CursorCrossing Makes Every Display Edge a Door

Field notes

The utility is designed around the boundary behavior of macOS multi-display layouts: it leaves ordinary pointer movement alone, then adds crossings where the system would stop the cursor. Users can also draw “portals” between screens that meet only at a corner, with positions mapped proportionally across the two displays. The page lists macOS 13 or later, a seven-day trial, and either £1.99 monthly or £9.99 lifetime pricing.
