Possible performance issues on macOS and Linux resulting from a previous version of Daedalus which is still running.
On macOS and Linux, the Daedalus installer is not properly checking if the previous version of Daedalus is still running, allowing users to unintentionally install over a running copy of Daedalus.
If this happens, users are recommended to do the following. Delete the Daedalus application and keep the state directory, then attempt installation again. Users should manually check that Daedalus is not running when performing installation on macOS and Linux operating systems until this issue is fixed.
