MuseScore Studio 4.6.2 is now available!
This update fixes several important regressions.
It also restores compatibility with macOS 10.15 and 11, which was lost in 4.6 when we updated to Qt 6.9.2. We've now patched Qt to maintain compatibility with those versions as well as the very latest macOS Tahoe 26.
