Updating the OSX Yosemite Installer
Before you begin it is best to use the latest OSX Yosemite installer which is currently at 10.10.3 Build Number 14D136, download it via but don’t install, the installer location will override the previous installer, the dialog box that opens after you click download confirms if you wish to download the full installer, which you do.
