Apple's a $1T Company for a Reason 

We realize Macs aren't the only computers that can quadruple-boot. In fact, the theoretical limit is 128 OS's on one computer, and the current actual record is 79, set by Janus Donders in 2022, but if anything other than a Mac is being used, Windows and Linux are probably the only OS's that run stably. Quadruple-booting a Mac avoids bothering with "hackintoshing" and the other OSs run more stably as well, at least, with the right model and configurations.

And Breaking Them

Booting into all 4 of the major operating systems (macOS, Windows, Linux, and chromeOS) in less than 2 minutes on 1 laptop . . .

T2 Security Chips

You'll get the most bang for your buck from the newer Intel-based Macs; however, Apple integrated their secuity "T-chips" into most of their Macs beginning in 2016.   It's not impossible to quad-boot these Macs, but they do involve a higher level of complexity to the process, particularly when it comes to installing Linux.    You'll want to get familiar with the info put together by the good folks over at t2linux.org, or at least thank them, since we've duplicated much of the guidance here on this website.

Flex versus Brunch

When Google says they "officially support" a competitor's device, they mean, they expect you to wipe the drive and only have chromeOS on it, because that's exactly what their chromeOS Flex installer will do.    This is fine on Macs with a removable HD and/or SDXC slots, neither of which Macs after 2015 has.    Thanks to a coder named sebanc though, we can install regular chromeOS to a partition using an emulator he programmed called Brunch.    Ideally, we could install either to an ultra slim USB-C flashdrive.

The Bootloaders

rEFInd at the Core

None of this would be possible without a powerfully flexible boot manager like rEFInd, which Rod Smith has ben developing and maintaining for over 15 years now.    It sits on the invisible EFI partition and looks for bootloaders in the same location.    Great thing about it is, if the bootloader for one of the OS's fails, perhaps due to an update, you can simply boot into a different OS from rEFInd and probably fix the issue.    Not only is it functionally amazing, but it's form can also be customized to amaze.    We themed it with a minimalist look for the "Think quadratic" brand.


Years of Research and Compiling

So You Don't Have To

To be clear, we're not coders by any means, but we know how to research, follow a guide, find and mimic patterns, compile information, and present it in a useable and compelling form.    Below are the different information channels to help you "Think quadratic." 

FAQ

Don't be "that person" who sends a question before reading all the material we've put together. At least take a look at the frequently asked questions as you'll likely get an answer much faster that way.
