Dropped keystrokes and severe execution latency in macro action sequences

Bugs or Unexpected Behavior
1

Describe the bug

Regression Notice: These exact triggers and action sequences operated without issue for over 18 months. The dropped inputs and execution delays began only after updating to recent BTT builds.

There is severe input dropping and execution latency in BetterTouchTool sequential macro workflows. Keyboard actions inside action chains are frequently missed or dropped entirely unless artificial delays (e.g., 0.60s) or duplicated identical action steps are added between items.

Specifically observed behaviors:

  1. Dropped Keystrokes in Macro Chains: Keystrokes fail to execute following clipboard/paste operations unless significant delays are inserted. For example, a Right Arrow action placed after Shift+Cmd+V fails to execute unless preceded by an (Async) Delay next action by 0.60 Seconds.

  2. Failed/Skipped Shortcut Execution: Keyboard shortcuts fail to fire on the initial trigger. Executing Shift+Cmd+Down once fails to perform the selection; duplicating the exact Shift+Cmd+Down action twice with 0.38s async delays between them is required for reliable execution.

Device information

  • Type of Mac: MacBook Pro 14-inch (2021), Apple M1 Pro, 32 GB RAM

  • macOS version: macOS Tahoe 26.7

Additional information

  • Workflows were stable for 18+ months prior to recent updates.

  • System has been restarted to confirm it is not a temporary macOS background process issue.

  • Issue is persistent on build 2026092901.

  • No crash logs generated (the issue pertains to keystroke execution delays and dropped inputs rather than an application crash).
