1. Replaced the hard drive on an old 2007 iMac. Previously had this machine running 10.11, with no issues. Downloaded the El Capitan installer from the webpage, and used the createinstallmedia command to make a bootable USB drive.
2. This is how to install Mac OS X 10.11 'El Capitan' on an unsupported Mac Pro. In this video, I use a Mac Pro 1,1 (that has been flashed to 2,1 firmware).
3. OSX El Capitan on a MacBook Pro. Photo: Dave Ottalini. While it might seem easy to just Google your request, it’s not always that easy. Thus, we offer a list of OS downloads (from the Apple website and beyond) so that you don’t have to go looking for them. Even tho Catalina is available via the App Store, we’ll include it here (as a link).
4. Questions or comments? Feel free to contact me at email protected Please take a look at the FAQ located at the bottom of this page as well.

Mac OS X El Capitan can be downloaded directly from the Apple website. The Beta version of the OS is available but the final version will be made available towards the Autumn season of 2015 as speculated by many Apple users. You can use your older Mac OS with the new El Capitan, all you have to do is to create a different partition for the new El Capitan if you have the Yosemite already installed. There are few steps you should consider in downloading the latest El Capitan and these are as follow.

Part 1. Preparing Mac Device for the Installation of Mac OS X El Capitan

Both Mavericks and Yosemite are easier to download and install on Mac devices, however, this is not the case with Mac OS X El Capitan. Just before you install the new Mac OS X El Capitan, you must perform few tasks to ensure that your Mac will be ready for the installation of the software:

• Check Your Mac - Check whether your Mac will be able to run the new OS X 10.11. Apple has provided a list of the Mac supported by the new Mac OS X El Capitan and if you are already running the Mavericks or Yosemite, the same lists may also apply to the El Capitan. You can also check this list on the “Will your Mac run Mac OS X” article on Apple website.
• Create Enough Space - Check that your Mac has sufficient RAM to run the software. You wouldn’t run into any hitches if your Mac device is listed on the acceptable Mac devices for Mac OS X El Capitan. Apple recommend that you have a minimum RAM of 2G, however, a minimum of 4G space of RAM is highly recommended. You will also need to delete some unnecessary files to create more space for the installation of El Capitan.
• Check Hard Drive Space - Make sure you have sufficient hard drive space for the installation of Mac OS X El Capitan. Yosemite will normally require a Hard drive space of up to 5GB , but the new El Capitan will require between 15g and 20gb of space on your hard drive for successful download and installation.
• Register - Register to access the Mac Apple store. You need to upgrade your Mac and get access to Mac Apple store for a small fee in order to get the most out of your Mac OS X El Capitan.
• Updates - Make sure your third party Apps are updated before installing Mac OS X El Capitan. You can simply launch App store and click on “Updates” on the tool bar if you want to update the apps you bought from Apple store. For other third party apps, you may need some manual updates from manufacturer websites to complete such updates.
• Backup Your Mac - Perform a backup before downloading and installing Mac OS X El Capitan- you need to protect your important documents and files, thus you may have to back them up somewhere before starting the download and installation process.

Part 2. Installing Mac OS X El Capitan Safely on Your Mac Device

You can install or upgrade to Mac OS X El Capitan as a dual boot partition. You may be able to download a test version if you register for the OS X Seed program from Apple, and you can also provide a feedback to Apple in order for the company to update the software before it is finally released. You can follow these instructions to install the Beta version of Mac OS X El Capitan. It is strictly recommended that you perform a backup before you begin this process. It is important you keep in mind that Mac OS X El Capitan is still in a Beta format, thus , not all your apps or programs will work on it.

1. Visit the Apple Beta software program page and log unto the page using your Apple ID. Simply click on “Enroll your Mac”.
2. Click on the download link that shows up, and enter the personal redemption code given to you.
3. Open the downloaded Mac OS X El Capitan software and preview the file in the Applications folder. Click “Continue” and then select “Agree”.
4. Click on “Install” and then enter your admin password. You're all set!

Part 3. Installing Mac OS X El Capitan Safely on an External Drive

You don’t have to install Mac OS X El Capitan on your Mac device, you can also install it on an external hard drive, most especially when you want to access the OS quickly. You can consider Thunderbolt drives which are similar to the internal drives on Mac, or you can simply use the USB 3.0 external drive if you don’t have the Thunderbolt on your Mac. You will have to format an external drive before installing Mac OS X El Capitan, this will help to install the Mac OS X El Capitan safely on the hard drive and at the same time the configuration of your device will not be changed.

Connect the external drive to your Mac device and make sure it is detected. Launch the Disk Utility tool ( go to “Utilities” and you will find it there). Choose the drive- it is located at the side bar.

Simply click on “Partition”. Make sure the partition layout reads “1 partition”. Name the partition. You can use a name like “Mac OS X El Capitan”. Click on “Options” and ensure that the Guide partition table is chosen, and then click on “Ok”.

Click “Apply'. Open the preview file from your Mac’s application folder. Click on “Continue”. Click on the “Agree” button.

Click on “Show all disks”. Simply highlight the “External Hard Drive” on which you have just install the Mac OS X El Capitan

Click on “Install”, and enter the admin password.

Introduction

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:

Dosdude1 Catalina Patcher

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

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.

Bugs

Note: Please provide a clear step by step procedure to reproduce the bug. Thanks.
