Now, just because you can run macOS Monterey on unsupported Macs in many cases does not necessarily mean you should. The older the Mac, the less stellar the performance will be, whereas later model unsupported Macs can run Monterey just fine (for example, the 2014 MacBook Pro line).
Apple updates its macOS desktop and laptop operating system once a year, like clockwork, bringing new features and improvements. That's all very well, but Apple's most recent version of macOS – Monterey – won't run on MacBook Air, MacBook Pro or iMac models that launched before late 2015.

How to install the OS from USB
Xserve (Early 2008 or newer) Over the weekend, I installed #macOS Monterey on my 15-year-old iMac, thanks to OpenCore Legacy Patcher. It works great! (The chipset misidentifies my upgraded 2.6 GHz CPU as 700 MHz. Most ≥2008 Macs don't require new hardware!)
