Personally, I did it on my Mac Pro ’08 (MacPro3,1), which officially supports only OS X 10.11 „El Capitan“. With the „macOS High Sierra Patcher“ I managed to install the latest macOS (10.13). I don't see any system folder in the usb installer, only 3 items, efi folder, efi-backups folder and the install OS X el capitan file. No system folder? How do I apply this patch?, the other times there was a command you used but it was a tar file, this is two sepatate files.

Yosemite and El Capitan System Font Patcher. Change the system font of Mac OS X Yosemite and El Capitan. Inspired by FiraSystemFontReplacement. Maybe it's just me, but for such a new and modern interface, Helvetica Neue feels ancient, and Helvetica is already everywhere A more futuristic font such as Avenir Next may be a better choice. El Capitan Patcher Download 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.
With yesterday’s software updates El Capitan fell off the security patch bandwagon, as expected. Apply historically only patches software for the current software plus two versions prior. So that means Mojave, High Sierra, and Sierra. The good news though, is that if you have a compatible computer software upgrades from Apple are free.
Not sure what version you are running? Here’s how to find out. Don’t assume that you’re on the latest version because your computer automatically updates itself. Normally auto-update only installs updates for your current software. Usually it will offer to upgrade you to a new version once, but if you dismiss the offer to upgrade it doesn’t persist. You then have to choose to get it from the Mac App Store.
If you have a computer running El Capitan still I highly recommend you upgrade to a newer version if possible, or retire your computer if it cannot be upgraded. As security holes are found, Apple will no longer patch El Capitan. And at some point shortly after that software developers will stop making their software compatible which you’ll first notice means your web browser will stop functioning properly on the internet.
If you insist on keeping an obsolete computer please be careful and be aware of the risks. You should at the very least stop using Safari since that’s communicating directly with the internet and is no longer going to get updated. Firefox is a good alternative because they often support system software for two years longer than Apple does. Google Chrome only maintains support about one year after.
As an alternative to completely retiring the computer, you can install an alternate OS such as Linux, but the specifics of that are far more than I could cover in this post.
For most people, I would suggest upgrading to macOS Mojave if your Mac supports it. Mojave will receive security patches until the fall of 2021. High Sierra will get security patches until fall of 2020, and Sierra until the

Download High Sierra on the Mac App Store.
macOS Sierra has the same requirements as High Sierra, so if you can I’d suggest going to High Sierra because it will receive security patches for longer. But if for some reason you’d rather move to Sierra you can download Sierra on the Mac App Store.
