Slidr FAQ
Trackpad gestures, external monitors, requirements and pricing.
How do I change volume on a Mac with the trackpad?
Install Slidr, open it from Applications and allow Accessibility access in System Settings. Slide up or down along the right edge of your MacBook trackpad to increase or decrease volume.
Can I control brightness on an external monitor from my MacBook trackpad?
Slidr supports external monitor brightness via DDC. The brightness gesture uses the left trackpad edge by default.
Is Slidr free, and how much does it cost?
Slidr has a 3-day free trial with no payment required. Continuing after the trial costs $4.99 USD as a single payment.
Which versions of macOS does Slidr support?
Slidr requires macOS 12 Monterey or later.
Does Slidr need Accessibility permission, and why?
Yes. Slidr requests Accessibility permission on first launch so it can read trackpad gestures. Allow it in System Settings > Privacy & Security > Accessibility.
How is Slidr different from BetterTouchTool and MonitorControl?
Slidr provides volume and brightness control from trackpad edges out of the box, with haptic feedback and external monitor brightness via DDC. BetterTouchTool is a paid Mac input customisation tool for gestures, shortcuts and actions, including continuous gestures; you build your own setup. MonitorControl is free and open source, controlling external display brightness and volume via DDC from keyboard brightness/volume keys and a menu bar slider. It is not a trackpad gesture tool. See the Slidr vs BetterTouchTool vs MonitorControl comparison for pricing, setup and official product sources.
Can I use Slidr with a Magic Trackpad?
Yes. Slidr supports a MacBook's built-in trackpad or a Magic Trackpad, with macOS 12 Monterey or later.
Can I avoid accidental gestures while typing?
Slidr automatically ignores gestures while you type. You can also limit gestures to the bottom quarter of the trackpad or require a modifier key before gestures activate.
