This question is **NOT** a duplicate of the question How can I use Windows to create an OS X El Capitan or macOS Sierra USB flash drive installer from the disk image (.dmg) file downloaded from Apple? -- Here is why: >The InstallMacOSX.dmg file for Yosemite, which can be downloaded from Apple, uses the Apple Partition Map (APM). The The InstallMacOSX.dmg files for both El Capitan and Sierra, which can also be downloaded from Apple, use the GUID Partion Table instead of an APM. The Paragon Partition Manager Community Edition 64bit does not recognize APM. **Therefore, instructions for creating an USB Flash drive installer for El Capitan and Sierra can not be used to create an USB Flash drive installer for Yosemite.** This is why I wrote both questions and both accepted answers! -------- There are many posts on the Internet where instructions are given for creating OS X USB installers by using the TransMac and other such applications on a Windows machine. Many of these posts assume one is starting with a disk image (.dmg) file made from an existing OS X USB flash drive installer. An InstallMacOSX.dmg file for OS X Yosemite , can be downloaded from the Apple website How to download macOS . While this file can be restored to a flash drive, the result is not a working OS X Yosemite USB installer. >Note: This answer for Mavricks and this answer for El Capitan do not work for Yosemite. How can I use Windows to create an OS X Yosemite USB flash drive installer from the InstallMacOSX.dmg file for OS X Yosemite, which can be downloaded from Apple?
