Native Instant Space Switching on macOS

Original Article ↗ Hacker News Discussion ↗

Many macOS users are frustrated that switching between virtual desktops (“Spaces”) triggers a slow, unskippable animation that delays input focus and feels increasingly jarring on high‑refresh‑rate displays. A new tool, InstantSpaceSwitcher, along with options in BetterTouchTool and tiling window managers like Aerospace and yabai, attempts to bypass or speed up this animation to make workspace switching feel instant and more like i3‑style environments on Linux. The exchange highlights broader dissatisfaction with macOS window management, Apple’s reluctance to expose low-level customization, and a growing trend of power users turning to third‑party tools or Linux for more responsive, configurable workflows.

Reaction to the instant space-switching approach

  • Many welcome the “fake high‑velocity swipe” trick as a clever, lightweight way to eliminate the slow Spaces animation without disabling SIP or replacing the whole window manager.
  • Several report it “just works” and is a major quality‑of‑life improvement, especially on newer 120 Hz Macs where the animation feels even slower.
  • Some worry about possible edge‑case bugs from simulating gestures at high velocity, but no concrete failures are reported in the thread.

Frustration with macOS Spaces & animations

  • The core complaint: space switching feels sluggish, focus stays on the old space until animation ends, and this causes keystrokes to go to the wrong window.
  • The issue is worse on ProMotion/120 Hz screens; switching is measurably slower than on 60 Hz.
  • “Reduce Motion” replaces slide with a fade but doesn’t make it faster and also propagates a “prefers reduced motion” flag into browsers, breaking some sites unless overridden.
  • Some people genuinely like the animation and find it gives spatial context, especially with trackpad swipes.

Window & workspace management workflows

  • Heavy users of multiple desktops use Spaces like virtual desktops: one per project/app cluster, with hotkeys mapped to specific spaces for O(1) access.
  • Others abandon Spaces entirely and rely on:
    • app/window hotkeys,
    • cmd+tab / cmd+` variations,
    • or third‑party switchers for per‑window alt‑tab semantics.
  • People miss older macOS features: grid layouts of spaces, persistent space names, and more discoverable controls.

Third‑party tools & alternatives

  • Frequent mentions:
    • Tiling/space tools: Aerospace, yabai, OmniWM, FlashSpace.
    • Window tilers: Rectangle, Moom, Raycast, BetterSnapTool.
    • Switchers: AltTab, Contexts, Raycast hotkeys.
    • Misc: BetterTouchTool (includes “move space without animation” and trackpad gestures), WinPin, WhichSpace.
  • Some rely on SIP‑requiring tools (yabai, older hacks), others reject anything that needs SIP disabled, especially on work machines.

Accessibility and UX quality concerns

  • At least one person with a vestibular disorder finds the space animation disorienting and views Apple’s inaction as an accessibility failure.
  • Several argue that even small UI delays (space switching, terminal startup, fullscreen transitions) harm “flow” and make the OS feel heavy.
  • There is broader criticism that Apple ignores “annoying but not blocking” bugs, regresses window management over time, and offers few tunable settings for power users, pushing many toward Linux/i3‑style environments.
