Questions, answered.

• What is FAST?

  FAST (Fix Apple's Shitty Tiling) is a native macOS window manager for macOS 14 Sonoma and newer. It tiles your windows into visual zones on every connected display, saves entire workspaces as Scenes you can restore in one click, and gives every action a keyboard shortcut, a Shortcuts action, a URL and a CLI command. One-time purchase from €29, no subscription, no telemetry.

• Doesn't macOS already have built-in window tiling?

  It does, and for splitting two windows on one screen it is fine. macOS tiles the window you are dragging right now; it has no concept of a workspace you can name, save and bring back. FAST adds persistent Scenes across changing displays, per-display layouts, stacks that hold a window behind another instead of replacing it, Undo for every geometry change, and a CLI and URL scheme for automation.

• Why do my windows move when I unplug an external monitor?

  macOS remembers window positions as pixel coordinates on a display that no longer exists, so when the display goes away it collapses everything onto the remaining screen — and plugging back in does not undo it. A FAST Scene stores display roles, layouts and matched app windows instead of coordinates, so restoring it puts your workspace back on whatever displays are connected at that moment.

• Where is my data stored?

  Your workspace data stays on your Mac: no cloud sync and no telemetry. Scenes and rules live in portable local JSON you can export and import from Settings. Internet access is only needed to activate and periodically validate your Polar license; a 7-day offline grace period keeps FAST usable between checks.

• Does FAST need to disable System Integrity Protection?

  No. FAST uses only the public macOS Accessibility API. You grant Accessibility permission once, and SIP stays fully enabled. There is no kernel extension, no modified system volume and no reduced-security boot.

• Which macOS versions are supported?

  FAST supports macOS 14 Sonoma and newer.

• Is there a free trial?

  There is no time-limited trial. Instead every purchase carries a 14-day money-back guarantee: buy FAST, use all of it, and if it is not for you write one email and get a full refund without forms or questions.

• Is it a subscription?

  No. FAST is a one-time purchase with lifetime updates. Buy it once, use it forever.

• How does the license work across devices?

  Choose a 1, 2, or 3-Mac license at checkout. Polar issues the license key and tracks only its allowed activations. FAST validates the key at launch, stores it in the macOS Keychain, sends no workspace content, and keeps working offline for up to 7 days after a successful check.

• Can I move my license to a new Mac?

  Yes. Settings › License › Deactivate This Mac releases the Polar activation so that device seat can be used on another Mac. The license key and activation ID live in the macOS Keychain, and activation sends no hardware identifier, window title, Scene, rule or usage data.

• Does FAST work with Spaces and Mission Control?

  FAST manages windows on the display you are looking at and does not create or manage its own Spaces. Tools that do that — yabai-style private Space creation — need System Integrity Protection partially disabled, and FAST deliberately stays on the public Accessibility API instead. It differentiates through portable semantic Scenes and direct visual manipulation rather than private WindowServer access.

• Can I buy FAST for a whole team?

  The standard licenses cover 1, 2 or 3 Macs. For anything larger, write to contact@03-studios.com and we will sort it out directly.

• Will FAST rearrange my windows without asking?

  Never by default. New installations never rearrange or hide windows automatically. Continuous window rules and arrange-on-launch are opt-in, visible, and editable in Settings.

• What exactly is a Scene?

  A Scene captures the meaning of your workspace, not fragile pixel coordinates: display roles, layout choices and divider weights, theme, accent, tile inset, matched application windows, complete multi-zone claims and active stack members. Restoring a Scene re-matches open windows, launches missing apps, maps the Scene onto the available displays, and keeps an Undo snapshot.

• Does it work with multiple displays and ultrawides?

  Yes. Every connected monitor gets its own layout, backdrop, and saved app assignments. A native 5120×1440 display automatically gets the dedicated five-tile 49″ Super Ultrawide layout.

• Can I change the keyboard shortcuts?

  Every shortcut can be changed or removed in Settings, including the Vim-style ⌃⌥ H/J/K/L navigation, ⌃⌥←/→ layout switching, ⌃⌥↩ Focus Mode, ⌃⌥A arrange and ⌃⌥Z undo. FAST keeps a 30-step undo history of geometry, assignment and stack changes.

  Complete keyboard reference→
• Can I script FAST?

  Yes. Clicks, keyboard shortcuts, the Shortcuts app, Siri, a fast:// URL scheme and the bundled fastctl command-line tool all execute the same typed actions, so placement behaves identically everywhere and Undo works no matter where a command came from. The Shortcuts and Siri actions are Arrange into Zones, Focus Mode, Undo and Open Scene.

• What if it's not for me?

  Every purchase comes with a 14-day money-back guarantee. Write one email and you get a full refund, no questions, no forms.

• What's on the roadmap?

  More visual themes beyond the five built-in accent systems, deeper Scene automation, and more ways to trigger actions. The built-in update checker links each stable release the moment it ships.
