Unable to change catalog location for Astrometry catalogs stored on remote drive.

Software Siril
1

Siril 1.4.4, macOS 26.6.2 (25G82) Taho Mac Studio Apple M2 Ultra.
Steps:

  1. place the KStars catalogs in a folder on a remote drive; ensure permissions allow access.
  2. start up Siril 1.4.4
  3. Click “hamburger” icon and select “Preferences” from dropdown.
  4. Select Astrometry on left menu column.
  5. Find: “Local Star Catalogues (more info)” in Astrometry selections.
  6. Find: “namedstars.dat: (None)” with the folder icon and click in the selection box containing the icon and text.
  7. Follow file selector to the remote drive and then the path to the folder containing the folder with the named stars.dat file.
    Here is the problem: You cannot select the “Open” button on either the folder containing the catalog .dat files nor using the folder . The open button is “ghosted” and cannot be selected.
    Suspected cause The permissible file types may not be specified for selection.
    You probably want: (assuming swift)
    .allowsMultipleSelection = false
    .canChooseDirectories = false
    .allowedFileTypes = [“dat”, “xz”]
