Use the Mac App Store

- Click Updates in the toolbar.
- Update each app individually, or click Update All to install all available updates.
To find software upgrades instead of updates, use Search in the upper-right corner of the window. An upgrade is a major new version of the software. For example, OS X El Capitan is an upgrade from OS X Yosemite or earlier.
Or use Software Update
