OS X: Updating OS X and Mac App Store apps
You can get software updates for OS X and apps from the Mac App Store. In Mountain Lion and Mavericks, use Mac App Store for OS X Updates.
Updating your software in OS X Mountain Lion and later
In Mountain Lion and later, software updates come through the Mac App Store.
Notifications that updates are available
Notification alerts inform you that updates are available.
- Click “Details” to open the Mac App Store and see details about the updates available.
- If present, click “Update” or “Install” to install software updates.
- If present, click “Restart” to install software updates that have already been downloaded, but require the computer to restart.
- OS X Mavericks lets you select a convenient time to install updates. Click “Later” to postpone updating for now. Click and hold the Later button to see additional options.
Tip: When you tell Mavericks to “Try Tonight”, OS X installs available updates between 2 a.m. and 5 a.m. Your computer automatically restarts as part of the update process if needed. The next morning when you log in, your apps and windows re-open just the way you left them. This way your computer is up to date, and ready to pick up where you left off.
You may see a badge appear with the number of software updates available on the App Store icon in the Dock.
