Sometimes, when you open Heptabase on macOS, the icon may show up in the Dock, yet no application window appears on‑screen.
If you encounter this issue, please follow these steps to resolve it:
Make sure Heptabase is the active app
Click the Heptabase icon in the Dock so its name shows in the top‑left corner of the menu bar.
Bring all windows forward
In the macOS menu bar, click Window ▸ Bring All to Front.
Zoom the window
Still under Window, select Zoom.
The main Heptabase window should now resize and appear on your screen.
If the problem recurs, please let us know!
