Hello @rayski
The fix is out. Roon 2.71 build 1683 was released yesterday and it specifically fixes Roon Server failing to start on macOS 12 and 13. Your crash report matches it exactly.
Please download it from
and install over the existing copy in Applications, then launch it from Applications rather than from the mounted disk image. Your library and settings are untouched.
On your question about rolling back to a previous version: we do not recommend it, and it is worth knowing why. The database format is upgraded when you move to a new release, and older builds cannot read the upgraded database. Going backwards would mean restoring a backup taken before the update, and anything added since would be lost. As a rule, the way out of a bad release is forward rather than back, which in this case is build 1683.
Please let us know once you are on 1683 and everything is back up.
