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.
Click a section below depending on which OS X version you are updating.
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.

Updating your software in OS X Lion, Mac OS X v10.6, or earlier
Getting updates immediately
- From the Apple () menu, choose Software Update.
Apple menu in Mac OS X v10.6.6
- Software Update checks for available updates. In the Software Update window, select the items you want to install, then click Install. Usually, you should install all available updates.
- Enter an administrator account name and password.
- After installation is complete, restart the computer if required.
You can repeat these steps to see if more updates are now available. Because some software updates are prerequisites for others, you may need to repeat these steps several times to complete the software update sequence.Mac OS X v10.5 and later can automatically run Software Update checks in the background and let you know when an update is available for your computer.
Updating apps that were purchased from the Mac App Store
Software Update does not show updates available for apps that were purchased from the Mac App Store. To update your purchased apps, open App Store on your Mac, then click the "Updates" view at the top of the App Store window. This will show all available updates for apps currently installed on your Mac.
OS X Lion updates come from Software Update as, described above.
Hiding certain updates
Sometimes you may see an update in the Software Update list that you don't need. You can hide it if you want to.
Using standalone installers from Apple Support Downloads
Sometimes a standalone installer may be more useful than the automatic Software Update feature. Examples include when you:
- Anticipate needing the file again later.
- Need to install on multiple computers and need a portable file.
- Have a faster Internet connection available to you at another computer.
- Have no Internet connection on a computer that needs the update.
You can get standalone copies of many Apple software updates from Apple Support Downloads.
Carefully read the stated system requirements before using a standalone installer. Be sure to install updates in the correct order when applicable, or only on compatible computers when applicable.
Reference releases; update vs. upgrade
Mac OS X v10.1, 10.2, 10.3, 10.4, 10.5, 10.6 and OS X Lion themselves are not free updates, they are reference releases, also called upgrades. Reference releases can be obtained from the Mac App Store. See also Update, upgrade--what's the difference?
