Check compatibility
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 might say that it's not compatible with this device or is 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
Download macOS using Safari on your Mac
Safari uses these links to find the old installers in the App Store. After downloading from the App Store, the installer opens automatically.
- macOS Catalina 10.15 can upgrade Mojave, High Sierra, Sierra, El Capitan, Yosemite, Mavericks
- macOS Mojave 10.14 can upgrade High Sierra, Sierra, El Capitan, Yosemite, Mavericks, Mountain Lion
- macOS High Sierra 10.13 can upgrade Sierra, El Capitan, Yosemite, Mavericks, Mountain Lion
Safari downloads the following older installers as a disk image named InstallOS.dmg or InstallMacOSX.dmg. Open the disk image, then open the .pkg installer inside the disk image. It installs an app named Install [Version Name]. Open that app from your Applications folder to begin installing the operating system.
- macOS Sierra 10.12 can upgrade El Capitan, Yosemite, Mavericks, Mountain Lion, or Lion
- OS X El Capitan 10.11 can upgrade Yosemite, Mavericks, Mountain Lion, Lion, or Snow Leopard
- OS X Yosemite 10.10can upgrade Mavericks, Mountain Lion, Lion, or Snow Leopard
Introduction
El Capitan Patcher
This project is a new and updated branch of the Yosemite tree and is targetted at OS X 10.11 El Capitan with SIP support, automatic installer detection and fake board-id injection for unsupported models of the MacPro and MacBook Pro.
Download
All downloads of boot.efi should be done from this project page. All other sources are unsupported.
Download your copy of the prebuild (32-bit) version of boot.efi for El Capitan (compiled on Microsoft Windows 10 with Microsoft Visual Studio 2015) with a black background and white Apple logo now, and verify the download by entering (either one) in a terminal window:
Or download the one for legacy hardware, with a grey background and logo for your Mac Pro and verify the download by entering (either one) in a terminal window:
Note: If the output is different, then your copy of boot.efi should not be used!
Compilation
Don't want a prebuilt copy of boot.efi then compile the source code yourself, with either Microsoft Visual Studio 2013 or 2015. The latter requires you to update the solution files, but that should be done automatically in the MS Visual Studio IDE.
Note: See also Compiling-Instructions
Thanks To
Dosdude1 Big Sur
This project would not have been possible without the help of Peter Holbrook, Mike Boss and a number of other people. Peter did all compiling and Mike ran dozens of test builds that Peter pushed out over at forums.macrumors.com Awesome work guys. Job well done!
I'd also like to thank everyone else whoh helped with testing our nightly builds. Thank you so much!
Help
If you need help with the setup then please visit this macrumor thread. Developers, or people who need help with compiling boot.efi themself, can visit this macrumors developer thread.
Note: I myself don't own any unsupported Apple hardware with a 32-bit EFI implementation, so I can probably do not much for you, but there may be others to help you.
