Hi Natron users,
There seems to be a nasty bug affecting Natron on macOS Monterey, see github issue #712.
Basically, Natron cannot load Natron projects reliably on macOS Monterey.
It is very difficult to debug this, as it is seemingly due to a change in the OS. All Natron versions, at least from 2.1.9, are affected, so this is not due to a source code change or dependency upgrade.
If you have a system with macOS Monterey ould you please try to reproduce this bug, and report in github issue #712 if you can or cannot reproduce it.
Also, if you are using Natron, I wouldn’t recommend upgrading to Monterey for now.
