I read the following informations from the apple discussion. Mac OS X 10.9 Mavericks, breaks the tradition, and is available free (subject certain license restrictions) for anyone from 10.6.8 through 10.8.5 as long as they meet the system requirements for 10.8.

Apple's latest update to Mac OS X, 10.11 El Capitan, is currently available in the for everyone to download and install. The new OS features for better multitasking, a cleaner Mission Control, smarter Spotlight, a way to mute Safari tabs playing audio, enhanced Mail and Notes apps, and more. If you have multiple computers that need the El Capitan upgrade, then a bootable install flash drive will make the process easier and faster, since the install file is over 6 GB in size (about than Yosemite was!) and could take some time to download on each computer individually. If you're going to use El Capitan on your only computer, you can choose to install it as a dual-boot system, that way you can easily switch back to Yosemite if you find out that you don't like the new OS version.

• Don't Miss: While there are to create a bootable install drive, I'm going to skip those long processes in favor of using DiskMaker X, which has recently been updated to work with El Capitan. Step 1: Download OS X 10.11 Installer Once you've downloaded from the Mac App Store, don't install it just yet—it will auto-erase the installation app you need if you do. Close out of the installation screen that pops up, then hunt for Install OS X El Capitan in your Applications folder to verify it's there.

Step 3: Delete Any Old Installers You May Have If you still have an installer for Yosemite on your hard drive, or an El Capitan developer ('Install OS X 10.11 Developer Beta') and/or public beta ('Install OS X El Capitan Public Beta') version, you should delete those first. They take up a lot of space anyway. Step 4: Choose Your El Capitan File Go ahead and open the app up and you'll see the following screen.

Click on 'El Capitan (10.11)' so DiskMaker X can automatically detect your install file in the Applications folder. Step 5: Get Your USB Flash Drive Ready (Optional) Before proceeding, make sure you have copied all of your important files from your USB flash drive to another place, because this process will wipe your flash drive and reformat it.

Also, make sure that your flash drive is 8 GB or more, because the installer file alone is over 6 GB. Update: While you need at least 8 GB free to install El Capitan, it might not be enough to make a bootable drive. So if you get an error saying there isn't enough disk space, you'll need to get a 16 GB or larger thumb drive. Step 6: Select to Use a Thumb Drive No matter what size thumb drive you're using for this, select 'An 8 GB USB thumb drive' from the next window. Again, an 8 GB stick might not actually be big enough, so you'll probably need a 16 GB or larger stick.
