Elite from Ian Bells website for Windows Horizon does not work with MacOS Horizon. Why?
The Windows and MacOS versions of Horizon use slightly different file naming conventions. To get Elite for Windows Horizon working with MacOS Horizon, do the following. Rename TCODE as T.CODE and DCODE as D.CODE. Now rename all DM* files as D.M* e.g. DMOA becomes D.MOA . Elite should now work with MacOS Horizon.
