macOS Sequoia: Editor/Librarian or Korg System Updater can't connect to hardware

macOS Sequoia introduces permissions settings for network access for individual applications. If set incorrectly, this can block the Editor/Librarian or System Updater from accessing the multi/poly. To check this:

1. Quit the Editor/Librarian or Korg System Updater.
2. Open System Settings.
3. Select "Privacy & Security" and then the sub-section "Local Network."
4. You will see entries to enable or disable different applications. Find the entry for multi/poly Editor Librarian or Korg System Updater.
5. If it is disabled, turn it on, and then open the Editor/Librarian or Korg System Updater; they should now be able to connect to the hardware.
