begin counting down. When it reaches zero, a sound will play and a notification message will appear in the top-right corner of your screen.
Hover your mouse pointer over Timer and click the small "i" to flip to the back side, where you can change various settings.
If you're running OS X 10.10 Yosemite or later, you may need to turn on Dashboard if it isn't on already.
(On OS X 10.9 Mavericks and earlier, the Dashboard is always on.)
Download Timer.zip from this page, then find it on your hard drive and double-click it to open it.
Right-click on the Timer widget icon and select "Open" in the menu.
(If you don't have a right mouse button, hold the "control" key on the keyboard then click the icon.)
Click the "Open" button to confirm that you want to install Timer.
Timer works on Mac OS X 10.5 Leopard through macOS 10.12 Sierra.
OS X 10.8 Mountain Lion or later is required for notification messages to be displayed.
