This isn’t mentioned on the Live 3 web pages or in the user manual and no minimum OS is listed so just posting it here.
The following macOS versions are supported:
macOS Big Sur, macOS Monterey, macOS Ventura, macOS Sequoia, macOS Sonoma, macOS Tahoe
To be found at product page.
Apparently you’re better at reading the product page than I am but my experience was that it crashed immediately after the splash screen on Monterey and the solutions support chat offered ( deleting the prefs folder ) did not resolve the crashes. This on a 2017 MacBook Pro. Just a PSA.
