Get back to MuseScore 3 (Mac)

Hello,

I downloaded MuseScore 4 today, as it was available, and really, it's bad for me. There are so many things missing, I can't even work on my musics like before, because a lot of sounds are missing, many settings on my scores are gone, it's not ergonomic at all...

The thing is, it seems I can't download MuseScore 3 on internet...
So, it would be very nice if somebody could send me MuseScore 3 for Mac (on the last version before MS4), at least to wait for when MS4 will be good enough, please.

Thank you in advance
