Why isn't MuseScore available for my operating system?
MuseScore strives to support as many operating systems and their versions as possible.
Unfortunately, due to the nature of some, it becomes difficult, or impossible for the third party tools and components MuseScore is dependant upon to support, which in turn means we are unable.
For platforms in which it is possible, it could mean that we are awaiting a maintainer for it. If you are interested in becoming one, please contact us.
