El Capitan Unsupported Mac

If you have a mid 2009 MacBook Pro, you can't update the OS. To update, you need a MacBook Pro (Mid 2010 or later) Model 6.2 and higher.

El Capitan can run on these A1181s, but they're only supported for the 2009-2011 A1181s (MacBook 5,2). It's a shame that the 5,2s are quite hard to find (in my experience). I still use a 2007 A1181 and that keyboard is a joy to type on, a far cry from the god awful butterfly keyboards. 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). If your Mac isn't compatible with the latest macOS, you might still be able to upgrade to an earlier macOS, such as macOS Catalina, Mojave, High Sierra, Sierra, or El Capitan. 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.

A list of supported scanners for OSX 10.9 Mavericks can be found here. Here’s a quick step-by-step instruction: – connect your scanner directly to your Mac using a USB.

If you are careful about what you download and where you search on the Internet, your computer is useable without the latest security updates. My last computer had a 10.6 partition which I used every night. That was after El Capitan was released, so the OS was 5 versions behind. By being careful, I never had any problems.

I would make sure that you had at least 2 separate backups on 2 separate drives in case you have problems. That will allow you to recover.

El Capitan On Unsupported Macbook Pro

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:

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.
