Has anyone tried downgrading M2 ultra mac studio from Ventura to Monterey?

[hsiunghsiung]

Was wondering if anyone has downgraded their M2 mac studio from Ventura to Monterey? Usually the rule of thumb is that you can't downgrade lower than the OS that it shipped with, but I am curious if workarounds have been discovered.

I've been using a lightroom 5 perpetual app on a macbook air m1 with Monterey, and it works seamlessly. Now that I've purchased a mac studio m2 that comes with ventura preloaded, it's having issues with lightroom 5.

Saw this thread and link that someone suggested works:

the rule is that cannot downgrade to an OS older the models launch OS.

ie Mac Mini 2018 if bought in 2020 would have shipped with 11.x but could downgrade to 10.14 as that was what 2018 originally launched with.
USB installer downloaded and wipe the current Storage.

with Ventura firmly established and sonoma on the way then don’t see them adding M2 support to Monterey installer.

believe no M2 system shipped with Monterey.

M1 Studios launched with Monterey so they would be able to do the USB installer, but a Ventura shipped M1 Studio recovery partition would remain Ventura,
however M2 Studio launced with Ventura as launch OS.

that thread is for M1 Studio shipping with Ventura, not an M2.

The M2 MacBook Air did ship with Monterey, but that chip is pretty different from M2 Max/Ultra. I don't know that Monterey would support the newer M2 chips, at least not in a stable form. There may have been some rudimentary support for testing those chips.

Personally, I think I'd be looking into updating to a supported Lightroom version over risking problems with an experimental install of an earlier MacOS.

M1 Studio can run Monterey.

M2 Studio REQUIRES Ventura. It WILL NOT BOOT into Monterey.

You might be able to run Monterey (or an older version) in a VM… but not natively.
