How to customize the “About This Mac” section of a Mac
The “About This Mac” window contains information relating to your computer specifications and OS version, and is useful for quickly checking any of those details. However, it's a little impersonal, and often (on a Hackintosh), incorrect. If, like me, you enjoy customising your machine to your own personal taste then this guide should help somewhat, by jazzing up the “About This Mac” section.If you own a Hackintosh then this guide may be of especial utility, as their non-Apple components and varied range of specifications can mean that “About This Mac” contains errors, or fails to provide any information at all. For these users the guide may be of functional use. If you're on a real Mac, it'll be for more aesthetic purposes.
These edits will work on macOS versions from Yosemite (10.10) to Sierra (10.12). Prior to that the file locations were different, but can still be modified with a little research. Let me know if you need any other file locations, and on which OS, and I'll try to oblige.
Changes do not always survive a system update, though often do.
For all of these examples, BACK UP the original file to a safe location on your computer before modifying it, in case of a mistake or wanting to revert to stock later.
