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.

-- 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.

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.
