Yosemite Os Installer

A Guide for the creating of a patched OS X 10.10 Yosemite Installer for unsupported older Macs: Prerequisites: - get the 'Install OS X Yosemite.app' from Apple's App-Store ('OS X Yosemite Installation' in Mac 'Applications' folder) - make a BACKUP of your System if possible - get a USB-Flashdrive (8 GB or more) or use a external Hard Disk Drive. The El Capitan installer is downloaded to the /Applications folder, with the file name Install OS X El Capitan. If you have already installed El Capitan and want to now create a bootable installer, re-download the installer from Apple.

To get the latest features and maintain the security, stability, compatibility and performance of your Mac, it's important to keep your software up to date. Apple recommends that you always use the latest macOS that is compatible with your Mac.

Check compatibility

Yosemite mac os installer

The version of macOS that came with your Mac is the earliest version it can use. For example, if your Mac came with macOS Big Sur, it will not accept installation of macOS Catalina or earlier.

If a macOS can't be used on your Mac, the App Store or installer will let you know. For example, it may say that it's not compatible with this device or it's too old to be opened on this version of macOS. To confirm compatibility before downloading, check the minimum hardware requirements:

  • macOS Catalina 10.15 hardware requirements
  • macOS Mojave 10.14 hardware requirements
  • macOS High Sierra 10.13 hardware requirements
  • macOS Sierra 10.12 hardware requirements
  • OS X El Capitan 10.11 hardware requirements
  • OS X Yosemite 10.10 hardware requirements
