As you know, Apple releases a new OS X operating system every year, and the new OS X can only be downloaded via the Mac App Store (currently OS X Yosemite). The older versions of OS X are still supported by Apple, but it should be more difficult to download. My following tip can help you easily download and create USB installer for OS X – Yosemite, Mavericks, Mountain Lion, and Lion.
Before doing, you need to prepare 2 things:
- An USB – at least 8Gb or higher.
- A MacBook to run Disk Utility in OS X.
When OS X shipped on a DVD a good number of years ago, you always had the convenience of a bootable installer—an OS X installer that could be used to boot your Mac if its own drive was having. Every Mac operating system since Lion (OS X 10.7) has included Recovery Mode, a special boot partition that enables you to recover from catastrophic failures and problems. This can be used to install a fresh copy of Mavericks on your hard drive, provided you have Internet access. To use Recovery Mode, follow these instructions: Shut down your Mac.
