- 2006-2008 MacBooks (MacBook 1,1, 2,1 3,1 and 4,1)
- 2008 MacBook Air (MacBookAir 1,1)
-- Note: Make sure SIP is disabled on the system you intend to installHigh Sierra on. If it's not or you're unsure, just boot into your Recoverypartition of your currently installed copy of OS X, open Terminal, andrun 'csrutil disable'.
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
- 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.
- 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.
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.
