Install updates automatically
OS X Yosemite can install updates automatically as they become available in the Mac App Store. Click Turn On in the “Turn on Always Update?” notification, which appears the first time an update is ready. Or turn on automatic updates in App Store preferences: choose System Preferences from the Apple menu, then click App Store.
If your Mac needs to restart to install, it restarts overnight, then re-opens your apps and windows as you left them.
Install updates manually
In OS X Yosemite, updates that haven't been installed produce a badge next to App Store in the Apple menu, a badge on the App Store icon, or an App Store notification. You can use the App Store notification to install the update now or be reminded to install it later.
Or open the App Store and click Updates in the toolbar. OS X updates appear first, followed by app updates, then updates installed in the last 30 days. Update each app individually, or click Update All.
If your Mac doesn't have the App Store app, choose Software Update from the Apple menu, then follow the onscreen instructions.
You can also get certain updates from the Apple Support Downloads site. These standalone updates can be useful if you want to install the same update again or on another computer. Read the update's description to learn whether your Mac can use the update or you need to install other updates first.
- You can resume interrupted downloads in the Mac App Store, hide or unhide purchases, and get apps that were bundled with your Mac. You can also get the latest version of Safari.
- If you're on a business or school network and aren't getting software updates, check with your network administrator. Your institution might be using a proxy server, which needs to allow secure connection to Apple's software-update servers.
- If you're using an iPhone as an Instant Hotspot, install updates manually. Your Mac doesn't get updates automatically when using a cellular data connection.
