Australian developer releases GridLion to restore macOS grid-based desktop navigation

An Australian developer has released GridLion, a new application designed to restore the grid-based layout for macOS virtual desktops that was removed in the macOS Lion update. The software enables users to navigate virtual desktops, known as Spaces, in a configurable grid rather than the current horizontal line interface provided by the native Mission Control system.

The developer, a former iOS engineer who migrated to macOS in 2006 with version 10.5 Leopard, cited frustration with the loss of spatial memory capabilities in the native system as the primary motivation for the project. While macOS Leopard allowed virtual desktops to be arranged in a customisable grid, the subsequent release of macOS Lion in 2011 restricted them to a single horizontal row, a change the developer described as a step backwards for workflow efficiency.

GridLion was built with assistance from large language models, with the developer creating a functional prototype within a day before spending a month refining it into a polished tool. The application relies on private APIs to function, which prevents its distribution on the Mac App Store. Instead, the software is sold via Lemon Squeezy, a Merchant of Record that handles purchases, refunds, and tax compliance, including GST for Australian customers.

The app requires users to grant significant system permissions, including macOS Accessibility and Screen and System Audio Recording capabilities. The developer noted that the approval flow for these permissions on macOS is complex, involving multiple prompts and system settings adjustments, which can be a barrier for users. The software also includes a license key system managed through Lemon Squeezy to validate purchases.

Despite its capabilities, the developer acknowledged limitations in the current version, such as the lack of reliable APIs for moving spaces between displays or assigning applications to specific grid locations upon load. The tool serves as a workaround for users who prefer dedicated workspaces over window management solutions like Yabai or Aerospace, which the developer rejected due to their focus on window tiling rather than distinct desktop environments.

The release highlights the evolving landscape of software distribution outside traditional app stores, with the developer noting the vetting process required by Lemon Squeezy to demonstrate reputation. While the developer expressed interest in selling software directly, the hurdles compared to the hands-off nature of App Store distribution remain significant. The app remains available for download via the developer’s website and Lemon Squeezy.
