This method involves using a free Application called DiskMaker X. And what separates this method from the other methods that I wrote about is that this is incredibly simple.
#1 – Download OS X Mavericks
First things first, you need to download OS X Mavericks. This is a FREE download from Apple. Here’s link to it: OS X Mavericks
Next thing you need to do is download and install DiskMaker X
#2 – Make a Bootable USB drive with DiskMaker X.
Here’s a quick chart that I whipped together to show how incredibly simple it is to make a bootable USB drive for Mavericks with DiskMaker X.
- Once you open DiskMaker X you’ll be asked which version of OS X you want to install. Choose Mavericks.
- Next, DiskMaker X will scan your Applications folder for Mavericks. (When you download Mavericks from the App Store it will automatically be downloaded to your Applications folder.
- Make sure you USB Flash drive if plugged into your Mac. DiskMaker X will automatically find it.
- If you have more than one drive hooked into your Mac, you’ll be given the choice of which drive to install the Mavericks setup files on.
- Everything on the USB drive will be deleted so make sure there isn’t anything on it that you want to keep.
- Formatting the USB drive requires your password.
- Enter it and click the “OK” button.
- DiskMaker X will now start coping over all the required files. This can take quite a while since there will be Gigabytes of data being copied over.
- Congratulations you just created a working bootable copy of OS X Mavericks.
Now there are two ways of booting into the USB.
Choose one method:
1. Open System Preferences -> Startup Disk -> Select the USB drive -> Click the “Restart” button.
2. While your Mac is restarting hold down the “alt” key on the keyboard and select the USB drive.
