# Running Flutter Desktop on MacOS

Flutter Desktop used to be a separate experimental project, and it was moved to the flutter GitHub repository recently as it has gotten more mature.

The doc says that it is easiest to run a Flutter desktop app on MacOS, but that it still requires some tinkering if you want to compile and run natively on Windows and Linux.

The official doc (see screenshot below. link here) actually describes the whole process, and yet, since I wasn't reading very carefully, I missed some important information. So take a look at this, then scroll down to see the commands I actually had to run.

The point I had missed was "you must be on the master branch". I was on the beta branch, and so I assumed that I would automatically get the feature. I was wrong!

 % flutter config --enable-macos-desktop
Setting "enable-macos-desktop" value to "true".

You may need to restart any open editors for them to read new settings.

% flutter config
...

Settings:
enable-web: true
enable-macos-desktop: true (Unavailable)


It's only after I switched to the master branch that macos-desktop was made available.

% flutter channel master

Switching to flutter channel 'master'...
git: Switched to a new branch 'master'
git: Branch 'master' set up to track remote branch 'master' from 'origin'.

% flutter config

Settings:

enable-macos-desktop: true


Then I created an app with flutter create app, and ran it:

% flutter run

Hurray!
