All you need to know about preparing your Mac to install Apple’s new OS X El Capitan
Apple’s newest operating system for Mac OS X El Capitan will be available as a free upgrade from Wednesday September 30, following several beta versions throughout the summer.
Historically, Apple tends to seed these releases around 18:00 BST, so keep an eye out for an update round about then, which we expect will require around 6GB of space to intstall.

How to download El Capitan
- Ensure you have at least 6GB of free space
- Back up your computer before going any further, using Time Machine or similar
- Make sure you are running OS X Snow Leopard or above, ideally Yosemite. Click the App Store logo in the Launchpad and then Updates to check if you need to make any changes. Click Update All to make sure all apps are also running smoothly.
- Once El Capitan is available, you’ll be able to download it from the Mac App Store. This is likely to take several hours.
