Hi.
I’m on MacOS Sonoma 14.6 and when upgrading MusicBrainz Picard, I get this information:
=> Upgrading musicbrainz-picard
=> Caveats
musicbrainz-picard is built for Intel macOS and so requires Rosetta 2 to be installed.
You can install Rosetta 2 with:
softwareupdate --install-rosetta --agree-to-license
Note that it is very difficult to remove Rosetta 2 once it is installed.
MB is still working without issues, thus my question to the community: how relevant is the information regarding Rosetta 2 and what should I do?
TIA.

If you are running current Picard on a newer Mac with ARM processor (Apple Silicon) you need Rosetta 2. Rosetta 2 provides a compatibility layer to run code compiled for Intel CPUs to run on the ARM CPU.
If the Picard app is running on your system you either have a Intel CPU or an ARM CPU and Rosetta 2 is already installed. Otherwise it wouldn’t run.

Just for completeness: the goal is of course to provide a version of Picard that is natively running on Apple Silicon.
There are a few challenges to overcome, but things are mostly in place already. See also the recent discussion at Contributing to Picard 3.0
