Las night while I was rotting my mind browsing YouTube, I stumbled upon
a tutorial for installing OpenCore Legacy Patcher, a collection of
utilities to facilitate installation of macOS Monterey, Ventura, Sonoma
on Intel Macs too old or otherwise ineligible, as determined by Apple. I
had never heard of this hack before, and I'm wondering if anyone in this
group has had experience with it. Or is it too good to be true?
I have am early 2025 MacBook Air that is not supposed to go beyond
Monterey, so it's entering its final year of macOS updates. It's not
that the newer macOS versions have major features that would compel an unauthorized upgrade. At this point I'm just asking out of curiosity.
HISTORY: One-upon-a-time I had a G4 iMac that wasn't supposed to go
beyond Tiger, and using a hack managed to get it up and running in
Leopard. It ran flawlessly, with no known incompatibilities, but was
noticeably slower, which took some getting used to.
MORE HISTORY: I still have an old plastic MacBook that I keep around for
a few legacy apps. It topped out at El Capitan, which made it unusably
slow. I put an SSD in it for a time, which got the speed back, but I
eventually sprung for a newer Mac, and reverted the old MacBook back to spinning rust. At a later time I downgraded from El Capitan back to
Yosemite, and performance improved.
