1. Download Yosemite from the Apple Store

Yosemite can be downloaded directly from Apple Store here. After download it will try and install automatically on your Mac. Just cancel out of this.

2. Verify the Installation Files are present

Head over to your Applications folder and check that there is a file which says Install Yosemite

2. Prepare a USB Flash Drive (Must be 8Gb or larger)

• Plug the USB Drive in to your Mac and open “Disk Utility” (found under applications / utilities in finder)
• Select the USB Drive
• Select the Erase tab
• Ensure that the format is Mac OS Extended (Journaled)

IMPORTANT – Leave the name as “Untitled”. If you change this the next step won’t work

3. Create the Bootable Yosemite USB Drive

Open up Terminal (found in applications)

Type this in:

Wait for the process to complete. Done.

4. Boot from the Yosemite USB Drive

Create Yosemite Usb Installer Mac
