First of all, OS X since Lion has been available from the Mac App Store making installation and upgrades almost painless. OS X Mavericks is free from the App Store and it’s an easier install than ever before. Unless you want to create a bootable installation DVD.
DiskMaker X Makes Disks
Enter the free utility DiskMaker X which makes building an install disk about as easy as it can be done.
There’s nothing magical about DiskMaker X, which probably accounts for the price tag (free). You still need to have a copy of the Mac OS X version you want to install.
DiskMaker X can be used to create a bootable drive from OS X Lion, OS X Mountain Lion, and OS X Mavericks.
All you need is to download the version you want from the Mac App Store.
This disk making utility uses AppleScript so it works (mostly) on Macs running OS X 10.6.x, 10.7.x, 10.8.x, and OS X 10.9.x. It works with OS X Mavericks though you’ll need OS X 10.7.x and higher to build a Mavericks installer.
How difficult is it to use DiskMaker X?
Yeah, that’s about it. DiskMaker X will search your Mac for the OS X installer download (from the Mac App Store; OS X Lion, OS X Mountain Lion, or OS X Mavericks), then begin the installation process.
What do you get when installation is done?
A bootable disk with your choice of the OS X version. That means a bootable external disk drive, or a bootable DVD disk, or a bootable USB flash drive ready to be used to install OS X on a Mac. This method is particularly useful for clean installs, or to install on Macs where network access is limited.
Not bad for free, huh?
