MacOS Sierra (version 10.12) is the thirteenth major release of macOS (previously Mac OS X from 2001 to 2012 and OS X from 2012 to 2016), Apple Inc.' S desktop and server operating system for Macintosh.It was the first version of the operating system issued under the June 2016 rebranding as macOS. Sierra is named after the Sierra Nevada mountain range in California and Nevada. It sounds like you have a mac pro 1,1 like mine with Quad core 2.66GHz processors. It is correct about the 32 bit EFI on these systems but there is a workaround with a re-written bootloader for the MacPro 1,1 that will enable you to run El Capitan (last OS before Sierra) flawlessly on your Mac Pro.

Apr 27, 2017 Looks like my Mac Pro is too old for macOS Sierra. I could have just done a search on iMore to discover that the cut off date for Sierra on Mac Pros was 2010. Never give up! Not to be deterred, I found a number of tutorials on how to install Sierra on an unsupported Mac! This involves disabling SIP or System Integrity Protection and makes your Mac less secure. Jul 01, 2016 I too have a similar Mac collection - G4 Sawtooth and Performa 6200 are in the attic now though. Mac Pro 1.1 (2.1) with new CPUs and El Cap will probably be around for a while unless it breaks, as Adobe CS6 in likely to start misbehaving on the newer OS and I.
Stay safe
In essence, High Sierra took what was good with Sierra and developed it into a more comprehensive software.
High Sierra emphasizes the already-existing benefits of MacOS previous system, Sierra. There are few bells and whistles, but the changes are noticeable and positive. The Apple file system is the most significant feature it brought. It enables the storage and encryption of a large number of files. Thus, it boosts performance and helps manage device memory issues.

Apple also introduced new formats for video and photos in this version. These formats compress data - that’s a benefit as files can get huge with ever-rising resolutions. They added support for virtual reality headsets as well.
Besides that, when it comes to Safari, Mac search engine, there are some notable improvements with the update. The users can now control annoying auto-play videos, prevent tracking, and more. There are also notification controls, and you will experience a boost in performance, too.
The most noticeable changes took place in Apple’s Photo App, though. It went through a total revamp both visually in its interface and terms of tools and functions available. Many other discreet changes happened all over the system.
Where can you run this program?
If you’re running Sierra on your Mac, you will be able to run this one as well.
Is there a better alternative?
Yes. Mojave, the newest version of MacOS, brought even more improved features to the table. However, if you can’t run it on your device, this is the second best.
Our take
High Sierra is not the shiniest upgrade Apple brought, but it’s one that sets the stage for new upgrades to come. Even out of that context, it’s a great operating system.
Should you download it?
Yes, if your device can support it. The new options and better security settings are worth getting.

Things you'll need:
- A copy of the macOS High Sierra InstallerApp. This can be obtained from the Mac App Store using a machinethatsupports High Sierra, or by using the built-in downloading feature of the tool. In the Menu Bar, simply select 'Tools > Download macOS High Sierra...'
- A USB drive that's at least 8 GB in size
- A copy of the tool - Download here (Current version: 2.7.0, SHA1: 73f180d30200ef5f6d900440fe57b9c7d22bd6bf)
-- View changelog and download older versions here
Known issues:
- Trackpad (MacBook5,2 affected only). The trackpad in the MacBook5,2isn't fully supported in High Sierra. While it works and is fully usable,High Sierra detects it as just a standard mouse, preventing you fromchanging some trackpad-oriented settings.
How to use:
1. Insert your desired USB drive, open Disk Utility, and format it as OS X Extended (Journaled).
2. Open the 'macOS High Sierra Patcher' tool, and browse for your copy of the macOS High Sierra Installer App.
*Ensure that the tool successfully verifies the app.
3. Next, select your USB drive in the Target Volume list, and click 'Start Operation.'
4. When the operation completes, boot your target unsupported Mac offthe USB drive you just created by holding down the Option key while turning on the machine, and selecting the drive.
Note: Only perform steps 5 and 6 if you intend to do a clean install.Otherwise, you can simply skip these steps and install to your volumecontaing a previous version of OS X, and it'll do an in-place upgrade.
5. When the installer boots, open Disk Utility from the Utilities menu, or by double-clicking it in the Utilities window on the bottom left corner of the screen.
6. Select the disk or partition you want to install on, and erase it,ensuring to use either Mac OS Extended (Journaled), or APFS as the filesystem type.If formatting an entire drive, ensure GUID is selected.
-- Please note that if you use APFS, you will not have a bootable Recovery partition.
-- It is recommended that you only use APFS if the target drive is an SSD.
-- If you decide to use APFS, a custom booting method will be installed by the post-install tool, as the firmware of these unsupported machines does not natively support booting from APFS volumes. It is not quite as clean as native booting, but will not cause any issues while running High Sierra. A demo of the modified booting process can be viewed here.
7. Install macOS normally onto the desired volume.
8. When the install completes, reboot back onto the installer drive.This time, open the 'macOS Post Install' application.
9. In the application, select the Mac model you are using. The optimalpatches will be selected for you based on the model you select. You canalso select other patches of your choosing.
-- The 'i' button next to each patch will show more details about the respective patch.
10. Select the volume you have just installed macOS High Sierra on, andclick 'Patch.' When it finishes patching, click 'Reboot'. It may sitthere for a few moments rebuilding caches before rebooting.
-- If for somereason the system fails to work correctly after rebooting, boot backinto your installer drive, run the post install patch again, and select'Force Cache Rebuild' before rebooting. This isn't necessary under mostcircumstances.
11. When it reboots, it should now boot into a fully working copy ofmacOS High Sierra.
Additional Info:
- If selected in the macOS Post Install tool, your High Sierra install will have a program named 'Patch Updater' located in your /Applications/Utilities folder. This program will alert you when new updates to patches are available for your machine, and will prompt you to install them. If you do not have Patch Updater installed, but would like it, you can download and run the script found here to do so.
Updates
System updates, such as 10.13.1, should install normally if 'Software Update Patch' was selected in the macOS Post Install tool, or installed using the Patch Updater program. If for some reason updates aren't showing up, or you did not apply the patch, you can install it manually using the script found here.
-- If the machine does not start up properly after applying a system update, you will need to boot off your patched installer volume, and re-run the post-install patch on your High Sierra volume. Ensure you select 'Force Cache Rebuild' before rebooting.
