Maximize a Mac window without entering full screen
By the Windsify team Wondering Works ·
To make a window fill the desktop while staying alongside other windows, use Fill or resize it instead of entering macOS full-screen mode. For side-by-side layouts, see the window tiling guide.
1. Try native Fill first
On macOS 15 or later, select a regular window and look under Window → Move & Resize for Fill. Supported keyboards can use Fn+Control+F to fill and Fn+Control+R to restore. Menu wording can vary by macOS version. Control+Command+F is a different action: full-screen mode. See Apple’s tiling shortcuts. Use the menu if a PC keyboard does not send Fn to macOS.
2. Fill, zoom and full screen are different
| Goal | Action |
|---|---|
| Occupy the current desktop | Fill or resize |
| Use a separate full-screen space | Full-screen mode |
| Keep two windows side by side | Tile windows or use Split View as appropriate |
| Put a window in the Dock | Minimize |
Zoom can size a window to its contents rather than the whole desktop. Fixed-size dialogs and application size limits can prevent a window from filling the screen.
3. Fill and restore with Windsify Pro
- Enable window management, grant Accessibility access and confirm an active Pro trial or license.
- In General → Maximized window area, choose Keep Dock visible. This reserves space; it does not change the system’s Dock auto-hide preference.
- Select a regular floating window and press Win+Up. On an Apple keyboard, Command is the corresponding Win key.
- Press Win+Down to restore the saved placement. Without a saved placement to restore, this shortcut minimizes the window.
Win+Up is layout-aware: a side-half window moves into an upper quarter instead of filling the desktop. Start with a floating window when testing this example.
If the Dock is hidden or the window stays smaller
Check the macOS Dock auto-hide setting, full-screen state, application size limits, display arrangement and Windsify’s window engine. Reserving Dock space does not override a system preference to hide it. Window management is a Pro feature; after the trial, it requires an active license.
